Google’s Inbox app, a streamlined version of Gmail, already comes with plenty of features meant to expedite the emailing process, filtering out low-priority items and giving you the option to hit “snooze” on a message you want to deal with later.
Smart Reply is a new feature that aims to take Inbox to the next level. Using deep learning algorithms, Smart Reply reads your emails and then automatically generates texts you can pick as your replies.
Smart Reply was built on the foundations of two existing programs—spam detection and email categorization—which were woven together to create an algorithm that could synthesize conversations.
