Definition
HeyGen is an AI video generation platform that creates talking-head videos of realistic digital avatars from text scripts, and offers AI-powered video translation and dubbing that preserves a speaker's likeness and voice across languages.
Overview
HeyGen lets users generate videos of a presenter — either a stock digital avatar or a custom avatar trained on a real person's likeness — speaking a script typed or pasted into the platform, without needing to film new footage. This makes it popular for producing training videos, marketing content, and product explainers quickly and at lower cost than traditional video production. A notable feature is AI-powered video translation and dubbing: HeyGen can take an existing video of a person speaking and generate a version in another language where the lip movements and voice are adapted to match, aiming to preserve the original speaker's likeness and delivery. This combines generative video with the kind of voice technology seen in tools like ElevenLabs. HeyGen competes with other AI avatar and video-generation tools such as Synthesia, and its capabilities have contributed to broader conversations about deepfakes and consent, covered in discussions of AI safety and ethics.
