Microsoft designed their Microsoft Teams chats app for meetings and documents.
It works well for random conversations but is at its best when you're hammering out a proposal or outlining a project together with a team. Invite everyone who should be in that team, and they'll automatically be able to join in every channel in that team.
Slack's the 900 pound gorilla in the room, the team chat app you've most likely heard of and tried already.
Launched in mid-2013 by the team that built Flickr, it quickly became one of the most popular ways to chat in groups.
Then, whenever you have a meeting, Microsoft Teams makes a new chat room just for that meeting.
You can jump on a video call, share your screen, and log every discussion in long-form messages. One of the newest ways to chat with your team is Google Hangouts Chat, a team chat companion to their popular Hangouts video chat.
Or, you can write a full wiki of documents as a permanent record of what your team does, and share Office Online documents in your chat.
Then, there are private messages, where you can directly message a colleague or chat with a smaller group away from group discussions.
Tying it all together is universal search to find old conversations and files quickly.
Twist, a team chat app from the Todoist team, changes that by turning all team chats into threads.
It includes standard channels for group conversations—but when you want to say something, you either have to comment on an existing thread or start a new one.
