Team communication
for the 21st century.

Channels

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

Direct Messages

Send messages directly to another person or to a small group of people for more focused conversations.

Calls

Take a conversation from typing to face-to-face by starting a Slack voice or video call in any Channel or Direct Message. From there, you're one click away from sharing your screen, so everyone can follow along.

Drag, drop, and share your files.

Not just your messages, but all your files, images, PDFs, documents, and spreadsheets can be dropped right into Slack and shared with anyone you want. Add comments, star for later reference, and it’s all completely searchable.

If you use any services like Google Drive, Dropbox, or Box, just paste the link and that document is immediately in sync and searchable too.

Slack integrates with companies like Asana, Twitter, Google Drive, Github and more.

All your tools in one place.

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.

Everywhere you go.

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.
