Slack is…
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.
Private Channels
For sensitive information, create private channels and invite a few team members. No one else can see or join your private channels.
Direct Messages
To reach a colleague directly, send them a Direct Message. It’s completely private and secure.
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.
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.
Search your entire 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.
To the Moon!
