What is Slack?

Slack is a messaging app for business that connects people to the information they need. By bringing people together to work as one unified team, Slack transforms the way organizations communicate.


Working in Slack

Slack helps you work in a more connected, flexible, and inclusive way.


Slack makes access to your coworkers easy — message anyone inside or outside your organization and collaborate just like you would in person. People can work in dedicated spaces called channels that bring together the right people and information.


Slack supports asynchronous work. When work is organized in channels, no matter your location, time zone, or function, you can access the information you need on your own time. Ask questions, get caught up, and share updates without having to coordinate schedules. 


In Slack, everyone in an organization has access to the same shared and searchable information. When teams work together in channels, information can be shared with everyone at once, helping keep teams stay aligned and make decisions more quickly.
