What is Synthesia?
Synthesia is an AI video platform that turns a script, document, prompt, link or PowerPoint file into a narrated video featuring AI avatars. Users pick from a library of avatars, customize outfits and backgrounds, or create a personal avatar from a single photo. The platform also offers AI Video Dubbing and translation into 130+ languages with voice cloning and lip-sync, as well as a screen recorder and motion graphics.
Beyond standard video, Synthesia offers Sessions: live, interactive roleplays where learners practice conversations with avatars that push back, and conversational surveys that collect feedback through an avatar interviewer. Teams can use it to produce training, compliance, product and SOP videos, and to publish them via share links or download them for an LMS. An API is also available for generating and translating videos programmatically.
