UGC-style ads look like what people already watch on TikTok, Reels and Shorts: someone talking to camera in plain language about a product. They interrupt the feed less than a polished spot, which is why many advertisers lean on them for short campaigns.
The catch is that performance depends on the hook and the angle, and nobody knows the winning angle before testing. That is where AI helps: more versions, faster, for less than filming every version with a creator.
