Claude Projects vs Company Brain
Projects are one of Claude's best features. The question is what happens to your company's knowledge outside them. Here's where each one belongs.

Claude Projects earn their reputation. Load a project with the relevant documents, set instructions, and every chat inside it starts informed. For a defined piece of work, a client engagement, a report, a product launch, that's exactly the right shape.
Company Brain complements Claude Projects rather than replacing them. Claude Projects hold documents and instructions for one project inside Claude; Company Brain holds your company's approved facts in one reviewed place and delivers them through MCP to Claude, ChatGPT, Copilot and Cursor, so every chat in every tool starts from the same truth.
The trouble starts with knowledge that isn't project-shaped. Your company's tone, product names, pricing rules and strategy belong in every project at once. So teams paste the same company document into project after project, and each copy starts aging the moment it lands.
When Claude Projects are enough
If you work solo, live entirely in Claude, and your work splits cleanly into a handful of projects, project knowledge alone will serve you well. Paste your background into each one and move on. The maintenance cost of a few copies is real but small.
Where the two differ
| Claude Projects | Company Brain | |
|---|---|---|
| Scope | One project inside Claude | Every chat, every project, every tool |
| Works in | Claude only | Claude, ChatGPT, Copilot, Cursor, any MCP client |
| Company facts | Copied into each project by hand | Maintained once, delivered everywhere |
| When facts change | Update every project that holds a copy | Update one place, every tool follows |
| Quality control | Whatever was pasted into the project | Human review before facts go live |
| Best at | Deep context for one piece of work | Standing company knowledge |
The maintenance test
Count the places where your company describes itself to an AI right now. Project instructions, pasted documents, someone's saved prompt. Each copy is correct exactly until the company changes, and companies change constantly. We traced how teams escalate from pasting context to something maintained on the blog, and copied project knowledge is a recognizable rung on that ladder.
Company Brain gives that knowledge one reviewed home and delivers it to Claude through one MCP connection, alongside whatever project knowledge the work at hand needs. Projects stay great at what they do. The company's truth stops living in copies.
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 per company, never per seat.
Frequently asked questions
- Do Claude Projects and Company Brain compete?
- Claude Projects and Company Brain don't compete. Keep project knowledge for project material and let Company Brain carry the company facts underneath. Together, a chat in any project starts with both the project's context and the company's.
- We pasted our company profile into every project. Isn't that the same?
- A pasted company profile stays correct until the profile changes. Then someone updates six projects, misses two, and the team spends a month getting answers based on the old positioning. Company Brain updates once and reaches every project and every tool.
- What about teammates who use ChatGPT or Copilot?
- Claude project knowledge stays inside Claude. Company Brain delivers the same approved facts to Claude, ChatGPT, Copilot and Cursor through MCP, so teammates in other tools work from the same company context.
- What does Company Brain cost?
- Company Brain's core product is free forever: 50 company facts, one curator, whole team connected. Pro is €89 per month and Team is €199 per month, both per company, never per seat.
