HeyGen

HeyGen is transforming video production by enabling anyone to create professional videos with realistic AI avatars in minutes instead of days. No cameras, studios, actors, or editing skills required -- just type your script, choose an avatar, and HeyGen generates a polished video with natural lip-sync, gestures, and expressions. It's the future of scalable video content.

The technology behind HeyGen is remarkable. The avatars aren't just mouths moving to audio -- they have natural head movements, eye contact, hand gestures, and facial expressions that make them feel genuinely human. Combined with voice cloning technology, you can create a video "spokesperson" that looks and sounds like you, which you can then use for unlimited content without ever recording yourself again.

How It Works

Start by selecting from HeyGen's library of over 100 diverse AI avatars, or create a custom avatar from a short video of yourself. Write or paste your script in any of 40+ supported languages. Choose a voice from the library or clone your own voice with just a few minutes of audio samples. HeyGen's AI then generates your video, complete with natural lip-sync, gestures, and the avatar "speaking" your script. Add backgrounds, music, and branding elements. The whole process takes minutes, not hours.
