Synthesia is an AI-powered video creation platform that transforms written text into fully produced videos using digital avatars. It removes the need for cameras, microphones, actors, or traditional editing tools by automating the entire video production process.
It is widely used by organisations that need to create high-quality videos quickly, consistently, and at scale—especially in training, marketing, and education.
What is Synthesia?
Synthesia is a text-to-video AI platform that generates videos directly from scripts. A virtual presenter (an AI avatar) delivers your script in a natural, human-like way, complete with lip-syncing, gestures, and voice narration.
In simple terms:
You write a script → AI generates a presenter → A complete video is automatically produced
This makes it possible to create professional videos without any filming, editing, or production experience.
How Synthesia Works
The platform operates through a simple four-step process:
Script Creation
- You write or paste your script into the editor
- The script becomes the foundation of the entire video
- You can use training material, marketing copy, or educational content
Avatar Selection
- Choose from a library of AI-generated presenters
- Avatars differ in appearance, tone, and style
- Options suit corporate, educational, or promotional use cases
Voice and Language Setup
- Select an AI voice and preferred language
- Supports a wide range of accents and over 100 languages
- Enables content creation for global audiences without re-recording
Video Generation
- The AI automatically produces the video
- The avatar speaks with synced lip movement and natural pacing
- Facial expressions and gestures are added for realism
