Computer, respond to this email: Introducing Smart Reply in Inbox by Gmail

Posted by Bálint Miklós, Software Engineer

With the holidays approaching and emails coming in at a furious pace, we can all use a little help. Inbox is already on hand assisting you with the next step, organizing your trips, and even suggesting reminders.

But when you're checking email on the go, it can be cumbersome and time-consuming to reply to all or even some of them. What if there was a way for your inbox to guess which emails can be answered with a short reply, prepare a few responses on your behalf and present them to you, one tap away?

Well, starting later this week, Inbox will do just that with Smart Reply.

Smart Reply suggests up to three responses based on the emails you get. For those emails that only need a quick response, it can take care of the thinking and save precious time spent typing. And for those emails that require a bit more thought, it gives you a jump start so you can respond right away.

There's actually a lot going on behind the scenes to make Smart Reply work. Inbox uses machine learning to recognize emails that need responses and to generate the natural language responses on the fly. If you're interested in how Smart Reply works, including how researchers got machine learning to work on a data set that they never saw, you can read more about it on the Google Research Blog.

And much like how Inbox gets better when you report spam, the responses you choose (or don't choose!) help improve future suggestions. For example, when Smart Reply was tested at Google, a common suggestion in the workplace was "I love you." Thanks to Googler feedback, Smart Reply is now SFW :)

Smart Reply will be rolling out later this week on both Google Play and the App Store in English. If you've got a lot of emails on your plate, now's a great time to try Inbox and get through them faster than ever.
