What Synthesia is for
Synthesia generates videos of a presenter speaking a script you wrote. There is no camera, no microphone and no editor. You pick an avatar, paste a script, choose a language, and export.
That sounds like a toy until you are the person responsible for rolling out the same onboarding content to offices in six countries, in four languages, by the end of the quarter. Then it sounds like the only option that fits.
Where Synthesia is genuinely strong
Consistency across a programme
The failure mode of cheap avatar tools is drift — one module's presenter looks subtly different from the next, and a 12-module course starts to feel like it was made by twelve different people. Synthesia holds a single avatar and voice steady across an entire programme. For training content that consistency is the whole point.
Language coverage that survives contact with reality
Over 140 languages and accents, with lip sync good enough that viewers stop noticing. For localisation work this removes the usual choice between subtitling (cheap, ignored) and re-shoots (expensive, slow).
SCORM and LMS export
Most AI video tools stop at an MP4. Synthesia exports into learning management systems, which means completion tracking actually works. If your training has to be auditable, this is not a nice-to-have.
Where it hurts
Cost per finished minute
The subscription price is not the real price — the real price is what you pay per shipped minute once revisions are counted. At team scale, Synthesia is comfortably more expensive than a creator tool, and the gap widens with volume.
Creative ceiling
You cannot do interesting camera work, custom motion graphics or anything that does not fit the presenter-plus-background format. Every Synthesia video looks like a Synthesia video. For internal communications that is fine; for anything brand-facing it becomes a constraint.
What it costs
| Plan | Price | What you get |
|---|---|---|
| Basic | $0 | Small monthly allowance, enough to evaluate the workflow |
| StarterPick | $18/mo | Billed annually; $29/mo month-to-month |
| Pro | $89/mo | Billed monthly; higher volume and more avatar options |

Who should skip Synthesia
Skip it if you want generative, cinematic footage — Synthesia does not do that, and Runway does. Skip it if you are a solo creator on a budget, because the price only makes sense against the cost of the studio time it replaces. And skip it if brand distinctiveness matters: the house style is very recognisable.
How we tested
We built a six-module onboarding sequence with Synthesia, including one module localised into three languages, and exported to SCORM for an LMS check. We evaluated avatar consistency across modules, lip-sync quality at speed, and how long a non-editor took to produce the first usable module. Pricing was re-checked against the official page on the date shown above.
Pros and cons
What we like
- The most consistent avatar quality in this category
- 140+ languages and accents, with credible lip sync
- SCORM and LMS export for real training deployments
- Non-editors can produce usable video on day one
What to watch out for
- Expensive next to creator-focused tools
- Cost per finished minute is high once you use it heavily
- Almost no creative control — this is not a filmmaking tool
- Output has a recognisable corporate look that is hard to escape
Our verdict
Synthesia is a business tool wearing the clothes of a creative one. Judged as a video generator it looks expensive and limited; judged as a way to ship 40 consistent training modules in nine languages without booking a studio, it is cheaper than any alternative. Buy it for the workflow it was designed for and it is excellent. Buy it to make YouTube videos and you will be disappointed.
Best for: L&D and enablement teams that need consistent training video in many languages.
