HeyGen is a browser-based video platform that produces presenter-led videos from a script or a prompt, using either stock AI avatars or a custom avatar trained on your own footage and voice. It is widely used for marketing clips, product explainers, and localized versions of existing videos.
Avatar V is the company’s newest avatar model, with Avatar IV still available, and the paid Creator plan opens a library of more than 700 stock avatars plus a custom video avatar built from your likeness. Video Agent generates a complete video from a text prompt, adding presenter footage, motion graphics, and B-roll that remain editable in AI Studio without re-rendering. Video translation clones the original speaker’s voice and syncs lip movement, working from an uploaded file or a YouTube link. Developers get APIs for Video Agent, video generation, translation, and lip-sync, and there is also a ChatGPT plugin and a LiveAvatar product. Creator exports 1080p videos up to 30 minutes long, and Pro adds 4K output and first access to new models.
Marketing teams, course creators, and businesses producing many short videos in several languages are the core audience. Usage is metered in credits, and consumption varies with the model, video length, and complexity, so heavy users of the newest models should estimate costs before committing. The free plan is limited to three watermarked videos of up to one minute per month.
