Hmmmm... I'm sure it'll need a linked scientific study to actually back up the claim. (And every speed-reading product I've seen has usually had a decrease in comprehension rate...)

It's a clever idea, but anecdotally, from my experience, I'm finding it slows down my reading -- I'm having a hard time processing the blurbs because I don't read "linearly" -- I scan content to find the relevant parts, and the color changes are making it difficult to scan (because my eye can no longer use color to determine what is scannable and what isn't), and multiple columns is actually making it even more difficult (it looks like the blue in column 1 leads into the blue in column 2, instead of the blue at the next line of column 1). By trying to force me to read line-by-line, instead of scanning efficiently, it's making me read slower.

But that's just for short-form stuff. It could turn out to be faster for some layouts, and slower for others. But honestly, I've never felt I had difficulty locating the start of the next line... is this a problem that needs solving? But nevertheless, it's certainly a good example of clever out-of-the-box thinking.

I normally read around 600 to 1000 wpm (depending on how dense or vapid it is). This speeds up my reading wayyyyy past that. 1500 wpm? And I was barely trying. It does look super fucking ugly, but it totally works for me. They need to bring in an army of designers and make software geared towards legal assistants / lawyers because they need this desperately.

I read at 146 words per minute, and that is average text. I probably read slower when the material is hard. Over the past year or so I went through roughly 90% of Plato's work (like, really), The Quran (partially), On the Nature of Things, Meditations of Marcus Aurelius, Discourses by Epictetus, How to Read by M. Adler, Alchemy of Happiness by Ghazalli, etc.... I also read several short text including James Allen, Xenophon, etc... Currently I am reading Jacques Rousseau, and getting back soon to Adam Smith Wealth of Nations... I also started but did not finish yet the Communist Manifesto, How we think (slightly), Prior Analytics (slightly) and perhaps my hardest read ever, Suma Theologica. I am 100% sure I forgot a couple of books I read. Many of these writings I re-read a few times because they are hard to grasp for me. AT 146 words/minute. I am an inefficient reader, and I never knew it. I am going to thoroughly research ways to improve this.

None of those are works that should be speed-read. Thomas Aquinas, Plato, Epictetus, the Qur'an, and (above all) the Bible should be rolled around the mouth, tasted deeply, and either made a part of you or thoroughly spit out if they are found indigestible. If your mechanical reading speed is the limiting factor in reading these works, you're doing it wrong.

Plato is mostly dialogues and it is only hard in the sense that I have to extract the philosophy out of the text, plus Socrates goes around and around. Epictetus is ok as well, the text is simple to read, and I found myself taking many notes and comparing his text to others. Modern interpretation of the Quran with commentary is helpful, the thing about it being that each chapter is somewhat separated from the rest. Bible, I picked than put it back down with humility because I just knew I could not grasp it. Aquinas is hard to follow, imo he is a logician before a theologian and I know nothing of the first and very little of the second science. However I am very interested in the subject of his writing. I agree it is "accidentally" mechanical reading although my goal is "understanding." I just started to read heavily the past 2 years and this is my beginner's eagerness.

I don't know if you're reading the Bible out of cultural or religious motives; if it's the latter, I find that praying for understanding helps me understand. You could try it, if you choose.

Religious curiosity, although I am not Christian. I certainly will pray for understanding. Thanks J..

I agree, but god damn, I am jealous. I have two small children and I've finished one book this year. (Coders at Work by Peter Siebel, I highly recommend it.)

My wife reads 10x faster than I do but completely eschews the kind of reading I like (viz, literature). But of course, now that, y'know, she has kids too, her overall reading speed is strangely reduced as well.

Anyway, at a first glance I found the line coloring helpful.

I have three small children, and I heartily sympathize. Any reading I do comes out of much-needed sleeping time.

Why the Bible above all?

Because the King James bible had considerable effort to translate original texts into best possible English, preserving meaning but also creating a suitably "glorious" text.

Very many concepts, words, metaphors, etc come from the King James translation.

Ignoring any religious stuff - it's a good read.

EDIT: corrected my st / king error!

The King James Bible is not a that close translation of the original texts. It contains many translation errors and additions by later scribes not present in older texts. Generally more recent translations of the Bible are way more accurate, due to better access and more study of sources today and due to better understanding of ancient Greek and Hebrew.

A point of view on King Jame Bible: https://bible.org/article/why-i-do-not-think-king-james-bibl...

Try the Knox bible, ( http://en.wikipedia.org/wiki/Knox's_Translation_of_the_Vulga... ):

"It was my resolve to live watchfully, and never use my tongue amiss; still, while I was in the presence of sinners, I kept my mouth gagged, dumb and patient, impotent for good. But indignation came back, and my heart burned within me, the fire kindled by my thoughts, so that at last I kept silence no longer.

"Lord, warn me of my end, and how few my days are; teach me to know my own insufficiency. See how thou hast measured my years with a brief span, how my life is nothing in thy reckoning! Nay, what is any man living but a breath that passes? Truly man walks the world like a shadow; with what vain anxiety he hoards up riches, when he cannot tell who will have the counting of them! What hopes then is mine, Lord? In thee alone I trust. Clear me of that manifold guilt which makes me the laughing-stock of fools, tongue-tied and uncomplaining, because I know that my troubles come from thee; spare me this punishment; I faint under thy powerful hand. When thou dost chasten man to punish his sins, gone is all he loved, as if the moth had fretted it away; a breath that passes, and no more. Listen, Lord to my prayer, let my cry reach thy hearing, and my tears win answer. What am I in thy sight but a passer-by, a wanderer, as all my fathers were? Thy frown relax, give me some breath of comfort, before I go away and am known no more."

-Psalm 38 (39) from Knox's Translation of the Vulgate.

Knox's translation is lucid when compared with the "correct" and dead modern translations of the bible. Try it if King James does not speak to you.

That verse is perhaps the clearest explanation I have ever read of why religion exists. Thank you.

Personally I agree, I love KJV (mainly through choral music written with biblical texts), just wondered whether he was making a subjective point like you are, or whether it was a religious point.

I'm very late to respond, but I wrote what I did as a religious point. After a lot of years of doubt on the matter, I've come to the conclusion that what the Bible contains is critically important truth. I honestly think it fails as literature, because it is incoherent unless comprehended by faith; but it is a source of comfort, encouragement, and guidance to those whom God has freely given faith beforehand.

But if you choose to read it as literature, I certainly won't stop you!

