What the models said for it

Verbatim evidence the judge attached to positive labels.

“BigMarker operates in the browser and offers completely white-labeled, custom-branded experiences” Gemini 3.1 Pro · Webinars · comparative prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“carries a steep price tag and a steeper learning curve, making it expensive for small businesses” Claude Opus 5 · Webinars · budget prompt · hard negative

Claim this page

Claiming is free and changes nothing in the data. A claimed page gets a verified contact who is told when each edition publishes; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as BigMarker, applied by version and listed in the change log; and a logo and one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or quadrants, any preview, or any say over which quotes appear. Sponsorship is separate: a sponsor funds categories or buyer dimensions and is named on what it funded, and the rules are the same for every sponsor.
