Best for: Companies producing training and product video that gets updated often
The default for corporate video that has to exist in ten languages and change every quarter. Count the minutes against a year of real output, because that allowance, not the seat price, decides the tier.

What is Synthesia?
Synthesia turns a written script into a finished video with a presenter on screen, no camera and no studio.
You pick an avatar from a stock library or record your own, paste the script, choose the language, and get a video where the lip movement matches the words.
The whole product is built around corporate video that has to be updated: training modules, product explainers, internal announcements. Change one paragraph and you regenerate that section rather than rebooking a shoot. Localization is where it pays for itself.
The same script renders in more than a hundred languages with the same presenter, which turns a translation budget into a dropdown. AI Dubbing does the same to a video you already have.
The editor is closer to a slide deck than a timeline, with templates, brand kits and screen recording, so people who make decks can make videos.
Minutes are the meter: free gives 10 a month, Starter $29 gives 120 a year and Creator $89 gives 360, with Enterprise unlimited.

Synthesia key features
Script to video with a presenter
Paste a script, pick an avatar, and get a video with lip movement matched to the words, without a camera or a studio.
140+ languages
The same script and the same presenter render in more than a hundred languages, which replaces most of a localization budget.
Custom avatars
Record your own presenter once and reuse them across every video, so the face stays consistent as the content changes.
AI Dubbing
Translates an existing video and regenerates the audio, with a per-year minute allowance shared with video creation.
Slide-style editor
Templates, brand kits and screen recording in an editor closer to a deck than a timeline, so non-editors can produce.
Regenerate on edit
Change a paragraph and only that section is rebuilt, which is what makes it viable for content that gets updated.
Interactive and branded video pages
Creator plans add branded hosting pages and interactive elements for training and onboarding flows.

Synthesia FAQ
Is Synthesia free?
There is a free plan with 10 minutes of video a month and 25 AI video assets, but downloads are locked. Starter at $29 per month, or $18 annually, adds them.
How much does Synthesia cost?
Starter is $29 per month, or $18 billed annually, for 120 minutes of video a year. Creator is $89, or $64 annually, for 360 minutes. Enterprise is quoted with unlimited minutes.
How many languages does Synthesia support?
More than 140. The same script and the same presenter render in each one, which is what makes it a localization tool rather than only a video tool.
Can I create an avatar of myself?
Yes. You record a short piece to camera and the avatar is built from it, with documented consent required from the person filmed.
Synthesia or HeyGen?
Synthesia for corporate training and localized content at scale, with the stronger enterprise controls. HeyGen for social and marketing video, cheaper at entry and stronger on lip-sync translation.
Does Synthesia have an API?
Yes. The API generates videos programmatically, which is how teams wire it into an LMS or a product release process.
