60% of TikTok videos are AI slop; 21% of YouTube ones

Nearly 60% of videos served to new TikTok accounts are AI-generated “slop,” according to a study by video editing platform Kapwing. The report, cited by TNW, found that AI-generated content is most prevalent in children’s categories, where 97% of videos under the #CartoonKids tag were synthetic.

Why is AI slop dominating TikTok and YouTube?

Video platforms prioritize quantity over quality in their recommendation algorithms, which incentivizes creators to flood the system with AI-generated content. Ana Maria Constantin of Kapwing notes that this structure rewards those who can upload high volumes of media rapidly, regardless of human effort or artistic value.

Kapwing’s research focused on “clearly AI-generated scripts and voiceovers.” Because the study only counted obvious synthetic markers, the actual volume of AI content is likely higher than the reported figures. This creates a feedback loop where low-effort, high-volume content pushes human-made videos further down the feed.

How does AI content vary between platforms?

TikTok shows a significantly higher saturation of AI-generated media than YouTube. According to the Kapwing data, 59% of the first 500 videos on a new TikTok “For You” page were AI-generated. In contrast, a previous study found that 21% of YouTube videos shared this characteristic.

This disparity suggests that TikTok’s short-form, rapid-fire delivery system is more susceptible to synthetic flooding than YouTube’s mixed-length format. The lower barrier to entry for short-form video allows AI tools to generate and upload content at a scale that human creators cannot match.

What are the risks for children’s content?

AI-generated content is most concentrated in videos aimed at children. Kapwing analyzed 100 videos under the #CartoonKids tag and found that 97 of them were AI-generated, leaving only three human-made videos in the sample.

Other child-centric tags showed similar trends. The #cartoons and #babysong tags both reached 83% AI saturation, while #forkids hit 79%. This suggests that creators are using AI to mass-produce simplistic, colorful content that appeals to toddlers and young children, who are less likely to distinguish between synthetic and human creativity.

What happens next for synthetic media trends?

The current trend suggests a shift toward “invisible” AI. As Kapwing only identified “clearly” synthetic scripts and voices, the next wave of content will likely use more sophisticated tools to mimic human imperfection. This will make the 59% figure a floor rather than a ceiling.

Because platforms reward quantity, the incentive remains for creators to automate as much of the production pipeline as possible. This may lead to a “trust gap” where users migrate toward verified human creators or gated communities to avoid the noise of synthetic feeds.
