What is Synthesia?
Synthesia is a web-based AI video platform designed for business communication, training, sales, and customer support. It turns prompts, documents, presentations, and web links into videos featuring AI avatars, generated voiceovers, motion graphics, and scripted scenes. Users can choose stock presenters, create customizable avatars, or build a Personal Avatar from a photo or short video.
The platform covers video creation, translation, publishing, management, and performance measurement. It also provides interactive avatar sessions for roleplay and surveys, plus APIs for generating videos, dubbing content, and adding conversational avatars to other products.
