A hosted knowledge base every AI agent can read and write, shared across Claude, ChatGPT, Cursor and coding agents via connectors.
OzBrain is a hosted brain that sits underneath the AI agents a person or team already uses, reached through the connector menu in Claude and ChatGPT rather than through code. Knowledge is stored as structured, nested articles carrying links, provenance and freshness, so an agent can pull the exact slice a task needs - the email body rather than the whole launch plan - instead of loading everything and inventing the rest. When newer thinking lands, OzBrain walks back through the existing articles on its own, marks superseded content as replaced and points at the current version, so no agent answers from a copy you have moved past. Writes are staged and proposed before they land, and every change is recorded with the agent that made it, the article touched and the reason, letting several agents work in parallel without overwriting each other. A team points every member's agents at the same brain, so what one person's agent works out is already available to everyone else's. Data is encrypted at rest and sealed to the account, is never used for training, and can be exported as plain markdown at any time, including after cancelling.

OzBrain works by combining 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. to help users with 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..
