Introduction

Corporate learning and development teams have long struggled with the same challenge: producing professional training videos quickly, affordably, and in multiple languages. Synthesia has built its entire product around solving that problem. Since launching in 2017, it has become the go-to AI video platform for L&D teams, HR departments, and corporate communications professionals. This Synthesia review examines whether the platform’s 2025 feature set justifies its positioning as the enterprise standard for AI-generated video.

What Is Synthesia?

Synthesia is an AI video generation platform that converts text scripts into professional-quality presenter videos using photorealistic AI avatars. Users write or paste a script, select an avatar and language, customize the video layout, and export a finished video — no camera, crew, studio, or editing skills required.

AI Avatars: 230+ Options

  • Stock avatars: 230+ professionally photographed presenters spanning diverse ethnicities, ages, and professional roles
  • Custom avatars: Enterprise customers can create a branded digital twin with a 30-minute consent recording session
  • Expressive avatars: A newer tier that adds subtle emotion and gesture variation for more engaging delivery

Multilingual Support: 130+ Languages

Synthesia supports over 130 languages with AI-generated voiceovers, making it the platform of choice for multinationals producing global training content. For a training video produced in English, generating Spanish, French, and Mandarin versions takes minutes rather than days.