The KJV is a rubble translation influenced strongly by the desires of the king. He had translator beheaded for not translating it the way he wanted.

Besides we have MUCH better access to older sources now, and what do we find? Contradictions, contradictions everywhere.

He was not reading it for the historical / religious insight - he just liked to read English prose written as best it can be.

That was a personal remark. He's most probably a Christian. For others is Qur'an above all. And so on. For me is Bible+Church Fathers above all. :)

I like spreeder:


Set the chunk size to three for best effect. Just gradually increase it each time, and also try using it occasionally with the speed far too fast. You'll get used to subvocalizing less, and reading multiple words at once.

Of course, for complex texts like the ones you read, it's natural to read much slower. I read 600 WPM for most internet articles, but I'm sure I wouldn't read plato that fast, nor as continuously.

Since I don't find RSVP mentioned in the comments here:

That technique is called Rapid Serial Visual Presentation: http://en.wikipedia.org/wiki/Rapid_Serial_Visual_Presentatio...

(The Wikipedia article should mention saccades (http://en.wikipedia.org/wiki/Saccade) but strangely it doesn't.)

I wrote an RSVP reader in the mid-to-late 90s in QuickBasic. I'll have to see if I can dig up that code. :)

That's odd. I wrote an RSVP reader in the exact same timeframe in RealBASIC, for a Cornell Psych class (I got an A).

I am still annoyed that things like the Kindle don't have that mode.

maybe it's just me but I feel like I have a stutter thought when I read using that. It's just doesnt feel right; I think books/articles reading will be less enjoyable if I'd have to use it.

The duration needs to be based on syllables, otherwise the rhythm is totally off.

Has anyone made a syllabic RSVP reader before? Might be interesting to see how much more natural it would be (my hunch is "a lot").

I agree. I use it as a training tool, not for pleasure. I found it increased my paper reading speed, without reducing enjoyment or comprehension.

If you're not reading these works purely for edification then I assume you are working through a Great Books curriculum (http://en.wikipedia.org/wiki/Great_books ). Congratulations. The trouble will soon be finding anyone to with which discuss what you've read, especially if you work in technology where ideas are assumed to have a shelf life. Being well read can be alienating.

In terms of increasing reading speed, you may want to try the utility "dictator" for those texts which are electronic. For physical books I would run a finger under text to maintain momentum as Adler suggested in "How To Read a Book". Make notes in the text, being sure to use a custom set of symbols to speed notation. Write concise thoughts in the margin, don't go overboard.

Good luck.

I am definitely going through the G.B., with other writings from Middle Eastern background. It started when I was researching Islamic & Western texts on a particular subject and similarities. Somewhere along I happened upon Adler's book on How to Read. I agree on having no one to discuss it with, but it's ok, "I am having a discussion with the authors on the margins." If you are going through the list I'll be more than happy to have a long term dialogue (email in profile).

We are going to be integrating with Casetext (YC S13), which is an upstart competitor to Lexis/Westlaw. They're looking to revolutionize legal case research, and we're glad to be a part of it!

What techniques do you use? I read at around 600wpm, and increasing it by 50-100% seems pretty daunting.

I trained a bit speed reading when I was in higschool from some book that was translated from Russian (sorry, no idea what was the book) the main idea there was to: 1) not saying words with inner voice 2) not reading letter by letter (seeing whole word at once) 3) reading by connected words not only word by word 4) there was eye training exercise, the idea was that you had to train vision a bit to be able to read more text with less eye movement, i.e. to read word by word you have to be able to see whole word at once (so your brain recognizes word with 1 lookup, not letter-by-letter lookup) whether this helped - I don’t now but that spreeder says that I can read more than 1500 wpm on casual texts (when there is a lot of material I want to realy comprehend, ofcourse it is slower even by factor of 3)

I have no idea what speed I read at but it's weird seeing this stated... I never imagined anyone but a 4 year old would do 1 and 2 and would have thought that 3 and 4 were basically just normal adult reading. I did read a lot when I was a kid

It is a normal transition for childhoods filled with reading. I read about 10k pages a year until I graduated university.

For a hacker, it is normal to not subvocalize.

I think it is also one of the reasons that we hate meetings so much. An email can be written at about 40 wpm, and read much, much, much faster. So past 2 or 3 people, the dominant strategy should be text, unless sidechannel meaning is needed (where emotions are involved or whatever).

"1) not saying words with inner voice"

That's been debunked a while ago. There's no such thing. http://en.wikipedia.org/wiki/Subvocalization

I wasn't skeptical at you saying the increase was this big, and then I went to try it for myself. Wow. This definitely allows my eyes to track better. I'm a bit dizzy now, too ... Reading felt as fluent as my own thoughts.

when i read that fast i dont have time to think about what i read. thus the colors just disturb me as well.

I don't think they're claiming this as a "speed reading" product in the traditional sense. They're saying it increases reading speed when reading the way most people do, which is line by line. It's certainly not likely to be useful for the kind of reading where you need to scan. But for fiction and other writing that is meant to be read linearly, the claims they're making seem plausible.

What it doesn't help with is transposing from adjacent lines when reading the middle of a column, which happens to me all the time. The middle of the column is always black, so there's not much of a cue to keep you on the same line.

In making my workaround to get a similar effect in calibre, I made a variation I much prefer which cycles red->green->blue, so that column centers are always easy to separate.

That's a good idea. I have the same problem with fiction, for some reason--except for Nabokov. His books are written so well, each line just flows on to the next.

If you're curious, this is what the end result looks like: http://i.imgur.com/NURV2N3.png, and if you use calibre, here's the CSS: https://gist.github.com/osuushi/6461324

You can change the font size and line height by a little bit without needing to adjust anything (since the color gradient is continuous vertically, it is a bit tolerand), but if you make a dramatic change, you'll need to adjust the background height from 72px to the height of three text lines.

I suspect that there's a threshold effect going on: if you naturally read faster than a certain speed, certain design tricks will actually make you read even faster. If you naturally read slower, then those same tricks slow you down.

Would love to see it confirmed or falsified.

(As a note, I am probably under this hypothetical threshold; I'm not a slow reader, but I find that efforts to speed up my reading speed generally push it down instead.)

I cannot understand why it would slow you down, why do you think it might?

Anyway, my experience from this is that it was much easier to differentiate, parse, and scan with the ugly colours (43% faster apparently). However, my natural slowness in reading is in both understanding and committing to memory. I get the feeling that this did not help much with regard to this..

I cannot understand why it would slow you down, why do you think it might?

