Slack is a powerful messaging app that allows you and your teammates to quickly message back and forth without the hassle of email. But it's not just AOL instant messenger 2.0. Slack has powerful features and integrations that make it possible for you to integrate all of your other daily tools -- like Trello, Gmail, Giphy, and so many more -- right where you're already communicating. You can start channels between different teams or just chat with specific colleagues. Slack makes remote and in-person work possible and easier than ever.
