Researchers found that 59% of the videos appearing in the first 500 posts of a newly created TikTok account’s “For You” feed were what they called “AI slop.” This share was nearly three times higher than the 21% recorded in a similar test conducted on YouTube Shorts.
The study also found that AI-generated content is particularly prevalent in videos aimed at children. Of the 2,000 videos analyzed in TikTok’s kids category, 57.4% were classified as AI slop. One of the most influential hashtags was #cartoonkids, with 97 out of 100 reviewed videos generated by AI.
Kapwing examined over 10,700 TikTok videos across 20 popular content categories. Outside of children’s content, science and education (35%), health (33.8%), and history (33.5%) have the highest concentrations of AI-generated videos. In contrast, categories such as fitness, music, and fashion are still dominated by human-generated content.
The findings come despite TikTok’s efforts to address concerns surrounding AI-generated content. In 2025, the platform launched an initiative aimed at improving AI literacy and online safety by introducing tools that allow users to reduce the amount of AI-generated material shown in their feeds.
Experts cited in the report warned that watching large amounts of inaccurate AI-generated educational videos could impact learning and development, especially among young viewers.
Qazinform News Agency previously reported that more than one in five videos shown to first-time YouTube users are generated by AI.
