Movement

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

By model

How each model treated Plan A across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

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.

“For a broader range of compliance frameworks and a focus on decarbonisation, Plan A is a strong alternative.” Mistral Small · ESG and carbon reporting · paraphrase prompt · first choice

“Sweep / Coolset / Plan A / ESG:ONE: These are specifically built for upper-mid-market companies.” Gemini 3.5 Flash · ESG and carbon reporting · scale prompt · first choice

“If you want a single default recommendation, I'd choose Plan A for most mid-sized B2B companies” Perplexity Sonar · ESG and carbon reporting · paraphrase prompt · first choice

“I'd suggest starting with Plan A or Coolset if you're in Europe and need CSRD compliance” MiniMax M2.5 · ESG and carbon reporting · paraphrase 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.

“unproven mid-market carbon tools like Sweep, Plan A, or lower-rated ones” Grok 4.1 Fast · ESG and carbon reporting · negative 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 Plan A. 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 22 of the 23 answers that named Plan A 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 Plan A'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 Plan A, 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 plana.earth 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.
