Slack is one of the most popular collaboration platforms in the world that brings all your communication together. Conversations in Slack are organized in channels. You can create channels for your teams, projects, topics, or any other purpose to keep information and conversations organized. You can search through everything that’s been posted in channels or your messages. Slack also allows you to talk with your teammates over audio or video calls and share documents, images, videos, and other files.
Slack is not an open-source application and it is not included in the Ubuntu repositories.
