Slack Huddles vs Teams Meet Now: Start a Quick Call
Some questions are faster to answer out loud. Slack calls the quick version a huddle, and Teams calls it Meet now. Both start from the conversation you are already in, but they work differently once you are in the call. Here is how each one starts, who can join, and what to watch for, according to their help pages.

The quick version
In Slack, click the headphones icon in any channel or DM to start a huddle. Anyone in the conversation can join. On the free plan a huddle holds two people; paid plans allow up to 50 participants, with 25 on video at once. In Teams, use Meet now in a chat, group chat or channel, or type /meetnow in a chat. A Teams instant meeting keeps its chat, recording and shared files after it ends.
Slack: start and join a huddle
Open a channel or DM and click the headphones icon at the top of the conversation, then click the camera icon if you want video. On mobile, tap the headphones icon in the conversation header. Huddles run in the Slack desktop and mobile apps, plus Chrome and Firefox. Frontline Members cannot start huddles but can join them. When a huddle is running in a channel you belong to, a headphones icon appears next to the channel name in your sidebar; click it, or click Join if the huddle started in a DM or you were invited. If you follow a huddle link into a private channel or DM you are not part of, click Request Access and anyone in the huddle can let you in.
Slack: invite, share the link, take notes
Inside a huddle you can invite people who are not in the channel or DM. Slack notes that they will not be able to see the conversation's messages or the huddle thread. Every huddle also has a link: click the arrow next to the headphones icon and choose Copy huddle link, and the huddle starts when someone clicks it, which works well in a calendar invite. Each huddle has a dedicated thread for notes, links and files, and a canvas for meeting notes that stays available as a tab after the huddle ends. Up to two people can share their screen at once, and live captions are available in English only and are not saved. A huddle ends automatically when the last person leaves.
Teams: Meet now in a channel, group chat or chat
In a channel, choose Meet now in the top-right corner, then Join now. To keep the call attached to one conversation, use Reply under a post, then Actions and apps, then Meet now. In a group chat, select Meet now at the top of the chat; others see that a meeting started and can open the chat and select Join. Instant meetings in group chats do not ring anyone by default: select the live indicator, then Ring others to join to ring individuals or Ring all. In any chat you can also type /meetnow in the compose box and press Enter or Tab. If you start from the Calendar tab with Meet now, you can name the meeting, get a link and change meeting options, but that route needs an Exchange Online mailbox.
Teams: invite people and rejoin
After you join, Teams prompts you to invite others. Copy the meeting link, search for names under People and Participants, or use Share invite to send an email. If you are not the last person to leave a group chat meeting, you can rejoin from the chat with Join; when the last person leaves, everyone is notified that it ended. Everyone who attends keeps access to the meeting chat, the recording and anything shared in it, even after it ends.
Which one for what?
Our read: a Slack huddle is the lighter option, a drop-in audio room attached to a channel with a notes thread built in, so use it for a five-minute unblock. Teams Meet now behaves like a real meeting that happens to start fast, so it suits calls where you want a recording, a link for outsiders or a lasting meeting chat. If a call is not needed at all, a short recorded clip lets people reply when they have time.
What to be careful about
- Free Slack huddles hold two people. Bigger groups need a paid plan, which allows up to 50 participants and 25 on video.
- Anyone in the channel can join a Slack huddle. Starting one in a big channel invites everyone in it.
- Slack invitees only see the huddle. People you invite from outside the channel cannot read its messages.
- Teams group chat meetings start quietly. Use Ring others if you need people to notice.
- Calendar Meet now needs a mailbox. Without Exchange Online, start from a chat or channel instead.
- Slack live captions are English only. They are not saved when the huddle ends.
