AI avatar UGC video for ad creative the agent ships at scale
HeyGen is a hosted platform for generating AI avatar video. In a marketing agent stack it is the creative layer for UGC-style ad spots: the agent researches pain points, writes the script, and calls HeyGen's API to render avatar video for the winning angles. Closed-source SaaS with no self-host equivalent.
