Credit: Edgar Cervantes / Android AuthorityGoogle is expanding its AI-powered age checks beyond YouTube to more of its US services.The system uses machine learning to estimate if you’re under 18 based on your activity.If flagged as a teen, you’ll face restrictions unless you verify your age with an ID or selfie.It turns out the new Google AI age checks aren’t just a YouTube thing. The company is beginning to roll out a broader age assurance system across its entire platform in the US, which means more of your online activity could soon be used to judge whether you’re a teen. This follows yesterday’s launch of AI-based age estimation on YouTube, but it now appears that the effort reaches well beyond video recommendations.According to a new Google blog post, the same technology will start testing across a wider set of Google services in the coming weeks. It will target a small number of US users in the initial testing phase, before rolling out more broadly over time.
