Real-World Use Cases

  • Corporate training
  • Onboarding
  • Product demos
  • Internal comms
  • Sales enablement
  • Localisation

What is Synthesia?

Synthesia makes presenter-led video from text. You pick an AI avatar, paste a script, choose a language, and it produces a person on screen delivering it — lip-synced, with natural gestures, in over 140 languages.

It is squarely a business tool, not a creative one. The value is in what it removes: no studio booking, no camera crew, no re-shoot when a policy changes. Edit the script, regenerate, and the video is updated.

Localisation is the killer feature. One script becomes forty language versions with the same presenter.

Benefits of Synthesia

Why L&D and comms teams standardise on it:

  • No production overhead. Script to finished video in minutes.
  • 140+ languages from a single source script.
  • Updates are trivial. Change the text, regenerate — no re-shoot.
  • Custom avatars of your own presenters or executives.
  • Brand kits and templates keep every video on-brand.
  • SCORM export drops straight into an LMS.

Who Should Use Synthesia?

Synthesia is for organisations producing volume video.

  • Learning and development teams building training libraries.
  • HR producing onboarding and compliance content.
  • Product marketing making demos and release videos.
  • Internal communications at multinational companies needing localisation.
  • Sales enablement teams personalising outreach at scale.

It is not a creative filmmaking tool — for cinematic or generative video, use Runway or Sora.

Frequently Asked Questions

Is Synthesia free?
There is a free tier with a small monthly allowance and watermarked exports, intended for evaluation. Paid plans remove the watermark and add real minute allowances.

How many languages does it support?
Over 140, with the same avatar delivering the script in each. That makes it the standard choice for multinational training and internal comms.

Can I create an avatar of myself?
Yes, on Creator and Enterprise plans. You record a short reference video and Synthesia builds a custom avatar from it.

Do the avatars look real?
They are very good and improving, but on close inspection they still read as synthetic. For training and internal comms that is generally accepted; for brand hero films it may not be.

Can I use it with my LMS?
Yes. SCORM export is supported, so videos drop into most learning management systems directly.

Is there an API?
Yes, on higher tiers — useful for generating personalised video at scale from a template and a data source.
