Second Brain

Share project memories across AI tools in your own Cloudflare account

Meet Second Brain

Second Brain gives connected AI tools a shared store of decisions, ideas, preferences, and project context. A memory saved through one assistant can be recalled in another, helping work continue across applications and conversations. It supports MCP clients such as Claude, ChatGPT, Codex, and Cursor, with Mac and Windows setup tools.

The software is open source and runs in the user's own Cloudflare account. Memories can be browsed, edited, exported, or deleted, and projects keep related information together. A team edition adds a deliberately shared knowledge layer alongside private memories, so collaborators can exchange useful context while retaining separate personal information.
