HeyGen
Create AI videos with lifelike avatars and voice cloning
HeyGen renders talking-head AI videos in up to 4K resolution with automatic lip-sync matching across 40+ languages.
HeyGen is an AI video generation platform that lets users create professional videos using realistic avatars and voice cloning technology. The platform generates talking-head videos where AI avatars deliver scripts with natural facial movements and lip-syncing. Users can choose from over 100 pre-built avatars or create custom avatars that look like real people, then pair them with voiceovers in 40+ languages with automatic lip-sync matching. The platform handles the entire video production workflow - from script input to final render - without requiring cameras, actors, or editing skills. HeyGen's core technology combines 3D face modeling with speech synthesis to produce videos where avatars appear to naturally speak the provided dialogue. The platform includes a script editor, teleprompter mode, and team collaboration features that let multiple users work on projects together. Videos render in up to 4K resolution with background music and text overlays available as customization options.
