Movement

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

By model

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“I'd choose Persefoni because it has a free single-user tier and is repeatedly positioned as the cheapest starting point” Perplexity Sonar · ESG and carbon reporting · budget prompt · first choice

“### 1. Persefoni Pro (Free) ... Start with Persefoni's free tier” MiniMax M2.5 · ESG and carbon reporting · budget prompt · first choice

“Top Recommendation: Persefoni ... robust free tier” Qwen 3.7 Flash · ESG and carbon reporting · budget prompt · first choice

“If you are a financial institution managing the emissions of your investments, choose Persefoni.” Gemini 3.5 Flash · ESG and carbon reporting · 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.

“Enterprise-grade platforms (like *Workiva*, *IBM Envizi*, or *Persefoni*) are usually overkill” Gemini 3.5 Flash · ESG and carbon reporting · scale prompt · soft negative

A head-to-head page exists where both products are in a category's top three. The other rows are the same fact without a page behind them, so they link to the product instead.

What carried it into the answer

The sites and pages cited by the answers that named Persefoni. 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 65 of the 75 answers that named Persefoni and are not a share of its labels.

Is this your product?

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 Persefoni'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 Persefoni, 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 persefoni.com 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.
