What is slack?

I’m not sure exactly what you mean. Is it an object, a behavior, a word?
assistant
I thought it was a program or something?
user
Do you mean “Slack”, or the “Slack App”?  They’re different.
assistant
Yes the slack app

OK.  The “Slack App” is a collaborative software tool, which lets you work together with others to coordinate communication and synchronize a variety of documents, files, ideas, etc.  It’s quite popular these days, which is why you’ve heard about it.  Maybe you think of it as similar to “sharing your computer with others”, or “having a back-channel for collaboration”, or something like that?

It’s an app for communicating with people at work, or a small work group.  It’s free and you can use it on multiple platforms.
