Details
GalaxyBrain is an Information Operating System that runs based on local files.
The main features are as follows:
- Local-first structure: All data is stored on the user's device as structured JSON files, ensuring control over the data.
- Dynamic references: Through variables, formulas, and real-time references between pages, it provides a document editing experience similar to a programming environment where data syncs automatically.
- AI-friendly design: Through a built-in HTTP API and MCP (Model Context Protocol) tools, Claude Code, Codex, or local LLMs can directly read and utilize the data in the folder.
- No account required: It can be used immediately without creating a separate account and is provided for free.
