What is Synthesia?
Synthesia is an AI video generation platform used by more than 50,000 teams to produce polished video from plain text. Instead of booking studios, cameras, or editors, you type a script and an expressive, customizable AI avatar delivers it on screen. It is built for organizations that need a steady stream of on-brand video — training, explainers, internal updates — and for enterprises with strict legal and security requirements.
This review covers what Synthesia actually does, where it excels, and the trade-offs to weigh before committing.
Synthesia is a browser-based AI video generator that converts written scripts into videos fronted by customizable AI avatars. You provide the text, choose an avatar, voice, and layout, and the platform renders a finished presenter-style video — no filming equipment, on-camera talent, or video-editing expertise required. Creation, collaboration, and publishing all happen inside a single, secure environment designed to meet demanding enterprise standards.
