Team chat is direct messages and group chats for your staff. The difference is what happens when somebody pastes a ticket, a contact, a lead or an order into a conversation.
Everything on this page is shipped and running today, and free on every account.
Paste a ticket, contact, lead, review, campaign or order and it renders as a card with its title, status and owner, one click from the record itself. Not a bare URL somebody has to go and look up.
A DM is between the two people in it. The owner of the workspace cannot read it, and message bodies never reach the activity log.
Groups with a General everybody joins, mentions that notify, files and images, typing indicators, read receipts, presence, and working hours you set yourself.
Four questions and you get a workspace you can open, with the apps your business runs on already switched on. No signup, no card.
