Somewhere in your company there's a document called "ChatGPT context" or "master prompt". Everyone pastes it into new chats. Nobody remembers who updated it last, and half the team is using the old version.
Company Brain is a governed knowledge base for teams that connects to ChatGPT through MCP. It replaces the pasted context document: your products, terminology, business rules and tone live in one reviewed place and load into every chat automatically, so every conversation starts fully briefed. Update a fact once and the whole team gets it in their next conversation.
Connect in three steps
- Add your company facts. Write them in or upload documents. A human reviews every fact before it becomes shared context.
- Copy your MCP endpoint. One address for the whole company.
- Add the connector in ChatGPT. A few minutes, guided the whole way.
What changes in practice
Before Company Brain:
"Context: we're a 14 person marketing agency in Oslo. Our clients are in retail and consumer goods. We never use exclamation marks in client copy. Our packages are called..." and then the actual request, buried at the bottom.
With Company Brain:
"Draft the kickoff summary for the new retail client."
ChatGPT already knows your package names, your tone rules, and that kickoff summaries follow your standard structure. The output is ready to send, or close to it.
Built for teams, priced per company
ChatGPT memory helps one person a little. Company Brain helps the whole team the same way, every time. Everyone works from identical, approved context, so the intern's output follows the same rules as the founder's. Teams that already built Custom GPTs usually keep them; how Company Brain compares with Custom GPTs covers where each one fits.
Company Brain's free plan includes 50 company facts and one curator, with the whole team connected through MCP, free forever. Paid plans start at €89 per month, priced per company, never per seat.
When your team also uses Claude or Copilot, the same facts follow them there. Company Brain connects to Claude through the same MCP endpoint, and how to stop repeating your company context in every AI chat tells the longer story of getting there. One place to maintain the truth, every AI tool briefed.
Frequently asked questions
- How is this different from ChatGPT's memory?
- ChatGPT's memory is personal and unpredictable. It remembers fragments of what one user said, and nobody else on the team benefits. Company Brain holds facts a human approved, shared by everyone, consistent in every session.
- How is this different from a Custom GPT?
- A Custom GPT lives inside ChatGPT and its instructions are maintained by whoever built it. Company Brain works in regular ChatGPT conversations and in Claude, Copilot and Cursor too, from one set of curated facts.
- How does the connection work?
- Company Brain connects to ChatGPT through MCP. You add it as a connector once, and your company facts load automatically in every conversation after that. Adding custom connectors requires a ChatGPT plan that supports them; as of this page's date that means the paid plans (Plus, Pro, Business, Enterprise).
- Is there really a free plan?
- Yes. Company Brain's free plan is free forever: 50 company facts, one curator, and your entire team connected. No credit card and no expiry.
