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.

“their refer-a-friend features are often basic and rigid... advanced features like API access and custom integrations are often gated behind incredibly expensive tiers” Gemini 3.5 Flash · Referrals · negative prompt · soft negative
“Billing disputes (charges post-cancel, free plan limits eroding, overcharges on order counts); support delays on refunds” Grok 4.1 Fast · Loyalty · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Smile.io. 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 20 of the 115 answers that named Smile.io 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 Smile.io'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 Smile.io, 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 smile.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.
