Google rolling out Smart Replies to Gmail’s Inbox app later this week

The Gmail team’s Inbox mobile email client, which was born out of Google’s 2012 acquisition of the popular iPhone email app Sparrow, is about to get a whole lot smarter with a new feature called Smart Reply, the company announced on the Gmail blog Tuesday.

The feature analyzes your emails and uses machine learning to recognize emails that need responses and then generates the natural language responses on the fly.

How Smart Replies work

With Smart Replies, the app suggests up to three responses based on the emails you get. This is similar to how Messages in iOS 9 analyzes your message exchange to intelligently provide canned responses based on the contents of the message.

Based on the responses you choose—or don’t choose, for that matter—the app will improve future suggestions. Smart Replies won’t magically automate the process of responding to each and every email you receive, but can be a nice time-saver for those messages that only need a quick response.

“And for those emails that require a bit more thought, it gives you a jump start so you can respond right away,” says Google.

The feature will be rolling out later this week to Inbox for English users.

The app is localized in English, Arabic, Bokmål, Norwegian, Bulgarian, Catalan, Chinese, Croatian, Czech, Danish, Dutch, Finnish, French, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Malay, Polish, Portuguese, Romanian, Russian, Slovak, Spanish, Swedish, Thai, Turkish, Ukrainian and Vietnamese.
