OzBrain
One shared brain for all your AI agents to read and write
OzBrain is a hosted knowledge base described as "the brain layer" — a single shared source of truth that Claude, ChatGPT, Claude Code, Cursor, and Gemini can all read and write. Instead of keeping separate context for each tool, every agent pulls from one brain, so you never explain yourself twice and every session starts already knowing your stuff.
It solves the problem of manually ferrying context between agents: copying a brief into Claude, pasting it into ChatGPT, dropping the same .md into Cursor. That workflow leads to drift as copies update separately across Drive, Slack, email, and Downloads. OzBrain structures what you know so agents read only what they need, with the current version of each article kept front so every agent decides from the same file.
OzBrain is for teams and individuals who work across multiple AI tools and want projects, decisions, research, and preferences shared as current knowledge. It hosts the pattern Andrej Karpathy published for knowledge bases your agents build and maintain, and can be connected in under two minutes via an MCP custom connector.
