Overview
HeyGen creates presenter-led videos from scripts, prompts, images, or uploaded footage. Its product includes AI avatars, Video Agent generation, a text-based AI Studio editor, voice and gesture controls, captions, and tools for producing videos from images or audio. Video Translation can re-voice a video and synchronize lip movements across supported languages, with review and glossary options. HeyGen also offers REST APIs, CLI tooling, and an MCP server. Its public tools are integrations around the hosted service, not the avatar platform's source code.