For me, I found the changing color to be too distracting. My eye was constantly being drawn away from the text I was reading to another color on a line below or above.

It may be worth noting that I only have one eye, and it's not a very good one - 20/100 visual acuity with about a 15deg. visual field.

Amazing, it had the exact polar opposite effect for my eyes. I often have trouble keeping my place in black and white text. I find it like trying to focus on a single conversation in a pub but I end up hearing everyone at once.

If you don't mind me postulating, I wonder whether this difference is something intrinsic to the focussing effect of binocular vision, or if your field of view has maybe trained your brain to be more urgently perceptive to peripheral vision?

then again, maybe its just colour perception.. or different strokes (and thanks, I just learnt about binocular summation.. fascinating)

I slowed down considerably as well. I found myself rereading the same lines over and over for no apparent reason. After a very short time I started to get a mild headache as well. Of course, that could also be the fact that it's getting late but I usually read for 30 minutes before going to bed.

I think it depends how close the text is too, and how long the sentences are on a single line. If it's heavy reading then you don't necessarily want to be or able to read as quickly, though might be good for skimming it.

I don't understand why you'd change foreground colours instead of background colours....

Either way, quick experiment shows it to be horrid for me.

There's an existing, broadly used method for solving the line transition errors - you background color every two lines in an alternating set of colors. There used to be ribbon-feed printer paper pre-colored with this for certain applications that involve reading across lines a lot (like database output.) Seems like that is a more practical solution.

Here's what I mean: http://www.stationerytrade.com/upfile/images/big/20122221112...

What about using eye tracking? A device could just detect you're at the end of a line, and put a small marker at the start of the next line.

I'm not aware of eye tracking setups that are reasonably priced and that accurate, but I like the idea quite a bit :) I'll have to test it out some time - should be relatively fake-able by just moving a marker up/down with keys.

I thought it was every three lines, but yeah.

I think you're right. It's been a few years since I saw one of these in person.

Here is a quick hack that does line-by-line background colours (excuse any crappy code; I'm not a web developer). http://jsbin.com/avuku/166/edit

I was actually surprised at how good it was for linear reading - i.e. reading everything without skipping or missing any line. I'd use it for things like contracts and important tutorials/ebooks, where every word counts.

But I agree that it sucks for quick scans - the different colors just add another layer of complexity for our brain to process...

A research lab at a well-known university has a study underway.

Feel like sharing a link?

Still not public, sorry!

I found my eyes 'jumping' from word to word. I didn't miss any, and I went to the correct lines, but I did seem to be reading at a much slower clip. But that's from spending 30 seconds reading the webpage, so not very scientific.

"Jumping from word to word" is a pretty slow way to read - "speed reading" involves chunking blocks of words or even entire lines - if you watch some people when speed reading their eyes don't scan left-right at all, but just stop briefly on each line as they scan down the page.

I felt (without experimenting in a measurable way) that particularly the blue-red transitions _really_ slowed down my "normal" reading…

It might not be a problem for you - it isn't for me either - but many others suffer from this problem. My other half struggles to read because she has so many line transition errors. And she has to spend all day reading. I see a huge market for this.

But how you make money? Whatever they believe is patentable, I don't see it holds in the court. Good luck patenting colors of text. Further, the major places where you would see this going major: schools, libraries, law school, law field, etc, most of those places are extremely reluctant to new technologies. To them its not a matter of doing it better, its a matter of doing it the way we know how to do it and been doing for years. Lots of libraries still use typehead machines because those in charge are very old and don't trust/hate technology.

It doesn't have to make money. Sometimes people do things for the benefit of others :)

edit: although in this case, they have a patent pending and apps in development, and are offering licensing agreements.

Perhaps you would benefit from a scheme where each word were assigned a standardized color based on its hash.

For large blobs of text, I wrap around to the wrong line often enough to be annoying. However, I found that highlighting my spot and re-highlighting every 5 lines or so solves this problem.

Regarding your scanning approach. An idea I've had is to format each word based on how common it is.

I did find it easier to read faster, however I do believe the JFK portion was chunked with a lot of bigger words/data like years, cities, full names whereas the SBA paragraphs were simpler (IMHO).

The reading test is randomized—different people get different stories in color or black. The order of black/color is also randomized. It's not perfect, but it'll have to hold us over until the larger study from the university research lab is completed.

Would be great if they could A/B test the text used. I found the JFK portion harder to read/understand and I don't think it was entirely the colouring.

Still, I think it is a cool idea and will give the bookmarklet a try for a while.

JFK passage was definitely harder to read. Even so, I got:

"It looks like BeeLine didn't improve your reading speed this time through."

Interesting. I got 5% improvement with BeeLine.

At first glance: wow that's ugly.

Then I read it. Fast. Consuming nearly at a paragraph at a glance when I usually can digest only a fragment of a sentence up to a couple of sentence.

It's not attractive, but it is clever and innovative - well done!

I had the exact same experience. I felt like I was flying through the paragraphs.

It said I had a 15% increase. not too sure about that, but one thing i definitely did notice was that was I kept reading the beeline sentence my brain was 'remembering' what I had just read.

I 'constantly' have to re-read entire paragraphs because I realised I've looked at them without really taking anything in. It was really strange to feel like i was processing the text as I was reading it.

I found it distracting...

I'm initially inclined to dismiss this as ugly and distracting, especially with the default colors being very similar to the traditional link/visited HTML colors. It would be worth exploring further if the claimed improvements are true.

I'd especially be interested in exploring ways to incorporate this into better designed color schemes so that it doesn't look so much like a unicorn vomited on the page while preserving the benefits and usability.

I'm also less inclined to dismiss improvements like these after misinterpreting the occasional email from colleagues lately. I don't know if it is assuming I know the full contents from the 3 line summary on mobile devices, processing too much email, or simply not paying enough attention but I've had to slow down and make sure I get things right.

"Nice" colorschemes are probably less useful here since nice usually means harmonious. The point is to maximize your brain's ability to unconsciously distinguish them, so red/blue is a good choice if you need a lot of help. If you're more sensitive to colors, then the grayscale is probably a better choice.

Two colors can contrast while not clashing aesthetically.

Yes, I figured that was kind of the point of syntax highlighting in code.

An alternative bookmarklet would be to apply the gradient to the line your cursor is over, and just move your cursor at the pace you read lines.

that would be very annoying when reading on any touch based device. Even on a normal laptop - most people who can read well enough dont need to follow the text with the cursor anyways .. its just adds an unnecessary action that would work against the goal of this concept - speeding peoples reading up!

