Synthesia

What it does

Synthesia creates training and corporate videos with AI presenters. Write a script, choose an avatar and it produces a video in any of dozens of languages.

It is built for businesses that make lots of training, onboarding and how-to videos.

Why use it

• Consistent training videos without filming.
• Easy to update when a policy or process changes.
• Many languages from the same script.
• Brand kits and team workspaces for larger organisations.

How it works

1. Sign up in the browser and pick a template.
2. Write or paste the script, slide by slide.
3. Choose an avatar, voice and language.
4. Generate, review and share the video, or download it.

How hard is it to use?

Intermediate Some set-up, or a little practice, to get good results.

Feels like making a slide deck. Getting a natural result means writing scripts for speaking, not reading.

What it costs

Paid plans; free trial. Paid plans, priced by the minutes of video you make each month, and you can try it before paying. Enterprise plans add more avatars and controls.

Prices change often, so check Synthesia’s own site before you pay.

Watch out for

• AI presenters can feel stiff for emotional or personal messages.
• Tell viewers the presenter is AI-generated.

Your data

If you create a custom avatar of a real person, make sure they have consented and know how it will be used.

Synthesia doesn’t offer UK data storage, so check where it keeps your data before you share anything private or about other people.
