The news: YouTube will start automatically adding labels to videos with significant AI use even when creators don’t disclose it, the company shared in a blog post. The labels will appear above descriptions on long-form videos and as an overlay on Shorts.

Creators can dispute incorrect labels through YouTube Studio, except for content made with Veo or Dream Screen or carrying C2PA metadata that confirms full AI generation.

The labels arrive on the heels of YouTube’s likeness-detection program that lets users upload photos to the tool to find any deepfake content with their images and request deletion.

Why this matters: AI content is piling up on YouTube, one of the internet’s largest sources of user-generated content, and viewer patience is wearing thin.

• More than 1 in 5 videos recommended by YouTube's algorithm are low-quality AI slop, per Kapwing.
• About half (49%) of US adults would use social platforms less or stop altogether if AI content increased in their feeds, per Story Radius.

Consumers expect disclosure when AI shapes what they watch.

• 57% of Gen Z and millennial consumers want advertisers to disclose when an ad uses AI-generated video, more than for any other AI format, per IAB.
• Among those consumers, 73% said knowing an ad was made with AI would increase or not change their likelihood of purchase, suggesting disclosures can have positive effects.

The trust stakes are rising as spending climbs—79% of marketers increased AI investment over the past year and 77% plan to shift budgets from traditional creator content toward AI-driven campaigns, per Billion Dollar Boy.

Implications for marketers: The automatic labels take AI disclosure on content out of brands’ direct control, opening the door for surprise AI labels if a creator leaned on genAI tools without informing the brand or inaccurate ones on videos with little or no AI content.

• Brands should audit how much AI their creator partners use before and during campaigns so they can measure the effects of prominent AI labels and dispute inaccurate ones.
• They should also continue disclosing AI use directly, regardless of YouTube’s automatic tagging, since clear disclosure supports both purchase intent and trust.
