Central surfaces source-backed limitations on the PDP, in widgets, in FAQ, and in AI-readable data. Wrong-fit buyers stop checking out before they regret it — surprise returns and 1-star "didn't expect this" reviews don't get a chance to happen.
Every catalog has the same hidden record: 1-star reviews, return reason codes, support tickets, Q&A threads. They all say the same thing — buyers didn't know what they were getting.
Central reads them, deduplicates the signal, and maps each surprise to a verifiable product fact. The result is a queue of negative claim candidates — each one routed to auto-publish, merchant decides, or held.
The same Smart Negatives ship to every place a buyer or agent makes a decision — the PDP, the product widget, and the structured data layer for AI shopping surfaces.

Smart Negatives aren't a generic disclaimer template. They're derived from the verified record for each product — combined with that product's real review themes, return reasons, and Q&A.
The same pipeline finds the right "not for" signal in cookware, fashion, electronics, beauty, baby, and wine. The signal changes; the rigor doesn't.
Medical, legal, dietary, safety, and regulatory claims don't get to ship on confidence alone. Every candidate runs the same trust ladder used across Central — but sensitive categories cross a second floor before they're allowed to publish.
How a claim crosses the second floor.
The promise: Smart Negatives only ship when the record can defend them. Sensitive claims never reach a buyer without a merchant decision or a real authority on file.
The same Smeg TSF01 product page — before, then after. The Smart Negatives don't change what the product is; they change which buyer clicks Add to cart.
No. A Smart Negative is buyer-fit guidance, not a disclaimer. The goal is to help the right buyer choose with fewer surprises. "2 slots only · not 4-slice" lets a buyer who wanted 4-slice skip the wrong product — and lets the buyer who wants a 2-slice toaster feel confident they got it right.
Reviews, return reason codes, support tickets, PDP Q&A threads, and the verified product record itself. Central deduplicates the raw signal and maps each surprise to a specific product fact. Enrichment Engine provides the underlying verified record; Smart Negatives are a layer on top.
A second confidence floor applies. Safety claims need 2+ authoritative sources. Medical claims never publish without an authority on file. Regulatory categories (EU 1169 sulphites, INCI fragrance, ISOFIX compatibility) auto-publish because they're required by law. Every other sensitive claim routes to a merchant review queue before it can reach a buyer.
Yes. Merchant decisions sit above the auto-publish ladder. A merchant can suppress a candidate, edit its wording, or escalate one that Central didn't auto-publish. Every decision is logged in the audit trail so re-enrichment doesn't quietly overwrite human calls.
All of them, from the same canonical record. PDP "What to know" callouts, FAQ entries, the Product Widget "Before you buy" panel, structured data as schema:negativeNotes, and the LLM data layer as x-central.smartNegatives for AI shopping agents.
Yes — that's the whole point. AI shopping surfaces (ChatGPT shopping, Perplexity, Google AI Overviews, voice assistants) read structured product data. Smart Negatives are exposed via JSON-LD and the x-central metadata block, so an agent recommending a product to a buyer can answer "is this a 4-slice toaster?" with the truth — and skip the product when it doesn't fit.
