Talk, share, and make decisions in open channels across your team, in private groups for sensitive matters, or use direct messages one-to-one.
Drag and drop files, documents, PDFs, images, and videos to share with anyone and get immediate feedback and discussion through comments.
Search across your entire team archives, within documents, files, or images, and filter your results by recency, relevancy, person, and more.
Everything you do on our desktop app is reflected on our fully native iOS and Android apps, and vice versa. Everything is in sync—pick up right where you left off.
It’s not ‘yet another app’ you have to use. Slack works with all the tools you already use; set them up to post notifications directly to Slack in a single work space.
All data transfer is encrypted (256-bit AES and TLS 1.2) on the desktop or the phone. We perform security testing regularly to identify and resolve any vulnerabilities.
We spend 47% of our time just reading, answering, and searching email to gather what we need to do real work. Slack helps you work in the moment — making it faster and easier to communicate with your team, with all the collective knowledge at your fingertips. More productivity, more transparency, and less email. That’s Slack.
Slack integrates with over 80 external services to help you pull information from outside tools in a way that’s timely, relevant, and always searchable. No more switching between apps. Bring it all together in one simple place.See all integrations
Stay in sync with native apps for iOS and Android. Send messages, share files, get notifications, search your team archives, and more — we built our apps to give you a full-featured experience on any device you prefer.See all apps
