HeyGen is a business-focused AI video platform built around talking avatars, synthetic voices, localization, and prompt-led video assembly. Its breadth stands out: users can start from a script, prompt, URL, image, audio file, PDF, or source video, then refine the result in AI Studio. It is particularly compelling for marketing, sales, training, and multilingual video teams; creators who need detailed cinematic shot control or HDR delivery will run into notable limitations.
