HeyGen

HeyGen makes videos with AI presenters. You can pick from a large library of avatars, turn a photo into a talking presenter, or create a digital version of yourself, then type the script and let the avatar speak it. Its video translation feature re-voices an existing video in another language using a clone of the speaker's voice and adjusts the lip movements to match. That makes it popular for training videos, marketing and creators who want to reach other languages without reshooting.
