Personal Knowledge Brain
A native macOS app and MCP server that gives AI assistants a memory: it captures and indexes work activity and documents, and lets Claude read and act on Mail, Calendar, Reminders, Contacts, Notes and Messages, with mail always drafted first and sent only when asked.

Personal Knowledge Brain
The idea
An AI assistant is only as useful as what it knows about your work.
What I built
- Capture and recall: activity, documents and notes indexed for search and timeline recall.
- Personal data tools: Mail, Calendar, Reminders, Contacts, Notes and Messages exposed to Claude through one MCP server.
- Safety by design: email is drafted first and sent only on request.
- Native: a Swift macOS app.
Private system: a walkthrough or live demo is available on request.
