Slack

Slack is a workplace platform where teams talk, share files and use connected applications and AI assistants. Companies from large enterprises to small local businesses use it to bring the right people and information together.

Its current site presents it as an AI work platform. The assistant, Slackbot, can summarise conversations, search across company history and coordinate work between apps. The company is headquartered in San Francisco and has offices in several countries.
