HeyGen

HeyGen creates videos with talking avatars from a script: virtual presenters, corporate training, multilingual content, and voice dubbing. 300+ avatars and the option to clone your own voice for custom videos.

Features include templates by industry, auto captions, and translating videos into other languages while keeping lip-sync. Used for marketing, onboarding, tutorials, and internal comms. Free trial, then credit-based or subscription plans. Compare with Synthesia or Colossyan for AI avatar video.
