Synthesia
AI avatar videos from a script: training, onboarding, and product explainers in 140+ languages, no camera.
Synthesia turns a script into a presenter-led video: choose or clone an avatar, paste text, get a polished talking-head video with slides in minutes, localized into more than 140 languages. Enterprises adopted it for training and internal comms at a scale no studio could price-match.
The updated avatars have crossed the believability line for corporate content. It is not for cinematic creative; it is for the mountain of instructional video every company needs and never films.
