YouTube launched a new artificial intelligence system in the United States on August 13, 2025, to estimate whether viewers are adults or minors by examining the types of videos they watched. The initial phase involved only a small portion of viewers but was expected to expand nationwide if results matched the system’s previous performance in other countries. The AI check operated only for logged-in users and assessed ages regardless of the birth date provided during account creation. YouTube, owned by Google for nearly two decades, applied its existing safeguards when the system determined that a viewer was under 18.

These safeguards included reminders to take breaks from the screen, privacy alerts, and blocked access to certain video recommendations. Ads tailored to personal preferences were also disabled for accounts identified as belonging to minors. If a viewer was incorrectly classified, age could be verified using a government-issued ID, a credit card, or a selfie. Experts indicated that the goal was to enhance safety protections while maintaining user privacy. Some digital rights organizations expressed apprehension about potential effects on personal data and freedom of expression. Despite these contentious discussions, YouTube’s proactive adoption of AI in this area was seen as a paradigm shift in age control technology, providing a more robust safeguard for younger audiences and supporting a safer online environment.
