Show HN: Galaxybrain.com – a JSON-based knowledge system

[j0ncc]

Hi HN,

I’d like to share a project I’ve been working on called GalaxyBrain. It’s a tool for organizing information.

Key features: Embeddable dynamic metadata: as you type, metadata is generated in the background. This metadata can be accessed and embedded directly into the page.

Light programming concepts built in: you can add custom values (think variables) to any page, then reference those values across different pages to build dynamic relationships.

Metadata can be chained together: referencing values on other pages, or by using a formula. Updates to anything flow through the entire system (like a spreadsheet).

It runs on local JSON files: plan is to offer a hosted version, with structured end points for everything so you can use it as a datastore. If you host the json files locally it will be free forever.

I use it to build a model of my life. Everything I care about has a page, each with its own dynamic metadata that updates in real time as things change within the system. Each page acts like a little dashboard for that thing.

The app is pretty sprawling, and there's still some bugs on the fringes. I'm onboarding people slowly and fixing bugs as they come up. I wanted to share it early to get feedback and see if I was onto something.

I really want something like this! Everyone is breaking up existing information to access it later and link back to the source, but no one is making the information actually meaningful on the fly. This is absolutely brilliant! :)

I've been mildly annoyed that every component-based front-end library's Hello World is a counter, with a button to increment the count. But it seems like no personal knowledge management systems have a way to actually embed an arbitrary component like that, with its state. It would be actually useful for games and counting reps in various contexts.

Maybe this will actually enable that?

Wait, this is the same Jon Paul as https://www.instagram.com/jonpaulsballs ... who does amazing things with geometry and hand-sewn spheres.

if it is as shown in the video then i'd pay for it

Refreshingly fresh take on this space. My Notion is bloated, and Obsidian never stuck. Would love to get my hands on this.

I want it and have been trying to accomplish something similarly using Obsidian.md

but, the video looks very promising indeed!

this is what I’ve been looking for. Like a Freeform spreadsheet. super excited to give this a go!

Pretty cool animation on the website

I don't see a time efficient way for people to look at the app and provide feedback.

Good luck.

Eh, your "joint waitlist" does not validate by email (vlad@vlad.studio). Outdated domain validation, I guess
