HeyGen enables businesses and creators to produce professional talking-head videos using AI avatars — either from their own likeness or from a library of stock presenters — without cameras, studios, or video editing skills. Its video translation feature can dub existing videos into dozens of languages while keeping the speaker’s voice and lip movements in sync, opening up multilingual content at scale. HeyGen is widely used for corporate training, product explainers, and personalised sales outreach videos.
