Smart Compose in Gmail now available for G Suite
What’s new: We’ve already made it easier to reply to emails; we’re now making it easier to compose them. Smart Compose in Gmail, now available to G Suite users, intelligently autocompletes your emails. At launch, it can fill in common phrases and relevant addresses, like that of your home and office; in the future, it will get smarter—learning your most-used greetings.
Smart Compose is on by default for all G Suite users. They can turn it off in their Gmail general settings (Smart Compose > Writing suggestions off).
