HeyGen makes explainer videos with an AI avatar of you

So updating a demo video means editing text, not booking a reshoot.

The problem

Product demos, FAQ videos and ads need you on camera, and re-shooting every time something changes isn't realistic.

What it is, what it does

HeyGen turns a typed script into a video of a talking AI avatar, including a custom avatar based on you. It can import slides, clone your voice on paid plans, and translate videos into other languages.

Workflow

1Create a custom video avatar of yourself in HeyGen (or use a stock avatar)
2Paste a short script or import slides from PowerPoint or PDF
3Generate the video, then tweak the script and regenerate instead of re-filming
4Translate it into other languages for new markets and publish to your site or socials
