About this guide

Channels keeps work visible and searchable. Use public or private rooms, keep side conversations contained in threads, and attach files through File-Vault with previews and expiring links. Pin a living Canvas to each channel for runbooks or briefs.

With one click, convert an important thread into an Agent Desk ticket, route tasks into ActionDesk, and log every key moment to Chronicle. Moderation, DLP, retention and legal hold are workspace-level guardrails. Optional AI summaries help teams catch up quickly.
