Google adds Smart Reply to Gmail on iOS and Android

Google's Smart Reply feature, which suggests quick responses to your messages, that is already available on Inbox by Gmail and Google Allo is coming to Gmail.

The Smart Reply feature will suggest three short responses based on the email you received and then allows you select a response, and send it immediately with the smart reply text. You will also be able to edit the response before sending. 

The main aim is to save time while replying to received messages, when you're on the go. The feature uses machine learning to offer you the best response as you start using it more often. So if you’re more of a “thanks!” than a “thanks.” person, Smart Reply will suggest the more suited response.

Smart Reply will roll out globally on Android and iOS in English first, and Spanish in the coming weeks, with other languages to follow.
