Synthesia

What is Synthesia?

Synthesia is an AI video generator that produces presenter-led videos from a script, PDF, PowerPoint, web link or plain prompt, with no camera or crew. You pick from a library of AI avatars, edit scenes much like slides, apply a Brand Kit, and export finished videos. The AI Video Assistant drafts a multi-scene video from your text, and Syren, its video agent, builds a video from a description. Voiceovers and captions cover 140+ languages, and AI Dubbing translates existing video into 70+ languages on self-serve plans. Teams use Synthesia for training, onboarding, internal communications and product explainers, and can add interactive surveys and roleplay practice. Synthesia pricing starts with a free Basic plan, then Starter at $29 per month and Pro at $89 per month, both billed monthly, with a custom Enterprise plan. All plans run on a shared monthly pool of credits.
