Synthesia is text-script-to-video with AI avatars in 140+ languages — product demos, onboarding, and training videos without filming. It's a strong pick when: product teams producing onboarding/help videos that change as often as the product does. But it isn't right for everyone — the main reason to look elsewhere: avatars read scripts; they don't demo software. Pair with screen recording for actual UI walkthroughs.
The alternatives worth considering
- HeyGen
- D-ID
- Colossyan
- Loom (screen-first)
How to choose
Start from the limitation above. If it doesn't apply to you, Synthesia is likely the right call — for software teams the killer use is versioned product walkthroughs: update the script, regenerate, done — no re-shoot when the UI changes. If it does apply, shortlist two of the alternatives and run both free tiers/trials against one real task before paying for either.
