YouTube to use AI to estimate users’ age and boost teen protections

YouTube announced plans on Tuesday, July 29, to roll out an AI-powered tool that estimates whether users are under 18. The technology uses machine learning to assess age based on signals such as video viewing history, content categories and account longevity — regardless of the birthdate listed in a user’s profile.

If the system identifies someone as a teen, YouTube will automatically apply additional safety measures.

What protections will apply to teen users?

For users determined to be under 18, YouTube will disable personalized ads, limit repeated views of certain videos and enable “digital wellbeing” features. YouTube will limit age-restricted content to users it verifies as adults. Users incorrectly flagged as underage can verify their age with a government ID or credit card.

When will the tool be available?

YouTube said it will begin testing the system with a small group of U.S. users in the coming weeks. The company uses the technology successfully in other regions, but hasn’t specified which ones. It plans a broader U.S. rollout after the test period, followed by expansion to additional markets.

Why is YouTube introducing this now?

The platform said the update builds on previous safety features such as YouTube Kids and supervised accounts. Company executives, including Director of Product Management James Beser, said the goal is to provide a more age-appropriate experience while preserving teen privacy.

The announcement follows a February preview by CEO Neal Mohan and comes amid rising concern over teens’ exposure to online content.

How popular is YouTube among teens?

YouTube remains the most widely used social media app among U.S. teenagers. A 2024 Pew Research Center survey found that 90% of teens aged 13 to 17 reported using the platform, compared to 63% who said they use TikTok. YouTube said it aims to uphold that trust by enhancing protections for younger users while maintaining an engaging experience.
