HeyGen
AI video platform for creating lifelike talking-avatar videos from text, audio, or images
About HeyGen
HeyGen is an AI video generation platform that produces talking-avatar videos from text scripts, audio, images, or documents, using lifelike avatars with accurate lip-sync and voice-synced expressions. Users can pick from a stock avatar library or create a custom digital twin from a short recording, then generate footage of the avatar speaking with synced facial movements. It also translates and dubs existing videos into 175+ languages and dialects while preserving tone and matching lip movements, and offers an API for programmatic video generation.
