What is Synthesia?
Synthesia is an AI video platform that generates videos of realistic AI avatars presenting your script, in 140+ languages, with templates and a simple editor. It targets businesses making training, onboarding, and explainer videos at scale without filming.
What Synthesia does well
AI avatars
Choose from 140+ realistic presenters (or create a custom avatar) that speak your script — no camera, crew, or studio needed.
Multilingual at scale
Produce the same video in dozens of languages instantly, ideal for global training content.
Template-driven editor
Slide-and-script templates make producing polished corporate video fast for non-editors.
Where it falls short
Avatars, while good, can still read as slightly artificial for emotional storytelling, and it is priced for business rather than hobbyists. It is not for cinematic or footage-based video.
Synthesia hands-on
For an explainer, Synthesia turned a script into a polished presenter video in minutes — something that would normally need filming. The avatar was convincing for corporate use, if not for emotive storytelling. For training content without a camera, it is excellent.

Synthesia in practice: an explainer video
We turned a script into a presenter-led explainer in minutes — pick an avatar, paste the script, add slides, done — no filming, crew, or studio. The avatar was convincing for corporate use, and generating a second language version was a couple of clicks. It is not for emotive storytelling, but for training and explainer content that would otherwise need a shoot, the time and cost savings are dramatic.
Synthesia for different use cases
- Training & onboarding: Presenter videos at scale without filming.
- Corporate comms: Consistent internal and external messaging.

Is Synthesia worth it?
At around $29/month, Synthesia is priced for business, and that is where it pays off — replacing filmed training and explainer video with something you can update in minutes saves far more than the subscription. For a solo creator making the occasional video it is less compelling; its value scales with how much presenter-style content you produce.
