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.



Of course, every company and every person is different, so we want to get more input on how Inbox will work at your company. Starting next month, we’ll begin enabling Inbox for a small group of Google Apps customers to learn about their needs, challenges and use cases.
  • Do you want to use Inbox as your primary email at work?
  • Are employees at your company heavy mobile users?
  • Most importantly, do you want to partner with Google on user studies to help build the new work Inbox?
If you answered “yes, yes and yes!” then email [email protected] from your Google Apps for Work administrator account to apply for an invitation to the early adopter program. To start, we plan to work very closely with the early adopter companies, so not everyone that applies will be accepted right away, but the program will continue to expand over the coming months.

Inbox wasn’t created to reinvent email, Inbox was created to help you reinvent the way you get things done. This means we need to understand more about how things get done (or don’t) today. And with your feedback, who knows, we could reinvent the way people work.

Note: Only the Google Apps administrator can apply for entry to the Inbox for work early adopter program.
