Google is constantly teaching the Google Assistant new tricks, and this week, the assistant is learning how to navigate websites and book movie tickets. Soon, after asking your phone-based Google Assistant for movie showtimes, a new "Buy tickets" button will pop up, and tapping it will whisk you through the ticket-buying process—no extra apps required.

Google says the feature works with "more than 70 cinemas and ticketing services, such as Fandango, MovieTickets.com, AMC, or MJR Theaters in the US, or ODEON in the UK." While all of those services could have coded up special hooks for the Google Assistant, that's not what's going on here—instead this feature is powered by a feature Google calls "Duplex on the web." You might remember "Duplex" as Google's futuristic phone-call bot that can book restaurants over the phone while sounding like a real human. This "Duplex on the web" doesn't make phone calls, though, and instead navigates websites for you and completes the movie ticket purchase. Google announced this feature earlier in the year during the Google I/O keynote, where CEO Sundar Pichai defined Duplex as "the approach by which we train AI on simple but familiar tasks to accomplish them and save you time."
