GalaxyBrain
Launching today
GalaxyBrain is a local-first knowledge system where pages have variables, formulas, and live references between them. Define a value on one page, reference it from another, and it stays in sync automatically. Like a programming environment crossed with a document editor. Everything is stored as structured JSON files on your machine. There's a built-in HTTP API and MCP tool so you can point Claude Code, Codex, or a local model at the same folder and build on top of it. No account needed.

Hey PH! I soft launched GalaxyBrain here about a year ago. The response was encouraging but it became clear pretty quickly that the foundation wasn't strong enough for what we were trying to build.
So I convinced my smartest friend (@viralplatipuss) to join as technical cofounder and we rebuilt the entire product from the ground up. GalaxyBrain is closer to a spreadsheet engine than a note app, and that level of complexity needed a foundation built properly.
It's ready now. The core is solid. You can have thousands of pages with dynamic values, all connected to each other, all staying perfectly in sync and updating in real time.
It's been a multi-year labor of love. You might find some rough edges on the fringes but the engine underneath is rock solid.
Would love to hear what you think and if this approach has potential.
