Channels & Messaging

Open Discussions from the sidebar to see the workspace's channels. Channels are persistent, workspace-wide chats — the place for team conversation that isn't tied to a single task.

Working with channels

• The list on the left has four sections: Public channels, Direct Messages, and the shared channels, Shared by us and Shared with us. Each row shows a preview of the last message and what is unread. Select one to open it.
• Create a channel — click + at the top of the list. In the New discussion dialog choose the type: Public, open to the whole workspace; Direct, private to the people you pick; or Between workspaces, a channel shared with a trusted partner workspace (see Shared Channels).
• Rename and archive — from a channel's menu in the list. A channel can be renamed or archived by the person who created it or by a workspace admin. An archived channel takes no new messages and leaves the list; what was written stays readable from a direct link. The default channel can't be archived.

Messaging

• Write messages in Markdown using the composer at the bottom of the thread.
• Mention people and agents with @. Mentioning a person notifies them; mentioning an agent triggers a run, and the agent replies in the thread.
• Reply to a specific message to keep a sub-conversation clear.
• React to messages, and edit or delete your own.
• New messages appear in real time for everyone in the channel.

Talking to an agent in a channel

Type @ and pick an agent, then ask your question. The agent receives the recent thread context, may call tools, and posts its answer as a normal message. This is the same mention mechanism used on tasks and in brainstorms — see AI Agents for how a run works and Workspace Settings for configuring which agents exist.

Direct Messages

Alongside channels, you can have private one-on-one and group conversations. Start one with + at the top of the list: choose Direct in the New discussion dialog and pick one person for a 1-on-1 or several for a group.

• Private to the people you choose — a direct message is visible only to its members; no one else in the workspace can see it, read it, or find it.
• A Direct Messages section in the sidebar lists your conversations newest-first, each showing who's in it, a message preview, and an unread count that clears when you open it.
• Name a group — conversations of three or more people can be given a name; one-on-ones are labelled by the other person.
• Adding someone starts a new conversation with the larger group and leaves the original untouched — its history stays private to its original members. Reopening a chat with the exact same people takes you back to it.
• Hide without leaving — hide a conversation to tidy your sidebar; a new message brings it back.
• Notifications — every direct message is meant for you, so you're emailed about it in the daily digest, but DMs stay out of the Inbox (which is for @mentions, replies, and assignments); their unread lives in the sidebar instead.
• Mentions & agents — inside a DM the @-mention list is limited to its members, and agents can still be mentioned and reply, visible only to the people in the conversation.
