Your Brain, in Claude

Claude reads the folders, notes and documents in your Brain — PDF, Word, PowerPoint, Excel and more — and works from them, filing everything it makes.

Why MCP

Why do this from Claude

Your documents as context

Brand books, briefs, decks and spreadsheets in the Brain are read page by page, so Claude works from your facts, not guesses.

Folder notes that remember

Every folder carries a note Claude reads before it works there — and appends to when it learns something worth keeping.

Filed by asking

Claude creates folders, moves files and saves pictures from a link straight into the Brain, on the server.

  • “What do I have in /Campaigns? Tidy last month's files into their own folder.”

  • “Save this picture into /Inspiration and note why we liked it: https://…”
