Slack is an online messaging app with fancier features. Stewart Butterfield helped create it. It was originally for a video game. But then they just made it a simple messaging app and dropped the video game idea. "Slack" stands for "Searchable Log of All Conversation and Knowledge."

Slack has a workspace - it's a shared place where a team uses Slack. People can join a workspace if they get an invitation or a special link. Slack uses channels, which are like chat rooms. A channel can be public (anyone in the group can join) or private (only invited people can join). People can also send direct messages to one person or to a small group. A group chat can later become a private channel.

Slack can connect to many other apps, like Google Drive, Trello, Dropbox, and GitHub. It can also connect to calendars and other services.

Slack provides mobile apps for iOS and Android in addition to their web browser client and desktop clients for MacOS, Windows, and Linux (beta).

Slack is a freemium product. This means people can use it for free, but some extra features cost money.

All content, including files, conversations, and people, is searchable within Slack. Users can express their reactions in the form of emojis to any message.
