Organize your team conversations in open channels. Make a channel for a project, a topic, a team, or anything—everyone has a transparent view of all that’s going on.
For sensitive information, create private channels and invite a few team members. No one else can see or join your private channels.
To reach a colleague directly, send them a Direct Message. It's completely private and secure.
Connect all the tools you use to Slack and avoid all that constant switching between apps. Set up your integration so that you get all your notifications directly within Slack—from support requests, code check-ins, and error logs to sales leads—all of them searchable in one central archive.
Everything in Slack—messages, notifications, files, and all—is automatically indexed and archived so that you can have it at your fingertips whenever you want. Slack also indexes the content of every file so you can search within PDFs, Word documents, Google docs, and more. With one search box and a set of powerful search operators, you can slice and dice your way to that one message in your communication haystack.
With fully native apps for iOS and Android, whatever you do on one device is reflected everywhere. Everything is in sync. We’ll keep your place so you can always pick up wherever you left off.See all apps
