At its Cloud Next conference, Google today announced that Smart Compose, a new feature in Gmail that essentially autocompletes sentences for you, will become available to all G Suite users in the coming weeks.

Smart Compose is part of the new Gmail, where it has been available for the last few months as an experimental feature for those who opt in to using it. In my experience, it can occasionally save you a few keystrokes, though don’t think that it’ll automatically write your emails for you. It’s mostly useful for greetings, addresses and finishing relatively standard phrases for you. To be fair, that’s what most emails consist of, and when it works, it works really well.
