Monsef Holdings Pty Ltd

Freemium

A hosted knowledge base every AI agent can read and write, shared across Claude, ChatGPT, Cursor and coding agents via connectors.

Key features

  • Connector Setup: Add OzBrain from the connector menu in Claude or ChatGPT, sign in and approve - no code, SDK or installation required.
  • Nested Article Retrieval: Knowledge is broken into nested pieces so an agent loads only the slice it needs, cutting tokens, latency and hallucination.
  • Automatic Supersession: When newer thinking arrives, OzBrain revisits existing articles, marks the old as replaced and links forward to the current version.
  • Staged Writes: Changes are proposed before they land, so multiple agents can write concurrently without clobbering one another.
  • Change Ledger: Every edit records the agent, the article and the stated reason, giving a readable history of how the brain reached its current state.
  • Shared Team Brains: Point a whole team's agents at one brain so context worked out in one person's chat is immediately available in everyone else's.
  • Broad Client Support: Works with Claude, ChatGPT, Claude Code, Cursor, OpenClaw, Hermes Agent, Gemini Spark where available, and any connector-capable client.
  • Markdown Export: Export everything as plain markdown at any time, including after cancellation, with deletion meaning the content is actually removed.

Best for

  • Cross-Agent Continuity: Stop re-explaining the same project context when moving between Claude, ChatGPT and a coding agent.
  • Single Source of Truth: Replace the scatter of launch-plan copies across Drive, Downloads, email and chat with one current version agents read from.
  • Team Onboarding: Give a new teammate's agents the accumulated decisions, research and roadmap the rest of the team already has.
  • Agent-Maintained Documentation: Let agents append findings and decisions as they work, with humans reviewing and correcting in the same place.
  • Rules and Skills Storage: Keep coding standards, conventions and reusable skills where Claude Code and Cursor pick them up automatically.
  • Long-Running Research: Accumulate customer research and competitive notes across many sessions instead of losing them to chat history.
