Synthesia Review (2026)
Making a professional video usually means a camera, a presenter, lighting, and editing. Synthesia removes all of that: you type a script, pick an AI avatar, and it generates a polished talking-head video — in 140+ languages. For training, onboarding, and explainer content, it's a genuine time-saver. Here's our review.
What is Synthesia?
Synthesia is an AI video platform that turns text into video using realistic AI avatars and natural-sounding voiceovers. You choose an avatar, paste your script, and Synthesia produces the video — no filming required. Need a change? Edit the script and re-generate, instead of re-shooting.
Who is Synthesia best for?
- Teams making training, onboarding, and explainer videos.
- Anyone who needs videos in many languages.
- Creators who want to update videos by editing a script, not re-filming.

Pricing
Synthesia's paid plans commonly start around $18–29 per month, scaling up for teams and more video minutes. For the volume of professional video it produces, that's reasonable — filming the equivalent would cost far more. If you need images instead of video, see Adobe Firefly; for the scripts themselves, a writer like Jasper pairs well. Confirm current pricing on Synthesia's site.
Our verdict
Is Synthesia worth it?
For training, onboarding, and explainer videos at scale — especially across languages — Synthesia is excellent and hard to replicate any other way. If you need cinematic footage or emotionally nuanced acting, it isn't the tool. But for its lane, it's one of the best.
