The collaboration software that moves work forward
See how work gets done in Slack
Slack brings all your communication together
Teamwork in Slack happens in channels — a single place for messaging, tools and files — helping everyone save time and collaborate together.
Collaboration beyond colleagues
Share channels with companies and businesses you regularly work with – like clients, vendors, and partners – to bring all the right people into the same room.
Talk it out over voice or video calls directly from Slack. And if you need to show your work, you can share your screen, too.
Drag-and-drop PDFs, images, videos and other files directly into Slack. Get feedback on your work and create an archive of your progress.
Streamline your work with integrated tools
In Slack, tools and services work in the same place as your team. Information leaves siloed inboxes and flows into shared team channels.
Connect your tools with Slack
The Slack App Directory has over 2,000 apps you can integrate into Slack. Spend less time juggling tabs and more time focusing on meaningful work.
Or build your own with our APIs
