If you are familiar with things like Slack or Discord it is something like that. It is based on Mattermost which is a very nice open source platform for chats via computers or phones. You can join 'rooms' which revolve around certain topics or interests.
You can also talk privately with people, though I am not wholly sure if it is encrypted chat or not. Methinks probably not. Still there are other solutions for that which you can ask me about if you are interested.
