> GalaxyBrain is an information operating system powered by local files. Write like a document, calculate like a spreadsheet. It lives between a note app, a wiki, a spreadsheet, and a task manager — a workspace where computation and structure are built into the page, not bolted on. Your pages are a folder on your computer, and any AI you point at that folder can work with them too.

So a bit like Obsydian or NotePlan but with app in single html file, first class document properties as values and focus on MCP/AI integration for automation.
