- You want videos in multiple languages
- You don't want to film or hire actors
- You're a business or enterprise user
Who Should NOT Use Synthesia

- Professional filmmakers needing cinematic quality — Runway offers Gen-4 Alpha, Motion Brush, and precise control for creative productions

Frequently Asked Questions
How realistic are the AI avatars?
Synthesia's avatars are highly realistic — most viewers can't tell they're AI-generated at normal viewing speed. The latest generation avatars have natural facial expressions, eye movements, and lip sync. Minor uncanny valley effects may be noticeable on close inspection.
Can I create my own custom avatar?
Yes. The Corporate plan and above include a custom avatar — you film a 5-minute video of yourself or a team member, and Synthesia creates an AI clone that can say anything in any language. Enterprise plans support unlimited custom avatars.
Is Synthesia only for talking head videos?
Essentially yes. Synthesia specializes in avatar-based presenter videos. You can add screen recordings, images, and text overlays, but the core output is a presenter speaking to camera. For creative/abstract video generation, use Runway or Pika.
