Movement

This is the first edition on this tier, so no move can be computed for ThirdProof yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

What the models said for it

Verbatim evidence the judge attached to positive labels.

“For the absolute tightest budget with unlimited vendor checks, ThirdProof is the standout value at ~$399/month.” DeepSeek V4 Flash · TPRM · budget prompt · first choice
“Choose ThirdProof if you want a "flat fee" SaaS that won't get expensive as you add more vendors.” GLM 4.7 FlashX · TPRM · budget prompt · first choice

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.

No model argued against it.

What carried it into the answer

The sites and pages cited by the answers that named ThirdProof. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 6 of the 6 answers that named ThirdProof and are not a share of its labels.

Claim this page

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

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at thirdproof.ai is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
