iDoRecall cofounder and 67 y/o entrepreneur here. Today’s version of iDR is a total rewrite of our MVP. iDR began as a digital solution enabling the cognitive science strategies that I used to graduate #1 in my med school class back in the analog 70s . iDR takes spaced-repetition flashcards beyond the bounds of well-known solutions. Barbara Oakley, Ph.D., creator of Coursera’s Learning How to Learn , uses iDR for her own lifelong learning. Recently she became our Chief Learning Science advisor.
Upload your learning content into iDR: PDFs, Word files, PowerPoints, images and many other file types. Add videos hosted on YouTube, Vimeo and other sites to your iDR library. Read, watch and listen to your content on iDR.
Create flashcards (we call them “recalls”) that are linked directly to the concepts, facts, formulae or whatever you want to remember in your learning materials.
When you practice memory retrieval with your recalls, if you struggle with the answer, you’re one click away from seeing the exact spot in your content where you created the recall so that you can quickly refresh your memory in the original context where you learned it. Stop wasting time rereading. Read once. Watch once. Listen once. Abstract and curate what you want to remember into recalls and use spaced-repetition memory retrieval to remember everything you learn. Rereading, highlighting and rereading highlight have been proven suboptimal tactics for remembering what you’ve learned .
Metacognition training wheels, Pomodoro timer and project management tools for learners included. Create study groups with classmates and collaborate sharing recalls and content. Teachers can create classes in the app.
We have reference docs on our self-hosted Notion  and helpful videos on our YouTube channel . I write about learning on Medium and Better Humans . Please let me know if there is any way that I can be helpful to you.

Strange that there’s just another spaced repetition show HN just next to this one. What are the odds?
I’m a co-founder of Kenhub and we use some spaced repetition techniques in our quizzes. But it’s quite different still. The bigger difference for us is that we create and curate the content. I’m wondering if there’s some opportunity for collaboration. See contact details in my profile if you’d like to chat some time.
Looks nifty. Is there a way to enter source code(programming) in the editor? I cant find it. The thing I can find is how to enter formula, but that is not what I'm looking for.
Obligatory HN cynacism: I don't think I'll end up using it due to the massive investment I've already made in Anki + switching friction. Plus, it's not open source, so if the service ever went away I would be crushed (which is really important to me since some of my cards have 10y+ intervals).
I think it would be good if the main content appears on the center (I see pdfs showing on the right side of the screen).
Something I didn't like about anything less trivial in Ankhi was that there was a lot of overheard in trying to write a card knowing that I would never reconcile it with its source again. So I would encumber it with context.
FYI - I tried logging in with facebook.
My biggest desire is to create flash cards directly linked to software documentation.
Personally, I gave up and just converted the web page in question to PDF, and annotated from there. Then you get easy document position markers and no changes over time. I would also be very interested in a system that could do proper webpages natively, though.
We do have plans to release browser extensions that will enable you to create flashcards linked to areas of interest in web pages that you are viewing. We will save the URL and a PDF of the page in case the content subsequently changes.
All I want is really Anki with manual intervals. Life would be so good :|
Steps is just manual entry of the first intervals, right? That's very static.
You can choose as many steps as you want, so if all your cards have a single card setting, you can choose the schedule you like once and for all. But I don't know if using Steps in this manner is any good. Just an option.
