YouTube has started using artificial intelligence to estimate the ages of its users in the United States.

The system replaces reliance on self-declared birthdates with automated checks on account history, viewing habits, and how long an account has been active. If it decides an account belongs to someone under 18, it moves that profile into a teen category.

A teen account blocks access to age-restricted videos and runs non-personalized ads. It also switches on digital well-being tools, such as reminders for breaks or bedtime, and prompts for privacy when posting or uploading. If the system makes a wrong call, the user must prove their age to return to a standard account. This can mean uploading a photo ID, credit card details, or a selfie.

The change is meant to protect younger viewers, but many see storm clouds on the horizon. Critics warn that asking for sensitive documents can expose people to identity theft. Others are uneasy about how the information might be stored or used, especially since the company has not set out full details. While YouTube says the data is not kept for advertising, it has not confirmed whether it stays in other records.

The way the AI works has raised questions. It looks for viewing patterns linked to certain age groups. That can make sense for accounts focused on children’s shows, but it risks catching adults whose tastes overlap with younger audiences. The reverse is also possible. A teenager who prefers gardening or classical music videos might slip past the system without any flag at all.

Concerns extend to what might happen to the collected information in the long run. Privacy advocates point to the risk of profiles being shared or demanded under legal orders. Some users are already drawing a line. A petition on Change.org has passed 90,000 signatures, and many signatories say they will shut down their accounts if verification becomes a condition of use.

For now, YouTube is continuing with the rollout after trials overseas. The outcome will show whether the AI-driven checks become a fixture or face changes under public pressure.
