Synthesia

Synthesia is an AI video platform based in London. It was founded in 2017 by a team of researchers and entrepreneurs from University College London, Stanford and the Technical University of Munich. It turns a written script into a video with a realistic presenter, without cameras or actors.

Users choose from a large set of stock avatars or create a custom avatar of a real person with consent. Videos can be made in many languages, and one video can be translated into others. Templates, a screen recorder and brand kits help companies keep videos consistent. Synthesia has strict rules on what avatars can say. Videos can be shared through a link, embedded in learning systems or downloaded.

There is a free plan with a few minutes of video. Paid plans give more minutes and features, and Enterprise plans add collaboration, security and custom avatars. Large companies use it mostly for staff training, onboarding, product explainers and internal updates.
