Turn UGC ad scripts into AI influencer videos

A button on a UGC Ad record calls the webhook once the scripts are written. The workflow sets the record's status, then turns the saved scripts and B-roll plan into one row per segment.

For each segment, an OpenAI model writes a Veo 3 prompt that pairs the line with the influencer's medium or close-up shot and the product image. The prompt and images go to Veo 3 through the Kie.ai API in 9:16. The workflow waits, checks until the video is ready, and creates a record in an AI Videos table linked to the product and the ad. When every segment is done, the status is updated.
