Definition
Synthesia is an AI video generation platform that turns text scripts into videos featuring realistic AI avatars speaking in dozens of languages, without cameras, actors, or studios.
Overview
Synthesia is best known for enabling anyone to produce professional-looking videos by simply typing a script and selecting an AI avatar and voice. It is widely used for corporate training, onboarding, product explainers, and localized marketing content, since the same script can be dubbed into many languages using synthetic voices generated by text-to-speech style models built on deep learning. Under the hood, Synthesia combines generative video models with voice synthesis: a user's text is converted to speech, and a neural rendering pipeline animates a photorealistic avatar's lip movements and expressions to match. Businesses can also create a custom avatar of a real presenter for repeated use across many videos. Synthesia competes with other AI video and avatar tools such as HeyGen and sits alongside broader generative video tools like Runway and Pika, though its focus is specifically on talking-head, presenter-style content rather than cinematic scene generation.
