Synthesia creates professional videos using photorealistic AI avatars that speak in over 120 languages with natural expressions and gestures.

It generates videos by converting your script into avatar-led presentations with synchronized lip movements, realistic gestures, and multilingual voiceovers. You can customize backgrounds, add branded elements, and produce localized versions simultaneously across dozens of markets.

Its instant translation feature lets you create a single video and automatically generate versions in multiple languages—each with native-speaking avatars and culturally appropriate delivery.

For marketers, it's especially useful for creating training materials, product explainers, and customer onboarding videos at global scale without managing translators, voice actors, or international video crews.
