Gregg is coding agent you text locally and improve over time. It runs on a Mac mini with its own Apple ID, so you talk to it in iMessage like a friend. It replies in threads, tapbacks, sends files, and puts anything long (reports, plans, videos) on a desk card that opens on your phone. It is able to manage different projects and sessions through different reply threads, signfiying different sessions through emojis and linking itself with various tools (AWS, Modal, etc.) as necessary.

There's also a bridge with one link you send a teammate that connects their coding agents or local browser agents to your Gregg. You start a text with 💻 and agents answers in your thread, and files go both ways. In the demo, Gregg builds the link for Sydney, and when Nathan texts "send it", Gregg texts it to her itself.