This is a great idea, a subtle mix of the gradients and some readers' select-a-few-lines-at-a-time habit.

Or, to mix in another idea (from philip1209) downthread: have the hover-effect add color-matched dots (or other glyphs) at the corresponding line-ends, currently under the pointer.

For me, that'd be completely unworkable.

Moving the mouse/cursor down the page line at a time to read? _Seriously?_

Applying the gradient when you select text might work. For some reason I already have a habit of obsessively selecting text when I am reading, and I've seen other people that do it as well.

Adjusting to something like the "Blues" color scheme seems to make things a bit nicer.

What I'm worried about is comprehension.

>A study designed and carried out at Stanford University showed an average reading speed increase of over 10 percent for first time users of BeeLine Reader. Many seasoned users experience speed increases of 25 to 30 percent!

So why isn't the study linked?

Regardless of whether or not the claims are true, who in the hell decided for red and blue for the demo's default? The blues/grays themes look okay. IMO, saturated red and blue and probably the two worst colors to use together in a design.

I took their test and came out 2% faster (likely statistical noise more than actual improvement). Regardless, I attribute the improvement to the obscure content in the non beeline reading passage.

I'm curious what others experienced?

I had a similar thought when I read the texts. The first (b&w) text was just harder to comprehend due to esoteric words, lack of thought direction, and several personas. I couldn't understand what author was trying to say. The second (colored) text was about a female teacher and had a common vocabulary and a straight-forward theme with one character.

According to them I read 11% faster. Although I guessed on 2 out 3 questions, compared to knowing all 3 from b&w text.

Thus, I call BS on their testing experience. These two texts are way too different. And picking an easier one for beeline text does a disservice to this hopefully legit fast reading method.

Actually, the test randomizes which passage you receive in which color. So if you got the "harder" one in Beeline, you might have the opposite experience. (I've tried it a couple times to see how it works...)

I did the test and came out 37% ahead. I was surprised.

That said, I often find myself fiddling with the cursor to mark my place when I'm reading something long, so the idea that extra indicators of place might help doesn't surprise me.

I feel better line spacing might also help - their test seemed to have the lines pretty tight together, although I'm not surprised a test would be designed to best showcase their software.

The first time it showed me 15% improvement and I got suspicious because I thought I had read the black text at about the same time.

Then I took it again with a different subject but I timed it.

It took me ~81 sec to read the colored, ~92 to read the black. It said I read 23% faster with BeeLine. What gives?

The passages do not have the same number of words, so just looking at the number of seconds isn't sufficient. You have to use the word counts for each in order to get the words/min.

With a sample of that size there is no way 2% is significant. You're talking about 1 or 2 seconds right? Mine was 50% or more. Maybe I'm extremely distractable.

I had basically the exact same experience. I'm a bit dubious about whether this actually helps on a computer, since I can just use my mouse cursor to track lines.

Try it on your phone—many people find it to be most useful there.

The bright color scheme was selected so that it's really obvious to first-time website visitors what's going on. When we read with the bookmarklets, we don't use the bright color scheme—usually it's greyscale or blue/purple.

It looks like BeeLine didn't improve your reading speed this time through.

i found the colors to be rather distracting and not helpful. the results of two tests taken seem to agree with that.

I was ready to call B.S. on this but after actually seeing it in action, it seems very reasonable. I wonder why this hasn't been done before. I happen to skip lines very often, I'll definitely try this out.

EDIT: Some feedback after reading a Cracked article with it.

First of all, since the inception of the Readability bookmarklet I've always read online articles with some kind of tool (I started with Readability, then passed to the Safari version and now I've been using Clearly for quite some time and I'm pretty happy about it) and now I'm so used to it that if a particular article doesn't render properly, I just straight out don't read it. The first thing I noticed is that the coloration is applied even to single-line titles, I would do away with it and (maybe) apply it only on multi-line paragraphs' titles. The other thing that irked me is that small images are put on the left side instead of being centered, even worse is the fact that text appears on the right side of the images; I would follow Clearly steps in this regard and always put the text under the centered images. Lastly, I would reduce the text area to 600px of width or better yet, dynamically size it so as to accommodate around 60 characters. As far as I can tell, you totally nailed the font size.

I tend to skip lines or re-read lines when reading, and I was surprised at how applying this gradient helped me continuously read their homepage. Definitely going to see how I can use this to improve my reading comprehension!

Thanks for the thoughtful feedback—we are talking with Evernote about Clearly integration. They have a great platform and we hope to integrate with them soon!

I would also love to see Clearly integration! I use it for everything, and you don't need to fuss with background colors or anything.

Please give more options for colors and gradients. I'm sure everyone has different tastes and habits.

Others have pointed this out but: "BeeLine Reader is a patent pending technology" Well, there goes any respect I might have had for this. It is not obvious in every respect, but this is such a basic idea, trying to control it for 20 years while people perhaps find it useful and build this feature everywhere is absolutely destructive. I hope their patent is rejected.

FWIW, I liked it.

Although it is fair to have an opinion about this based on personal experience, remember that performance when reading is a personal matter (anecdotal evidence: the crowd that highlights text for reading [1]; scientific evidence: dyslexia).

So it is good to remember that it might or might not work depending on the way your individual brain works, independently of what the person next to you gets from it.

Having recently looked into speed reading a bit, this seems to do a quite good job at filling the role of a pacer without actually requiring any manual interaction by the reader. Nice work! Easily beats trying to pace yourself with the mouse cursor or text selection at least, while actually preserving pages mostly as-is.

For some reason the color gradients changed the intonation with which I read it--so the whole thing sounded, in my mind's ear, like an eighties valley girl, replete with uptalk, aka the "moronic interrogative."*

"BeeLine Reader is an exciting new technology? That helps people read faster? On computers?"

Maybe I'd get used to it. But if not, a 100x speed increase wouldn't be worth having that in my head. Like, all day?

* http://en.wikipedia.org/wiki/High_rising_terminal

Wow, It feels like the first time I tried glasses. It completely removes any chances of me missing a line. I have a low dyslexia and this just works. Thank you !!

I prefer it to the dyslexic font, it feels less disruptive. It should come bundled with every os :)

My gut feeling (and the websites I enjoy reading, and what I recently did to my blog) is that line skipping is due to too long lines combined with little font-size and line height. But of course, not all eyes/eye-brain systems work the same, and I'm sure this will be more helpful to some than larger fonts with larger line heights.

