Synthesia

Synthesia is an AI video platform for business communication. Instead of filming with cameras, actors, and studios, you choose an AI avatar, supply a script or a source file, and receive a narrated video. The platform also handles translation, dubbing, interactive video, and live avatar conversations for training and research. It is aimed at organizations producing high volumes of internal and customer-facing video.
