What is Slack? A messaging app for teams.
All your communication in one place, integrating with the tools and services you use every day.
Some of the great uses for Slack
Slack for Group conversations
Talk, share, and make decisions in open channels across your team, in private groups for sensitive matters, or use direct messages one-to-one.
Slack for File sharing
Drag and drop files, documents, PDFs, images, and videos to share with anyone and get immediate feedback and discussion through comments.
Slack for Deep, contextual search
Search across your entire team archives, within documents, files, or images, and filter your results by recency, relevancy, person, and more.
Always in sync
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.
Slack uses Over 80 integrations
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.
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.
To reach a colleague directly, send them a Direct Message. It’s completely private and secure.
Slack Private Groups
For sensitive information, create Private Groups and invite a few team members. No one else can see or join your Private Groups.
With fully native apps for iOS and Android, whatever you do on one device is reflected everywhere. Everything is in sync. Slack will keep your place so you can always pick up wherever you left off.
