Slack

A messaging app for team collaboration from Slack Technologies (www.slack.com). Introduced in 2013 and originally developed as a tool for its own video game development, Slack lets people organize chat "channels" for projects, departments, groups of users, etc., all of which reside in a sidebar. Messages can also be made private, and files can be shared by dropping them into a channel.

Documents can be searched, and social media, cloud storage and other services can be plugged in to keep all communications in one place. Available as a freemium product, the paid versions offer many more features, including tech support, usage statistics and unlimited searching and service integration. See collaborative software.
