What is Synthesia?

Synthesia is one of the leading AI video platforms for business. You write or paste a script, choose an AI avatar and voice, add slides, screen recordings and images, and Synthesia produces a presenter-led video. It’s used by many large companies for training, onboarding and internal communication because videos are fast to produce, easy to update and simple to localise into other languages.

Key features

  • AI avatars. Choose stock presenters or create a personal avatar.
  • Voices and languages. Generate narration in many languages and accents.
  • Slide-based editor. Build videos scene by scene like a presentation.
  • Templates. Start from layouts for training, how-to and sales videos.
  • Translation. Create localised versions of a video.
  • Collaboration. Comment, share and manage brand kits as a team.
  • Screen recording. Combine avatars with product walkthroughs.

Who Synthesia is for

HR and learning & development teams, customer success teams creating help videos, product marketers, compliance trainers and international companies that need the same content in multiple languages.

Tips for effective training videos

  • Keep scenes short, one idea per scene.
  • Write the way people talk and check speaking time with the free word counter.
  • Track script changes between versions with the text compare tool so reviewers only check what changed.
  • Use consistent titles; fix capitalisation with the case converter.

Synthesia vs alternatives

HeyGen is more popular with marketers and creators and strong at video translation. Descript is better if you record real people. Gamma creates presentations rather than videos. InVideo AI builds videos from stock footage for social media.

Is Synthesia worth it?

For companies producing training or explainer videos regularly, Synthesia can cut production time from weeks to hours and makes updates painless. Individuals making occasional creative videos will find other tools more flexible. Test the free plan with one real training module to judge the result.
