The Google Assistant is one of the main interfaces for Google Search, Google's flagship product. Google is accustomed to serving billions of searches per day, but when Google made the Assistant exclusive to the Pixel phones, it limited the usage of the heavily-promoted interface to a tiny fraction of possible users. Today, Google is finally lifting the arbitrary limits on the Google Assistant and bringing it to all Android phones running version 6.0 and up—about 30 percent of active devices.
