What Is Synthesia?

Synthesia is an AI video generation platform that converts text, documents, or URLs into fully rendered videos featuring virtual characters. Users can choose from a library of avatars or create custom ones, then dictate the tone, pacing, and voice style. The underlying technology employs transformer‑based models to generate speech that aligns with lip‑movement, ensuring a natural look even when dubbing into multiple languages. The platform is entirely cloud‑based, so all processing happens on Synthesia’s servers, and the finished videos are downloadable or shareable via a link.

Multilingual Support – Create content in 130+ languages, with AI dubbing that preserves lip sync.
Document‑to‑Video – Convert PDFs, PowerPoint slides, or web pages into video format automatically.