I very much agree.

Line height, line width, and font size, are the 3 elements of a body of large text that must be balanced. There is some basic arithmetic to this, and it appears everyone seems to ignore it. (HN's design is a perfect example of the 'meh' attitude toward readability.)

I think this article does a good job of visually explaining this balance and how to accomplish it: http://www.pearsonified.com/2011/12/golden-ratio-typography....

Heh, read it (it's in my Instapaper for some future referenc since it appeared first heree) But when I did the redesign I just went with the flow and what I saw nice on my screen. After all, what I write in my blog works as future reference for me, too :)

The testing methodology is quite flawed (at least for the reading speed test on the site). It asks you to read a passage with BeeReader to start out. When you're done, you're presented with questions about the passage before reading a non-BeeReader passage.

The catch is, you will almost certainly read the second passage slower than the first, since you're now looking to retain information for the questions!

The colored passages _feel_ faster, but I'm not sure that counts for much.

My test presented the non-BeeReader passage before the BeeReader version, so there's definitely some randomization going on.

Perhaps the aggregate A/B numbers make a more compelling case for using BeeReader?

I wonder if the color combo choice has any affect on the speed/comprehension of the text.

Actually, the test randomizes whether you get black&white first or Beeline first.

It did tell you it was gonna ask questions. Anecdotally I read the second paragraph faster because I had an idea of the difficulty-level of the questions involved. (ie not very)

I read a lot and I read really fast too. So line skipping is a problem, especially on longer lines.

This thing combines the old Readability bookmarklet with the gradient. I saw the improvement right away, following the line is much easier now!

tl;dr - this is awesome!

It's ironic, you double spaced your sentences. Maybe, that's the answer; More authors should double space?

"It looks like BeeLine didn't improve your reading speed this time through."

Why not show me the stats? I'd like to know, even if it doesn't confirm what you want it to.

Surely the author is not claiming that putting color on text gives them som sort of patentable intellectual property? If this takes off and people will start incorporating this on their blogs, this company will become one of the biggest patent trolls.

Yikes, harsh crowd here. So many people demanding scientific studies to back up the website's claims.

Better idea: Chill out. Then take 1 minute and read some stuff with it on. If you think it feels better try it for longer if not move on with your life.

No has claimed to cure cancer here, just that formatting text differently might give marginal increases in reading speed.

It's not that clear-cut. There's a real reason to ask if there's studies here, because it's not easy to self-assess if this actually works. Reading is more than just "how fast can I scan the lines in order" - it's also about comprehension, eye fatigue, etc. All of which are hard for an individual to assess casually.

I think this is interesting, but I'd want to see studies on what the incremental cognitive load of "color matching" (not something I'm particularly great at) does to reading comprehension, and what the impact of this is on how much I can read in a sitting. It's no good if you read 50% faster but tire out 3X as fast.

I totally disagree with this sentiment (respectfully, of course). If you know the numbers it will bias your experience. You need to try it for yourself and determine on an individual level if your comprehension/speed suffers, improves or stays the same.

Your self-assessment of your subjective experience is notoriously inaccurate and biased in particular, predictable ways.

I'm saying that regardless of whether you know the number or not, you're probably unable to assess the impact of the system simply via personal trial. E.g., one person can't test reading speed or comprehension on the exact same body of text with both methods, for obvious reasons.

Anyone else the numerous AOL chat plugins that used to do this back in the day? e.g. http://www.tpasoft.com/fadeit/

Prior art...

BeeLine Reader applies a color gradient to text that helps reduce "line transition errors" [...] This increases reading speed, particularly on mobile devices that have small screens and short lines

Err. Line transition errors are common on mobile devices, not because lines are short (the shorter the line, the less common line transition errors are), but because people are usually moving, walking, etc while holding a mobile device.

Short could refer to letter height, not line length.

So this is obviously a problem, right? We had MagicScroll [0] which got a ton of positive hits, and now this. I believe there have also been a few other attempts along the way as well. The crux of the issue is velocity+comprehension.

I don't like magicscroll because of the way the lines scroll down; I find it disconcerting. In the case of Beeline, I can't stand the color scheme.

The goals of both software are admirable and I'd love to see more work in this space, but I don't think either of them have it exactly right. If the designer is on here, consider using an interior design color picker website[1] to find a color scheme that works better than the current one.

In short, this is a problem and it would be valuable to somebody like Amazon if it were polished, IMHO.

[0]https://chrome.google.com/webstore/detail/magicscroll-web-re... [1]http://colorschemedesigner.com/ as an example.

Thanks for all the suggestions, everyone! There are two reasons that the color scheme on the front page is so bright (and to some folks, ugly).

First, we wanted to make it really obvious what's going on, and if we'd used a subtle color gradient, it wouldn't have been as obvious. We realize that many/most people won't ultimately use the bright color scheme for one reason or another.

The second point is that people perceive color differently, so what is bright to one person may not seem so bright to someone else. There tend to be age-related correlations/causes here--it's why old people tend to wear lots of bright blues. To them, the blues don't look as bright. What we've found is that younger folks tend like the more subtle colors (eyes are more sensitive) and older folks tend to like the brighter colors (because they can't perceive the color difference in the subtle schemes). We anticipate rolling out our product/feature with a color picker palette so that users can choose the right color scheme for their visual physiology.

Thanks again for all the comments and suggestions, and please feel free to email us through the website if you have an app/site that you'd like to use BeeLine with. We have some code that will make integration pretty easy.

Bug report: try using the bookmarklet on this: http://docs.oracle.com/cd/E17236_01/epm.1112/readme/hss_1112...

It shows only the first paragraph.

(I know, I'm a sad person, but that's the sort of text-heavy doc I have to read all day).

I definitely noticed that I could read faster with this. And the colors were super obnoxious, so grayscale was my choice. What I would really appreciate was if it could be done without taking it out of the page I was already on.

I would really appreciate some way for it to automatically do it and not take me to a new page, maybe something I could install into my browser?

We are absolutely working on more native implementations. This is just the first iteration!

What about a JavaScript version sites could use as a library? (My personal website is text-heavy and might benefit from a very subtle version of this, but I can't A/B test a browser extension.)

Get in touch with me through the email link on the website. We have code that makes this easy.

Loading external scripts each time isn't secure.


I am a voracious reader and I read pretty fast(never measured it though), and this really sped up my reading a lot. That was impressive. But "patent pending" ? Like someone has already pointed out here, patents like this are destructive and I too hope that it is rejected.

