Reyn — Always-On AI That Watches Your Screen, Stays on Your Mac

Reyn is a privacy-first desktop AI for Mac. It watches your screen, builds a private journal of your work, and answers questions about your week. Your screen is captured and stored on your device — AI runs in the cloud, but never sees your raw screen.

What Reyn does

Journal & recall — Ask "what did I work on yesterday?" or "what did we agree on in Tuesday's call?" and get a grounded answer from your own screen history.
Live context — Reyn knows what's on your screen right now, not just what was there last week.
Workflows you can share — Carry out a process once and Reyn captures the steps so you can hand them off to a teammate.
Morning brief — A short daily email recap of what you wrapped, what's still open, and what deserves attention today.
On-device capture — Your raw screen data never leaves your Mac. AI runs in the cloud on your journal text only.
Multi-provider AI — Works with the AI models you already use.
