OzBrain

Working across several assistants means carrying the same brief by hand: paste it into Claude, paste it again into ChatGPT, drop the file into Cursor, then update one copy and let the rest drift. OzBrain keeps that material once and exposes it as an MCP connector at ozbrain.com/api/mcp, so Claude, ChatGPT, Claude Code, Cursor, Gemini and anything else that speaks connectors read and write the same entries. Knowledge is filed as separate articles under a routing index, which is how an agent pulls only what a task needs instead of the whole store. There are personal brains and shared brains, and collaborators are invited into the shared ones. Signing in with an emailed code creates the account, and the site puts first setup at around two minutes.
