20 Questions With Google's Assistant and Apple's Siri

MOUNTAIN VIEW, Calif.--If you own an iPhone, there's yet another way to talk with an artificial intelligence trained on the whole internet and beamed down to your handset from a cluster of computers somewhere in the world. Tuesday, Google made its artificial-intelligence powered Assistant available for the iPhone. The service, which uses a conversational interface to do things and provide information for users, has been available on Android phones since spring of last year. The move brings the company's voice interface into direct competition with Apple's own Siri. For the first time, you can now have both assistants on the same phone in your palm.
