Standing by category

Every category where a model named Prelude for a mid-market B2B company. Share is first choices across the direct, paraphrase, budget and scale prompts; rank is within every product named in that category.

Movement

This is the first edition on this tier, so no move can be computed for Prelude 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 Prelude across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Choose Prelude or another recruiting-native platform if your process is interview-heavy” GPT-5.4 mini · Interview scheduling · comparative prompt · alternative

“Best for: Recruiting-specific candidate experience” Mistral Small · Interview scheduling · 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.

No model argued against it.

Named alongside

The products named in the same answers as Prelude, over the 11 answers that named it. Took the first choice instead counts the answers where the other product was the first choice and Prelude was named but was not.

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 Prelude. 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 10 of the 11 answers that named Prelude 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 Prelude'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 Prelude, 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 prelude.io 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.
