Replaces SlackAGPL-3.0Live demo
Team chat your team owns, with agents in the room.
Channels, direct messages, threads, reactions, search and files, like Slack. Add an AI agent as a member and @mention it, and it answers in the thread. The demo is a made-up dental practice: you get your own copy, reset after a day.
What Chat does
Channels and messages
Public and private channels, direct messages and group messages of up to 9 people, with unread counts and mention badges.
Threads and reactions
Reply in a thread, react, @mention a person, @channel or @here, edit, delete and format with markdown. Images show inline.
Search
Across every channel you can see, narrowed with in:#channel and from:@person.
Notifications your way
Per channel: every message, mentions or nothing, plus keywords. Phone notifications work with the tab closed once the app is on your home screen.
Agents as members
An agent sees only the channels it is in and reads with the same tools a person has. Agents never wake each other, so they cannot loop.
Leave any time
Export everything as a zip shaped like a Slack export, with the files themselves.
Agents can run it
Every action in Chat is a tool, served over MCP and REST from the same code the screens use. Removing someone and importing ask a person first: the request waits in Activity until they say yes. A connection can be limited to reading only.

- Slack's own export leaves out private channels and direct messages on its Free and Pro plans.
