What the models said for it

Verbatim evidence the judge attached to positive labels.

“Nuclino offers a free version with core features such as unlimited workspaces and up to 50 items” Claude Haiku 4.5 · Knowledge base · budget prompt · alternative

“Nuclino at $6/user/month is the best value” DeepSeek V4 Flash · Knowledge base · budget 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.

“High-Risk Tools to Avoid ... Outline & Nuclino ... Will fail enterprise procurement security requirements” Mistral Small · Knowledge base · negative prompt · hard negative

What carried it into the answer

The sites and pages cited by the answers that named Nuclino. 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 8 of the 47 answers that named Nuclino 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 Nuclino'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 Nuclino, 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 nuclino.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.
