The short verdict
Synthesia turns scripts into professional presenter-led videos with AI avatars — ideal for training, onboarding and product explainers.
Our Synthesia review
London-headquartered Synthesia is one of the UK's AI success stories. Type or paste a script, choose an avatar and voice, and it produces a presenter-style video in dozens of languages. Updating a training video means editing text, not reshooting.
It suits onboarding, compliance training and how-to content. Custom avatars of your own staff require their explicit consent.
