Only what the vendor documents, dated October 8, 2026, then what our weekly checks see AI shopping actually read, and what a business does about it.
OpenAI is the vendor that documents shopping most plainly. Its help center says ChatGPT's product results "are selected independently by ChatGPT and are not ads, nor influenced by any OpenAI partnerships", that "ads are separate from product results", that a product appears when ChatGPT judges it relevant to the buyer's intent using the query and context such as memory, that merchants on Shopify "are already connected through Shopify Catalog" while other merchants "can apply for direct feed access", and that merchants listed for a product are ordered by "availability, price, quality, and whether they make or primarily sell the item".
Google says its AI features need nothing beyond ordinary Search eligibility and uses a query fan-out to assemble a response; Perplexity describes answers built from "authoritative sources" with numbered citations; neither documents a separate product-card mechanism in the pages we read. Where a vendor's statement is not quoted here, we have not seen one.

A product answer has two layers and they come from different places. The text names brands and products and is written from roundups, retailer pages and brands' own sites, the way every other answer is. The product cards beside it come from catalog feeds and retailer listings, and in our checks they are labelled as such in the links (a Shopify catalog parameter on a brand's own card, a retailer's domain on another). A store can be named in the text and absent from the cards, or the reverse, and the fix for each layer is different: pages and listings for the text, the feed and the product data for the cards.
Rows from scans and checks run in September and October 2026, with the companies unnamed where they have not agreed to be named.
| Category | What happened |
|---|---|
| Wallets | Asked for the best slim leather wallets, ChatGPT named eight products from five brands with prices and showed a shopping carousel that sold them through two retailers and a brand's own store; the client, a Shopify store with 32,000 reviews, was in neither the text nor the cards. |
| MagSafe wallets | Asked for the best MagSafe leather wallet, ChatGPT built the answer from a magazine's guide and a design blog and showed cards from a retailer, a department store and two brands' own stores. Gemini, asked the same question, searched for the client by name and named its product fourth. |
| Full-grain brands | Asked which brands' leather develops a patina, ChatGPT's cards carried two brands' own Shopify catalog entries and two products sold through a department store; the client's Shopify catalog appeared in none of the scan's carousels. |
| Supplements | Asked for the best hair serums, ChatGPT's answer carried product cards from two beauty retailers and the brands' own Shopify catalogs; the client sold through two other retailers and not those, and appeared in neither the text nor the cards. |
For a store, the weekly check archives the product cards as well as the text, so the dashboard shows both layers. Month one starts with the feed: whether the catalog is in the feeds the cards are built from and whether price, availability and maker are right on the product pages. Then the text layer: the comparison and category pages the roundups are writing for your rivals, the facts page the brand answer keeps asking for (where it is made, the warranty), and the inclusion requests to the buying guides the answers read.
OpenAI says product results "are not ads, nor influenced by any OpenAI partnerships" and that ads are separate from product results. What a merchant controls is whether its catalog reaches the feed and whether the product data is right.
OpenAI says Shopify merchants "are already connected through Shopify Catalog"; whether a given store's catalog is syndicated is a setting in the store's own admin, and it is the first thing we ask you to check. Other merchants apply for direct feed access.
Because the two layers come from different sources: the text from the pages the assistant read, the cards from catalog feeds and retailer listings. Being named is the pages' work; being carded is the feed's.
Or start smaller: the AI Page Check runs one page through all four assistants for $2.99.
