Cozy answers questions about years of your iMessage — on your Mac, where the messages already live. No upload. No cloud index. Only your question and the few excerpts that answer it ever leave.
Version · Requires macOS 26 Tahoe
Your question and the excerpts that answer it are sent for AI processing — Cozy stores none of it. Everything else never leaves your Mac.
Your messages stay on your Mac and are never uploaded. When you ask a question, Cozy sends only your query and the relevant excerpts it finds to our servers for AI processing. The answer comes back to your Mac, and Cozy stores none of it.
Yes. Cozy reads your full local Messages history — iMessage and SMS, including group chats — and resolves names from Contacts, so you can ask "what did Sarah say?" instead of searching a phone number.
No. Cozy is read-only: it reads your local history and answers your questions. It never sends, posts, or changes anything. Quiet by design.
Cozy requires macOS 26 (Tahoe) or later, on both Apple Silicon and Intel Macs.
