HeyGen is an AI video creation platform centered on digital presenters and script-driven production. It can turn text, images, audio, or presentation files into videos containing narration, captions, visuals, and animation. Creators can select or build an avatar, provide its script, direct tone, pacing, gestures, and emotion, then adjust text, color, timing, or layout in AI Studio without rebuilding the entire project.
The platform is designed for individual creators, marketing and sales teams, training professionals, and organizations producing localized content. Its workflows cover explainers, promotional material, product demonstrations, onboarding lessons, social clips, and visual versions of podcasts or voiceovers. Custom avatars require on-camera identity verification from the person depicted, while generated content is scanned automatically and edge cases may require review by human moderators.
