About GBrain
GBrain gives a person or team one shared memory across AI tools such as Claude Code, ChatGPT and Cursor. Notes are stored as plain markdown files you can read, edit and export. Connected accounts like Gmail are linked once, with activity logging, and team workspaces share one thread. It exposes MCP and CLI, and core code is open source on GitHub.
