Pick a channel or a person, type your message, and send it — your workspace's default channels are ready as soon as you join.
Steps
- From Home, open the Team or Messages tab.
- Pick where to post:
- Tap the message box at the bottom, type your message, and attach a file or image if you need to.
- On iPhone, iPad, and Mac the composer toolbar includes Bold, Italic, lists, Block quote, and code. On the web, chat formatting is bold, italic, strike, code, and lists — not block quote or tables.
- Send it. If you're replying to a specific message instead of starting a new topic, use Reply instead so the main channel stays readable.
If you don't see any channels yet
New workspaces start with a few default channels. If your team hasn't created any yet, use New Channel to create one for your team, project, or topic — see How do I create a channel?.
Tips
- You can message an installed app or an AI agent the same way you message a person — see How do I message an app or agent in a channel?.
- Sent a typo? You can edit or delete afterward, or forward the message to someone else.
- On iPhone, iPad, and Mac you can say “Send a message in FabricLoop” to Siri — see Siri and Shortcuts.