You can also reduce line transition errors by increasing font size and line spacing. The font in the "What is it" paragraph is, to my eyes, too small and tightly spaced to be easily readable (perhaps purposefully, to demonstrate their value).

That's probably the point: Beeline makes it easier to read more text on a small screen. Increasing font size and line spacing doesn't work well on a smartphone, much less a smartwatch.

I think the line spacing and line length matter more than the font size. With these high-resolution displays, the fonts can be pretty small, and they're still readable, but you then need to make the column narrower and add a couple pixels to the line height.

It works fine, it just creates a bit more scrolling.

Completely agree. I couldn't make sense of the gradient deal, but open up the inspector, set the body font size to 16px and the paragraph line height to 150% and it all becomes a lot clearer.

I am dyslexic. I just used the screen reader on the iPhone to read to me the challenge text at full speed. It told me that I read 4% faster with BeeLine on :) apparently the iPhone cares, because I wasn't even looking at the screen.

Insidently, the speak function of iOS is amazing for people with dyslexia. I use it all the time to listen to text at speeds of 300+wpm. I know many of my friends can read at 600+wpm my them selves, but not for a few hours on end. In any case, if you are dyslexic and use iOS, check out the read function under accessibilities.

I find this incredibly hard to read, my eyes feel like they're being pulled to sudden colour changes. I find this extremely difficult to scan, as well.

I could see people licensing this as a mode in apps, that is ... you hit a button and all the text changes to use this color mode to allow you read through things faster. Then you can turn it off if you want to read things a bit more leisurely ... and yes, it did speed up my reading, not sure if that's a placebo effect or actual.

Isn't that why proper typography establishes line width limits and a bit of space between each line? That always made it a lot easier to "know where I was"...when I could see the beginning and end of a line of text without having to move my eyes.

The bookmarklet wasn't working for me on Chrome (permission errors), so I threw together a Chrome extension with the highlighting code: https://github.com/egonSchiele/beeline

There's already a Chrome extension from the Box.net 2012 Hackathon:


I tried it but it didn't work very well for me. It tries to do some readability-esque stuff and doesn't do a very good job. I'd rather just have the coloring with the rest of the page as -is, which is what my extension does.

A big pet peeve of mine has been the trend to forgo black fonts for lower contrast grey, and it appears this developer is doing that as well (#333 instead of #000 when "Off" is selected). My hunch is that low contrast text (I've even seen medium grey on light grey!) comes from designing on a fantastic display with 100%+ color gamut and great accuracy and viewing angles. Take a phone/tablet/laptop with an average (lousy) LCD into a brightly lit room (or God forbid, outside) and the contrast goes in the toilet. Is black on white that hard?

The other problem I see (mostly on Chrome) is that headings are anti-aliased, but the body text is not. The difference is subtle, but still noticeable.

When speed reading, this doesn't seem particularly effective. Perhaps a dot at the end of the line with a particular color that corresponds to a dot of the same color preceding the following line would be better for those who minimize eye movements.

Installed, tested with a couple of articles. It does the job it claims to do.

A few things: it would be nice to be able to configure the plugin to limit the color variations. I'd like to try with only 2 colors and with less drastic contrasts. I suspect that only a slight transition between two close colors would already be helpful enough for me.

Now, I'm afraid to get used to the crutch and find it harder to read books after. After using vim to edit almost anything, I have developed the bad habit of pressing ctrl-[ to go in normal mode any time I'm in some text editor, be it in the browser, email client, word processor, whatever.

We absolutely plan to make configurable versions available—this is just the first iteration. As for your concern about extended use: the only thing we've heard so far is the precise opposite. People have contacted us to say that they experience a "training effect", so to speak. Apparently reading with the color gradient helps them read in black for some period after. Would love to know how it works for you—feel free to contact through the email address on the website!

I find myself selecting text every now and then to make it easier to read. On the examples on BeeLineReader's website, I was surprised I didn't have to select text to read it.

The examples in the bottom of the page really helped me realize how much this helps. Seriously, I read those paragraphs with the "Bright" theme and then I read them with BeeLineReader disabled ("Off") and I could notice my brain working harder.

I realize it looks ugly as other commenters have posted before, there's probably another method that doesn't make the text look so "ugly".

That page physically hurts my eyes to read.

Anecdotal, but I also got started to get a headache reading that page. Had to close it.

I would pay to get a PDF version of this. I read PDF documents all the time.

This. I am a lawyer. I read hundreds of lines of dense fine print every day. It is quite possibly the worst part of my job.

Me too.

Interesting concept. Do they have a research paper out describing the results in more detail?

A couple of problems: 1) beelining doesn't work well with links in text 2) Doesn't work on Hacker News at all.

I tried it on HN as well and the same issue. Otherwise looks as a great idea!

BIG thanks for not lying to me after I didn't perform any better reading the colored text. I would definitely consider showing the colored text first for some others, and second for others. Once I knew that you were going to ask questions about the text, I became more attentive. Nonetheless, I tried to read as if I didn't know there would be questions afterwards in hopes of not skewing the results.

Once again, thanks for being honest in your test and not convincing me to use something that might not actually help me.

Any plans to make this available as a plugin for ebook readers?

We're in early-stage talks with some companies in the ebook space—DRM obviously forces us to deal with the owners of various walled gardens. We'd love to find a popular, DRM-free, ebook platform. Suggestions welcome!

Is this based on open research or is the idea of gradients over text itself the patent-pending invention?

I'd love to integrate this with my iOS speed-reading app (http://velocireaderapp.com). Any interest in collaborating on a spin-off iOS app, to read, say, DRM-free ePubs? My contact info is in my profile.

I don't know if he's around here, but you should get in touch with Patrick Thompson at Inkstone Mobile (http://www.inkstonemobile.com/). He has been working in this space for some years and did a wonderful presentation at MicroConf 2013 (http://mobileportland.com/events/adventures-app-marketing).

The main one is Gutenberg, but Beeline users can just install it and make it work on the gutenberg site. You could still contact them to get them to add it as a feature.

2 Suggestions:

1. It'd be very nice if you had a version that tweaks text colors and doesn't touch anything else, i.e. just like on the demo page. When I tested your bookmarklet and it tore up the page I thought something was broken. I only found out that it uses readability because I started digging when it 'broke', you never mention 'readability' in your copy.

2. People will want it enabled by default. You can't do that if you use readability.

For your first suggestion, I dusted off some old code and modified it slightly:


It should keep the layout as is, while only adding color, but I have only tested it on wikipedia. The color period is wrong, but it will show you some approximation of how sites will look with a non-interrupting beeline bookmarklet.

