A report by video editing platform Kapwing says TikTok serves substantially more AI-generated “slop” to new users than YouTube. Kapwing manually reviewed 10,742 TikTok videos across 20 popular categories and also ran a fresh-account test, examining the first 500 videos served in a new user’s For You feed. In that test, about 59% of TikTok videos were categorized as AI slop, roughly three times the rate Kapwing found on YouTube using a similar fresh-account method. Kapwing reports that on YouTube, 104 of the first 500 Shorts shown—about 21%—were considered AI slop.
The analysis found especially high rates in TikTok’s Kids category, where 2,000 videos were assessed; 57% were labeled AI slop, with the highest rate appearing in tags such as #cartoonkids, where most videos were AI-generated. Other categories with notable rates included Science and Education (about 35%), Health (about 33%), and History (about 33%). By contrast, lower rates were reported in categories with more emphasis on on-camera presence or physical demonstrations, including Fashion, Music, and Fitness. The reporting also notes TikTok had already labeled billions of videos as AI-generated as of last November.
