If you use Google’s Messages app or Gmail, then you’re familiar with Smart Reply. Thanks to machine learning, the feature anticipates what you’re going to type before you type it out. With the upcoming Android Q release, Smart Reply will be heading to other third-party messaging apps. Aside from using it to reply to messages, it’ll also anticipate your actions. So, if a friend sends you an address, it’ll assume you want to open Google Maps and suggest that to you. If you’re worried about sending your activity to Google, the machine learning happens on-device, so you don’t have to worry about it hitting Google’s servers. The company has really been rallying around promoting the privacy and security of its users with this next Android release.
