Apple protects the Messages database with Full Disk Access permissions. Cozy needs this to read your message history. Calendar access is requested separately.
Cozy requires macOS 26 (Tahoe) or later, and works on both Apple Silicon and Intel Macs.
CozyBot can search and read PDFs, text files, and documents on your Mac. It uses Spotlight to find relevant files and extracts their content to help answer your questions.