I find it awful, as my eyes keep jumping to the color changes, assuming them to indicate some kind of emphasis. Then I have to stop and go, "No, that's not a particularly important word, it's just the Time Cube style they're pushing."

Looking at the text on their site, I suspect (aside from issues like dyslexia) that the real problem is that a lot of people are reading text that's too small and probably has overly-wide lines.

I tried it out for awhile, and it did seem to help me read faster, but I felt like my brain was been strained. If I started doing this all the time, I'm wondering if my brain would freak out reading regular black on white text.

I'm wondering if just adding reference points along the margin or between lines could accomplish the same thing without having to change the text color. Something similar to the tick marks along a graph axis.

This is surprisingly effective and awesome.

I created a (very hacky) style sheet to do this in calibre: https://gist.github.com/osuushi/6456804 . It gets a bit out of alignment when a paragraph wraps to a new column or page, but over all it gets the job done.

Edit: I fixed it to do one color transition per line, like the original.

One tiny bug: in the survey after the reading challenge, I was unable to change the number of hours I read per day. I tried to enter 1.5, but it won't take the decimal and I was unable to backspace to delete the 5.

Overall, a very cool idea, I was surprised to find that I read faster. It said only 3% faster, but I searched for an event mentioned in the first set of text which slowed me down.

Thanks for the feedback! It's not just about speed, it's about reading ease too. We hear great things from people who read while on public transit. All the movement makes line transitions (and staying on the same line in general) more difficult.

WOW, I just tried this on some text and although I think I'd need some more objective tests, it FEELS faster, like significantly so.

I've just learned something about how my own vision works.

Apparently, when I'm reading on screen, somewhere towards the middle of the line, I switch my focus from my left eye to my right. This makes it obvious, because with the color at the end of the line, I switch too soon, and miss the third of the line in the middle.

Possibly this is a consequence of wearing glasses.

I really enjoy using this. While people seem to dislike the red and blue default, I enjoy it. I am not a big fan of the colors working together but I feel like it works the best for it's intended functionality of the choices you made available. I think this might make reading some things considerably more enjoyable for me. Thanks!

A different approach but also bookmarklet

Interesting, thanks!

This has been around for a little while, hasn't it? Like, a year or two at least? I'm reasonably sure I've seen this website before...

Not to say it's not interesting / not a valuable submission. I love the idea, and it seems like it might help me read faster, which is always cool. Just wondering if my memory is correct.

Good memory—we have been around for a little while. I waited to do a Show HN until we got the website revamped earlier this summer. The web work was done by a couple of freelancers that I met through a HN freelance post, as it happens. The HN community is awesome, and it's great to bring it full circle!

Hmmm. Is it possible to try this: Make a version that creates a black to grey gradient for every sentence. The beginning of every sentence starts out black and gradually turns grey at the end of the sentence. Then try it switched. Make it start grey and turn black. Test both.

Just wondering what the result would be. Out of curiosity.

Personally, I am not a fan of this "reader". The changing color is a distraction to my reading experience. The scheme I found the least distracting was the "Gray" scheme. But, I am not someone who would use it. Interesting concept though - I hadn't thought about it earlier.

PS - I am a voracious reader.

I completely agree. I tried the test in dark and then grayscale, neither time was an improvement over black text.

I was really surprised to find myself enjoying using this. Great work! Taking the test really emphasised that it's not only faster, it's also "easier" to read. I used the Dark colour scheme, as it was less distracting than the bright default one for me.

I learned to speed read years ago, and this breaks that for me. One of the keys with speed reading is that you don't read every single word. With this I was reading every word. It felt slower and tiring.

The test said that it did not improve my reading but didn't say why.

I wonder if the test tells you when you read faster without it. Subjectively I feel that I did, but the test just returned "No improvement with BeeLineReader"

I suggest avoiding bright blue in your default colour scheme for beelinereader.

The reason is because it matches the default colour for links. I wouldn't be surprised if many people tend to read linked text a bit differently.

Have you thought about using colours like orange, green, purple?

I did History, used Bright, and got a 43% improvement.

Then I got suspicious. I thought that I was subconsciously affecting my own behavior. (Anticipating a test, for instance. Expecting Beeline to speed up my reading, for instance.)

So I did Nature, used Bright, and got no improvement.

...I need a better blind.

Could work. Look at how kids read initally, they use a ruler to keep track of what line they are at. Even some teenagers do this or adults with dyslexia.

I wonder if it would hamper your normal reading abilities if you start reading like this most of the time from young age.

Colored text is often associated with links in the context of HTML...what about striped backgrounds, as is commonly used for table rows?


I don't know about you, but I'm really reading faster. And that's because I'm only reading the red text. I just realized I skipped all the blue content, and don't have a clue if anything useful was written there.

I like this a lot, but unfortunately going to various news sites (NY Times, Slashdot, etc) it seems like the bookmarklet failed or complained it wasn't designed for the home page (in cases where it wasn't a home page).

I find it counterintuitive that this helped experienced readers more. It didn't make a difference for me in their test, and I read constantly. I would suspect this line coloring would help a less experienced reader more.

I... I wasn't aware this was a problem.


It is a problem, especially for beginning readers who struggle to comprehend as they're reading and don't have the 'bandwidth' to parse the incorrect sentence and find their place in the text on the fly. Stressful situations (tests, public reading in front of the class, etc) likely make this worse.

Well, this looks interesting, but doesn't work with HTTPS. Which is a problem.

Add underline to links (many sites identify them only by color, link "disappears" with beeline).

Awesome marklet! Is the source available? I'd be happy to fix this issue up myself if it's in VCS somewhere.

I tried their test and had no improvement in reading speed. I also use my mouse to read on a desktop (highlight end of one line and start of the next) as I go, so I think this product is just not made for me.

Ever try reading on a phone/tablet while riding on a subway car? Might be worth it there!

For some reason i found myself calculating the patterns of blue, red and black and if words like 'the' 'and' always fall on black or red highlights. I guess that slowed me down big time.

I could see this working, I tend to read slower with black text maybe because I lose track of where I am during the page. The downside is this hurts my eyes and makes me dizzy because of my computer screen.

It's funny that so many commenters are complaining about the lack of a linked study. It's as if people are incapable of independently analyzing the claims and reaching their own conclusions.

