Easier to evaluate for freeNhận định biên tậpBoth are real free tiers, and both stop short of a shippable deliverable. Synthesia's is denominated in output minutes, which is the unit the person approving the project already thinks in, and its output carries the Synthesia logo until you upgrade. HeyGen's free output is licensed for personal, non-commercial, internal evaluation only, so nothing produced on its free plan can be shipped either. On evaluation alone, the minute-denominated allowance is easier to act on.

Three clips, one minute each
Breadth of language supportNhận định biên tậpThe countable numbers have to decide this row. Synthesia's pricing page publishes 160+ languages and voices across its plans, and 70+ dubbing output languages on Basic through Creator, while HeyGen's free card prints 30+ languages. HeyGen markets translation and lip sync as a headline capability, and on the published counts Synthesia is the wider one. We have not measured output quality in either.

Chọn Synthesia nếu
You need to produce a finished module and judge whether avatar video fits the way you work. Ten minutes of video a month is an evaluation budget you can plan around, and it is denominated in the same unit your stakeholder thinks in. Its entry price matches HeyGen's, and its published language counts are the larger ones on the page. Free output carries the Synthesia logo until you upgrade.
HEChọn HeyGen nếu
You are judging whether AI avatars are good enough at all, and you want the translation headline. Three one-minute clips answers that question quickly, but free output cannot be shipped: it is watermarked and licensed for personal evaluation only.

Both of these turn a script into a video of a presenter who does not exist. They overlap enough that most teams will only buy one.
Rows marked Editorial call are our judgment and carry the reasoning. The fact rows carry two published figures with the pages they came from, and you can check both in under a minute.
We have not compared output quality. Doing that honestly would mean generating the same script through both and having somebody who is not us judge the result, and we have not done it. What we can compare is what each vendor lets you produce before paying, which is the thing that decides which one you try first.
Both entry prices now appear in the table, and they match: Synthesia's Starter and HeyGen's Creator both list $29 a month, and each page carries the USD figure in its data. The old note about neither entry price appearing is gone because HeyGen's pricing page stops being unreadable the moment you read its underlying data, which names the currency. The comparison no longer needs to send you to the vendor's page to learn what each charges before committing.
The language row changed direction. The previous version called this for HeyGen on the strength of its marketing, and the published counts do not support that call: Synthesia prints 160+ languages and voices across its plans and 70+ dubbing output languages on Basic through Creator, against a 30+ figure on HeyGen's free card. The row now says what the numbers say, and the editorial call is confined to what HeyGen markets harder.
The free tier story is now symmetric on shipping: both free outputs stop short of a deliverable, one with a watermark and one with a license term, and the evaluation row says so on both sides. Synthesia's ten minutes of watermarked video is an evaluation of the product itself; HeyGen's three clips are the same evaluation with a different ceiling.
The two reviews read the boundaries in full: the Synthesia review weighs ten minutes of finished video against a watermark, and the HeyGen review reads the ownership sentence next to the license HeyGen takes. The profiles carry the same figures behind each column: Synthesia and HeyGen.
