HeyGen

HeyGen produces videos without a camera, a studio or a presenter. The user writes or pastes a script, or uploads a presentation or a PDF, chooses an avatar and a voice, and the product generates a video in which the avatar speaks the text with matching lip movement. Avatars can be picked from a library or created from a person's own footage or photo. A text-based editor, AI Studio, adjusts tone, gestures and scenes, and the translation tool dubs an existing video into other languages while keeping the speaker's voice and lip-sync. It is used by marketing, training, sales and communication teams for explainers, onboarding and localized content.