Easier to read line by line, perhaps. But certainly much harder to skim. If you wanted to skim a paragraph at a time as I often do, the artificial emphasis created by the coloring throws you off.

well, it significantly mangles things on The Guardian. basically, all of the little "NSA" tags in this article: http://www.theguardian.com/commentisfree/2013/sep/05/governm...

get wiped out, making the text difficult to understand.

Also, be careful to wait for it to work. I didn't think it worked and clicked it a second time. I ended up with funfetti colors, not smooth gradients.

Also doesn't work on the NY Times. For example, none of this article's text displays after clicking the bookmarklet: http://bits.blogs.nytimes.com/2013/09/05/americans-go-to-gre...

I smell a conspiracy!!!!!!!!!

I was skeptical, I took the test, it said I was 23% faster on the fiction, so as much as I think it looks a little ugly, if it really is that much faster, then it's worth it and clever.

Have anyone viewed the generated DOM tree? It looks like every single letter has a tag around it, which will make it painfully slow on older computers if you have a pretty long blog post.

It already makes their homepage very slow on my Surface RT. Colors appear only after several seconds and IE 11 is asking if it should continue or stop the long-running script all the time.

I like the effect, though. I hope they can optimize it technically.

It's iOS 7 for text!

Seriously though, it would be interesting to see this as a feature in new e-readers. I have a feeling that if the e-ink could support it, the effect could be better than books.

I would like to see a version that does selective highlighting. So it would highlight verbs and nouns, maybe bold famous names and dates, and gray out slightly transition words.

Does the research provide any info about fatigue after using it?

Can I make the obvious comment: it's not how fast you read text, but what text you choose to read.

Reading super fast over the National Inquirer is not likely to be an overall win.

There's one problem I have with it. This afternoon it triggered a migraine.

I just came back just now, just in case it was a co-incidence, and yep, it was not a co-incidence.

Me too, maybe it is the color (blue / red contrast), I know that ~black background with ~white text is an instant trigger for me, always immediately close the tab when I visit such website. Do you see the words kind of "vibrating" when it triggered your migraine?

Just a counterpoint to all the negativity: The increase in speed was instantly obvious for me. Will be giving this a try for a few weeks at least.

For me as well. I'm actually very surprised by all the negative reactions.

FWIW, when I looked the demo, I thought to myself, "Ok, I'm going to try to read this quickly." What was so impressive was how easy that was to do. Total comprehension, less eye strain. Sold.

Thanks for the positive feedback—glad to hear that it works for you! Follow us on twitter to keep apprised of new content/product integrations. There are a couple deals in the works now.

Oh you're the creator? cool. A word of advice: work out a way to sell this to doctors and other people who need to keep appraised of massive amounts of info. They have the money and the motivation to be your primary customer base.

He is. Also, I'm his friend and the original coder of the bookmarklets.

Thanks for the input—great idea!

It's very distracting for me personally. I'd prefer a subtle gradient on the margin to help me keep track of the area where I'm at.

Is it just me or is anybody else thinking that just making lines alternate between colors (think of tables) would do a better job.

Why do we need fancy gradients?

I'll be testing this with different color schemes, but yeah, works!

Addition: for eink readers, would underline or italics work in place of color gradient?

You could accomplish something like this the same way with a "green bar"[1] style of background. That is, the background of every two (or three... I think two would be better but you could test it) lines having a light green (or blue, or since you mentioned eInk, grey) background and then two lines with a normal white background.

[1] http://en.wikipedia.org/wiki/Line_printer#Paper_.28forms.29_... "The paper was usually perforated to tear into cut sheets if desired and was commonly printed with alternating white and light-green areas, allowing the reader to easily follow a line of text across the page. This was the iconic 'green bar' form that dominated the early computer age. " (emphasis mine)

As an academic who has to give a lot of conference papers I bet this would be great for reading off an iPad or laptop without losing my spot.

Aside from the bookmarklet, I love it. Without an extension, though, I don't see myself using it. Hopefully we'll see one soon.

Yep, we're working on it. We have a couple of deals in the works, and we are hoping to get on major platforms.

Interesting. Line skipping is by far the most annoying problem that I face when I have to read after a long day; especially on a screen.

Hideous, but I'll be damned if it didn't allow me to read that page extremely fast. Wonder where this could be used...

Not worth the trade-off, if you ask me. I would never publish something that looks like this. It is very distracting to me.

It's probably not a technology to be used by publishers. It seems like more of a reader-level technology. A browser or ebook reader/app feature.

The examples are a bit short (line length). It seems to be more useful with longer lines, and confusing with short lines.

I remember seeing this at the Box Hackathon a year ago but couldn't find it online. Thought it was neat. Congrats!

It doesn't make me read any faster and I have the feeling I pay less attention to the content. Am I the only one?

As an author/programmer I would love to see a LaTeX implementation... (If only there were more time in the day)

Let's say it this way: If you actually profit from a 20% increase in reading speed, then you read way too much.

Totally reminds me of the days when Yahoo messenger was used, and they had that fading, gradient text. Super cool.

Nice! Can BeeLine be made to work with MagicScroll? Currenly if i click one bookmarklet the other one breaks.

I created MagicScroll.

BeeLine doesn't detect line breaks.

Instead it puts a span around every character and sets its color manually.

Anyway the individual spans cause issues for MagicScroll but it should be relatively easy to retrofit MagicScroll to add the beeline gradient to each line.

Very interesting. Gave it a bit of a test run and it felt good. I'm definitely going to try it out.

I'd be interested in something like this being used in a e-reader app like Kindle or Aldiko

We're talking with Amazon, and we'll get in touch with Aldiko! Thanks for the suggestion.

Love it.. Never install extensions, but will install this one.

Not usable for sites, but very much so for articles

This actually strains my eyes quite a bit, but that's just 1 personal sample.

I tried it and it actually felt quite easier to follow along a line of text.

I wonder whether this has an effect on eyestrain or reading longevity.

Red & Blue are sure good for your eyes! Professionals at work.

Wow why don't they use this idea in printed books as well?!

Is there any scientific evidence supporting this?

Note to author: does not work on medium.com

Thanks—the bookmarklet is just a first step. We are looking forward to integrating with lots of platforms, including medium.com, which we read all the time!

I actually read everything on that page.

can i get this as a firefox extension?

We're working on native integrations, and we realize the bookmarklet is a somewhat kludgy first step. Thanks for your interest!

I can't believe it but it is faster and more enjoyable to read with the gradients. I can't get the bookmark to work with firefox. Extension would be great!
