Welcome to KetBook - Privacy-First Knowledge Management
Welcome to KetBook
We're excited to introduce KetBook, a privacy-first knowledge management application for macOS. Built with one core principle: your data belongs to you and you alone.
Why Privacy Matters
In an era where data breaches and privacy violations are commonplace, KetBook takes a different approach. We believe that your personal notes, thoughts, and knowledge should never live on someone else's server.
Our Privacy Architecture
KetBook implements a zero-trust architecture:
- Apple Sign In - Secure authentication through your Apple ID
- CloudKit Private Database - Your profile stored in your private CloudKit space
- iCloud Drive Storage - Documents live in your personal iCloud Drive
- User-Provided AI Keys - AI features use your own Ollama Cloud API key
- Complete Isolation - No user can access another user's data, ever
Key Features

- Schema Generation - 100% automatic JSON schema generation from Swift code
macOS Integration
