Synthesys

Synthesys turns scripts into presenter videos using AI avatars and natural text-to-speech, for training, marketing, and explainers without a camera.

Overview

Synthesys combines two engines: a library of realistic human avatars and a voice engine with hundreds of voices across many languages. Type or paste a script, choose an avatar and voice, and the platform renders a video of the presenter delivering the content with natural lip sync. Teams localize videos by swapping the voice track into another language while keeping the same avatar, which makes scaling global training content dramatically cheaper.

Marketing teams localize explainer videos by swapping voice tracks rather than re-recording, which turns one video into a dozen markets for a fraction of the cost. The avatar library covers varied presenter styles, and the script-first workflow keeps revisions cheap.

Marketing teams localize explainers by swapping voice tracks instead of re-recording, turning one video into a dozen markets at a fraction of the cost. The avatar library covers varied presenter styles, and the script-first workflow keeps revisions cheap and fast.

Avatar and voice libraries keep expanding, and the rendering turnaround supports rapid iteration on scripts. For internal communications and training, the ability to update a single line of script without reshooting is the feature teams cite most.

Pricing

Synthesys sells paid subscriptions tiered by video minutes and avatar access; plans are aimed at individuals and teams rather than enterprise custom avatars.
