Summary
According to Google, Chat is simply a way for two or more people to chat together without any formalities — for example, if you wanted to quickly talk about where you were going to meet for lunch, you’d create a group conversation among your friends. Your Gmail screen will refresh, and you will probably get a pop-up welcoming you to the “new Gmail.” Instead of the Meet and Hangouts boxes that used to be on the left-hand side of your Gmail screen, you’ll now have a Chat box, a Rooms box, and a Meet box.
