If you've wanted to use Google's canned Smart Replies in chat apps, you've been limited to using Allo or (if you're on the right carrier) Android Messages. But what if you're one of the many, many people using something else? Don't fret: Google's experimental Area 120 group is working on a Reply project that, as the name implies, will bring Smart Replies to many messaging clients (currently just for Android). Hangouts is logically on the list, but so are third-party apps like Facebook Messenger, Skype, WhatsApp and even Twitter's direct messages. You'd only have to tap a button in your notifications to confirm that you're on your way or say you're doing well.
