Movement

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

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Enjoy high‑quality, inspirational lessons from world‑class experts | MasterClass” MiniMax M2.5 · Online course libraries · comparative prompt · alternative

“Learning from famous experts | MasterClass” Kimi K2 · Online course libraries · 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.

“MasterClass - not recommended for certain goals, such as employer-recognized credentials or data science/ML career.” Llama 4 Maverick · Skills intelligence · negative prompt · soft negative

“slammed for auto-renewal traps, hard cancellations, and refund disputes—not the courses themselves” Grok 4.1 Fast · Learning experience plat · negative prompt · soft negative

“auto-renewal charges without warning, hard-to-find cancellation, and refund disputes” DeepSeek V4 Flash · Skills intelligence · negative prompt · soft negative

“being more cautious with platforms like Skillshare and MasterClass” Perplexity Sonar · Skills intelligence · negative prompt · soft negative

A head-to-head page exists where both products are among a category's top eight. 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 MasterClass. 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 13 of the 19 answers that named MasterClass and are not a share of its labels.

Follow MasterClass

An email the morning each edition publishes: where this product moved, where it held, and by how much against the noise floor. One address, confirmed by a click; a stop link in every email.

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 MasterClass'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 MasterClass, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

With a new claim: the vendor brief

A new claim receives the current edition's vendor brief for MasterClass by email, built from the raw record of the edition. It shows:

where MasterClass is named, by buyer and by framing, and which cells hold its first choices;
the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
its vocabulary against the segment leader's, and the pages the models cited;
who was chosen in the answers that did not name MasterClass, and every reason the record gives;
a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
one page of published figures cleared to show a buyer.

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 the vendor's own domain 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.
