Cozy answers questions about years of your iMessage — on your Mac, where the messages already live. No upload. No cloud index.
Open cozybot.ai on your Mac to download.
Ask what Sarah said about the lake house, when Dad's flight leaves, what the landlord promised, who needs a reply, or what the group chat decided while you were offline.
Your question and the excerpts that answer it are sent for AI processing — Cozy stores none of it. Everything else never leaves your Mac.
Cozy finds conversations waiting on you and drafts a response that sounds like you. You review it in Messages and decide whether to send it.
Find what's waiting
Awaiting Reply surfaces incoming messages that still need your attention.

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.
Cozy can draft a reply in your voice and open it in Messages, but it never sends anything. You review the draft and press Send.
Cozy requires macOS 26 (Tahoe) or later, on both Apple Silicon and Intel Macs.
