Can you edit what Shopify’s catalog says about your products?

Short answer: no. Shopify’s help page for the catalog says you cannot directly edit Shopify Catalog itself, and we haven’t found any setting in the admin or the API that lets a merchant rewrite the summary it holds for a product. Nobody outside Shopify can edit it, and that includes us (our FAQ says the same).

That doesn’t leave you with nothing to do. The catalog’s version of your product is built from your listing, so the work moves one step upstream. This guide covers which inputs count, how much to expect from each, and what to do when your copy is right and the catalog still isn’t.

Why there’s no edit button

Shopify describes the catalog as “a structured source of product information gathered from eligible products that are sold by stores on Shopify” (Shopify Help Center). It’s a derived record, not a second product page you maintain. Part of it is also written by Shopify’s models: the developer docs mark the description, top features, tech specs and selling points as Inferred, and say they “might vary in accuracy depending on available product data” (Global Catalog docs). We go through each of those fields in What Shopify’s AI adds to your listings.

If you haven’t read how the catalog works at all, What is Shopify Catalog? is the place to start.

What you can change

Three levers exist. None of them is a direct edit, and Shopify is careful not to promise a result from any of them.

Your own listing

This is the input everything else is built from. Shopify’s guidance is to make sure you’re “using clear, accurate, and detailed descriptions,” and it lists the fields AI platforms consider: title, description, images, product type, vendor, collections, tags, barcode and variants with option names (Optimizing your products for AI platforms).

Two habits help most. Put any fact that matters in the description in plain words, not only in an image or a collapsed tab. And make sure the listing agrees with itself, because a summary built from a description that says “all ages” and an ingredients tab that says “not under 6 months” has to pick one.

Catalog Mapping

If your real product data lives somewhere other than the default fields, Shopify lets you point the catalog at it. Its page says mapping “lets you manage the AI discovery of your products for Shopify agentic storefronts” (Mapping your product data sources). The same page says changes are processed with a delay. Shopify also notes many stores might not need to make any changes, and that mapping is most helpful for stores with custom data structures. Our walkthrough is in Shopify metafields for AI shopping.

Which channels can read it

You can’t opt out of the catalog itself. Shopify says so directly. You can stop individual AI channels from reading your products, and our agentic storefronts guide covers the settings. That changes who sees the summary. It doesn’t change the summary.

What none of it guarantees

Shopify says mapping “doesn’t guarantee product placement, ranking, or exact wording in AI search results.” Being in the catalog doesn’t guarantee a product will appear in a specific AI answer either.

So an accurate edit to your listing makes a wrong summary less likely. It doesn’t force a particular sentence. Shopify’s help pages don’t say how long a listing change takes to reach the catalog, and we haven’t found a published figure. Treat any promise of a specific turnaround with suspicion, and check again after a few days instead of an hour.

A fix that has a fair chance of working

Suppose the catalog calls a product “fragrance-free” and your ingredient list includes essential oils. Here’s a sensible order:

1. Read what the catalog actually says. Guessing from an AI answer is unreliable, because channels can reword what they receive.
2. Compare it with your description, tags and product details. Decide whether the claim is wrong, or simply something you never said.
3. If your copy is unclear, fix it and state the fact early and plainly.
4. If your copy is already clear, leave it alone. There’s nothing to fix on your side, and rewriting accurate copy won’t help.
5. Check the catalog again later, and keep a dated copy of both versions.

Step 4 matters. Some claims come from Shopify’s summary alone, and editing your page to “correct” them can make your own listing worse. The steps in AI getting your product wrong? go further on tracing a claim to its source, and Fixing a finding explains what a fix note can and can’t do.

When to contact Shopify

If your copy is clear and the catalog still says something else, contact Shopify Support and show them both versions. We haven’t found a published process for correcting an inferred claim, so expect a support conversation rather than a form. Be specific about which product, which field and which words, and include the dates you checked.

It’s worth knowing how common this is before you assume your store is the exception. On Sep 24, 2026 we read the catalog’s version of 192 top-ranked products and checked 3,546 claims against each brand’s own copy. 89% of the products had at least one claim the brand never made (how we checked). That was one day and the top results only, so it’s not a rate for your store. The full write-up has the details.

Common questions

Can I edit the catalog through the Shopify API?

We haven’t found an endpoint that lets a merchant write the catalog’s inferred fields. Shopify’s catalog API is documented for agents that search and read it. If Shopify adds a way to write, its docs will say so.

If I fix my description, will the catalog update?

It can, and Shopify’s help pages say the catalog is built from your product data. It isn’t instant, and the exact wording isn’t guaranteed. Recheck after a few days.

Is there a way to see the catalog’s version next to mine?

Shopify’s admin search preview under Sales channels > Agentic shows how products rank for a query. It doesn’t line up the catalog’s claims against your copy. Hearsay does. The free scan needs no install, reads 5 of your products, and flags each claim you never made, and the app emails you when a claim changes. We can’t edit Shopify’s summary either. We show you what it says and where it differs from you.
