GalaxyBrain is launching today. It's an information operating system powered by local files. Pages with variables, formulas, and live connections. Everything runs locally. The whole app is a single HTML file.

I've been working on some version of this for years. It's deceptively complex under the hood. You might find some rough edges on the fringes but the core is solid. There's a built-in API and an MCP tool. Anything you can do in the app, you can do via the API. Point Claude Code, Codex, or a local model at the same folder and build whatever you want on top of it.

A few simple building blocks. That's all there is. But with them you can build complex systems for your information to flow through.

You can keep your brain alive a heartbeat

I'm sure if youre building this youve tried roam, tana, obsidian etc., what prompted building this, what does it do better for your personal use?

Let's go! Can't wait to try.

launch days are the best days can't wait to try it

lets gooo!

So excited to try!!

Good thing there is no link. Someone would possibly want to check it out and if you gave a URL then they would. *Facepalm

hi there, I'm testing it and it says my browser (Brave) doesnt have localStorage? I even downed the Shield for the app, and tested `localStorage` on console, and, at least in console, it works as intended...

sorry joão! brave isn't actually supported, that's a docs error on our end. will fix. they block the file system API. the ws://localhost:1924 is the optional local api. never hits the network, ignore it if you're not using it.
