What Is Synthesia?
Synthesia is a browser-based AI video generation platform that allows users to create professional-looking videos using lifelike AI avatars. Instead of filming a real person, users simply input a script, choose an avatar, and select a voice/language — Synthesia does the rest.
The platform is best known for:
Human-like avatars that lip-sync your text accurately
Multi-language voice synthesis with realistic tone and intonation
Drag-and-drop video builder (like slides meets timeline editor)
Unlike free-form video tools like Runway or Pika Labs, Synthesia is built around business communication: onboarding videos, how-tos, training modules, HR updates, presentations, and more. It’s built to scale video production across teams without requiring video production experience.
🧠 Fun Fact: The team behind Synthesia includes researchers from UCL, Stanford, TUM, and Cambridge — and it was originally launched as a tool for Hollywood-level video synthesis.
How Synthesia Works
Here’s a quick look at how users typically create a video in Synthesia:
Select an Avatar: Choose from 140+ AI avatars representing various ethnicities, genders, and ages. You can also create your own custom avatar (Enterprise only).
Write or Paste a Script: Your script is what the avatar will say — and you can customize the language, accent, and even voice tone.
Design Slides: Synthesia videos are structured like slide decks. You can add images, text, icons, screen recordings, and animations.
Preview & Generate: Once your slides are ready, Synthesia renders the video in the cloud and lets you download it in HD.
Share or Export: Videos can be downloaded, embedded, or shared via LMS or intranet platforms.
Each video slide contains one speaking section — this structure helps keep delivery natural and avoids avatar fatigue.
