Matrix is an open decentralised chat/messaging/VoIP/data-sync protocol; you can use it with an app like Riot.im for Slack-style UX, but with bridges through to IRC, Slack, Gitter, Telegram, XMPP etc.

So, in short, Matrix is to Slack as OStatus is to Twitter. (And Riot is to Matrix as Mastodon is to OStatus).
