One crossing point, twenty-nine dollars, two nouns
Two entries cross at twenty-nine dollars a month. One removes a watermark and the other removes a logo, and only one of those is the word a reader would search for. As of 2026-09-22.
| On this question | Synthesia | HeyGen |
|---|---|---|
| The crossing point | Twenty-nine a month, eighteen yearly | Twenty-nine a month |
| What the plan removes | The Synthesia logo | A watermark |
| Found by a term search | No | Yes |
| Free plan bound by | A feature list with the line absent | Three videos a month |
| File contents | Nothing published | Nothing published |
Inclusion rule. One row per question on which these two entries can be compared from their own published pages. Questions neither vendor addresses are left out rather than filled with a dash. Order. Fixed order: the mechanism first, then who holds it, then what it leaves behind.
| Generator | Paid tier | Document read |
|---|---|---|
| HeyGen | Removal from Creator ($29/mo) | pricing page |
| Synthesia | Remove Synthesia logo from Starter ($29/mo) | pricing page |
Inclusion rule. The two entries on this page, with the value each one's own pages support in the column they diverge on. Order. Alphabetical by generator name.
1The same figure, arrived at the same way
Both entries print a plan grid, both attach the marking line to their entry paid tier, and both name twenty-nine dollars a month. On the crossing point itself there is nothing to choose between them, which is what makes the rest of the comparison legible: everything that differs here differs in the writing rather than in the packaging.
One prints a second figure, eighteen a month billed yearly, which is the widest annual discount on any priced row in this register. The other prints one figure and a credit allowance. A reader quoting a crossing point across these two rows is quoting on two different bases unless they say which.
2A vocabulary difference that decides who finds the page
One vendor's grid never uses the word watermark. The mark is named as its own brand plus the word logo, and the paid feature is the removal of it. The behaviour is identical to its neighbour's; the term is not, and a question asked with the standard word does not match the page.
That is a live problem when most such questions are asked of software. A vendor documenting a behaviour under a word nobody queries is systematically absent from answers about it. The register keeps the vendor's own noun and records the substitution as a separate fact rather than normalising it away.
3Where each free plan leaves a reader
Both free cells are omissions: the marking line sits against the paid columns and not the free one. One free plan is additionally capped at three videos a month of up to a minute each, so the clean file and the working allowance arrive together and crossing the boundary is not really a marking decision.
Neither vendor names a provenance standard, a metadata field or a detection route, so both record not documented for file contents. Two products whose output is a synthetic person speaking, both describing what a plan removes and neither describing what a file carries.

Both values above are read from the vendor pages linked in the rows: synthesia.io and heygen.com, on 2026-09-22. Each entry has its own page, Synthesia and HeyGen, and the rule for the column they diverge on is on the paid tier column page. Other pairs: marking and licence, crossing points with no figure.
