How a field on this site gets filled in

Four fields per generator, the same four for everyone: free tier, paid tier, control, and machine-readable marking. A field is filled only from the vendor's own public pages, and a field the vendor does not publish is recorded as not documented. As of 2026-09-12.

1The four fields

Free tier and paid tier record what the vendor states about output on each side of the paywall. Most vendors state this in a plan comparison, as a feature that a plan includes or omits. Where a plan table carries the line under every plan and distinguishes them only by an icon, the icon is what is read, because that is what the page means.

Control records how the mark is removed, which is a different question from whether it can be. Two shapes appear: a plan benefit, where paying changes the output, and a setting, where the user switches it. The distinction matters to anyone collecting footage from several contributors, because a plan benefit makes the deliverable depend on who generated it.

Machine-readable marking records what the vendor says is written into the file. A named standard, a named metadata field or a described signal counts. A general reference to metadata without fields does not, and is recorded as not documented with the sentence that prompted the question kept on the generator's own page.

2What not documented means here

It means the vendor's public pages do not state it. It is not a claim that the product does nothing, and it is not a negative finding about the product. Vendors write provenance data without describing it, and the only thing a record like this one can honestly track is what is written down.

The reason to record it as its own state, rather than leaving a blank, is that the absence is itself the answer to a question people ask: whether the tool tells you what it writes into your file. A blank cell reads as an oversight; a stated not documented reads as what it is.

3Dates

Two dates travel with every field: when the value was first written down, and when it was last compared against the vendor page. Comparing and finding no change advances the second one, because the useful question is when somebody last looked rather than when the answer last moved.

Page dates behave differently and deliberately so. Rebuilding this site does not touch them, so a date under a heading means an editor changed something.

4Corrections

Where a vendor page and a row here disagree, the vendor page wins and the row is changed. Where two pages from the same vendor disagree with each other, both are recorded with their dates rather than one being chosen. Nothing on this site states whether a product complies with any rule.
