AI tool overview
HeyGen creates scripted videos with AI avatars and voices, using scene-level controls for narration, background, and presentation.
HeyGen is an AI video product focused on scripted avatar presentations. Its official AI Studio guide explains that a creator starts with a script, adds scenes, and assigns an avatar, voice, and background to each part of a video. The guide also describes previewing narration before submitting a project. This structure fits explainers, onboarding videos, and social clips where a spoken message needs a visual presenter. HeyGen separately documents video translation, including audio-only and lip-sync modes, but availability depends on the current product configuration. Creators should review the final speech, captions, identity permissions, and visual accuracy before distributing a generated video.
Plans and availability can change. Check the official website for current details.
HeyGen's AI Studio guide explains that each scene can have its own script and assigned avatar, voice, and background.
