Gmail’s Inbox app can now respond to emails for you, automatically. This new feature is called “Smart Reply” and it is suppose to automatically suggest short responses to messages where a lengthy reply may not be necessary. Smart Reply will suggest up to three responses based on the incoming email, and allow you to quickly respond with a single tap. Smart reply will do all the thinking for you and guess which emails can be answered with a short reply, and if short response is not possible because the email needs to be more personal, it gives you a jump start so you can respond right away.

Smart Reply will learn how you reply over time in order to offer better suggestions and it is due to hit both the Android and iOS versions this week, and you will be able to try for yourself.
