Keep the conversation next to the work
A channel for every project, plus group chats and direct messages. Decisions stay beside the tasks they're about, not lost in another app.

Three kinds of conversation, one inbox of unread
Project channels
Every project gets its own room. Only people on the project can open it.
Group chats
For the people who need to talk, whatever project they're on.
Direct messages
One-to-one conversations with anyone in your workspace.
Side topics get their own room
Reply in a thread and the main channel stays readable. The message shows how many replies it has; one tap opens the whole discussion.
- Threads one level deep, so they never sprawl
- Reply from the web app or the mobile app


Reach the right person, quietly
Write @ and a name, and that person is notified. Everyone else in a busy channel gets one summary notification instead of one per message.
Find that message from last week
One search box covers tasks, messages and comments. Results only include what you're allowed to see.

Everything you expect from team chat
Reactions
Answer with an emoji instead of another message. See who reacted.
Edit and delete
Fix a typo and it shows as edited. Delete a message and it's gone for everyone.
File attachments
Share files up to 10 MB, stored privately and opened only after a sign-in check.
Typing indicators
See when someone is writing a reply in the web app.
Clear a conversation
Hide a conversation from your own list, or clear its history for everyone in it. Anyone who can post in the conversation can clear it.
Never miss a message
Messages arrive live. If your connection drops, everything you missed catches up.
