CompareAIOur verdict
Synthesia owns the corporate training niche because it solved the right problem: not 'make beautiful video' but 'make updating videos cheap.' If your backlog of outdated training content keeps you up at night, this is the fix.
Our take: pilot it on one training module that needs updating anyway. Measure the turnaround against a re-shoot — the comparison usually ends the debate.
What is Synthesia?
Synthesia turns typed scripts into videos presented by realistic AI avatars speaking 100+ languages. No camera, no actors, no filming: pick a presenter, paste your script, and get a finished video — which is why training, onboarding, and internal comms teams adopted it first.
The killer use case is scale. Updating a training video used to mean re-shooting; with Synthesia it means editing text. Companies with large course libraries or multilingual audiences save staggering amounts of production time.

Frequently asked questions
Do Synthesia avatars look realistic?
They're convincing for informational content — most viewers accept them as presenters. For emotional or high-trust content, the uncanny valley still shows.
Can I make an avatar of myself?
Yes — custom avatars can be created from your own recorded footage, subject to their verification process.
What languages does Synthesia support?
Over 100 languages and voices. One script can be rendered in many languages, which is the main reason global teams adopt it.
Is Synthesia good for YouTube content?
It works for informational and faceless channels, but YouTube audiences reward personality — AI presenters underperform real creators for entertainment content.
