Google will soon cast an even wider net with its AI age estimation technology. After announcing plans to find and restrict underage users on YouTube, the company now says it will start detecting whether Google users based in the US are under 18.

Age estimation is rolling out over the next few weeks and will only impact a “small set” of users to start, though Google plans on expanding it more widely. The company says it will use the information a user has searched for or the types of YouTube videos they watch to determine their age. Google first announced this initiative in February.

If Google believes that a user is under 18, it will apply the same restrictions it places on users who proactively identify as underage. In addition to enabling bedtime reminders on YouTube and limiting content recommendations, Google will also turn off Timeline in Maps, disable personalized advertising, and block users from accessing apps for adults on the Play Store.
