On October 28, Shopify gave AI agents a page on your store that says what you promise customers. It is called the Shopify knowledge base, and you can read it in about ten minutes. Most merchants have not.

Your return window, your shipping destinations, your warranty. All of it sits in one admin page, and ChatGPT, Gemini, Copilot and Muse can quote it. If a fact on that page is wrong, an AI agent repeats it to a buyer with total confidence.

Here is what shipped, what to check, and where it gets fiddly.

What Shopify Shipped in the Fall '26 Edition

Shopify's Fall '26 Edition landed on October 28 with the usual long list. Two items matter if you sell through AI channels.

First, a view that shows whether your store is eligible for Shopify Catalog, the product data AI agents search, and what to change if it is not. Second, a knowledge base for the non-product facts agents need: policies, FAQs, contact details. Shopify's merchant summary says agents "only get facts the merchant has published."

Both live in the same place: Sales channels, then Agentic, in your Shopify admin.

The knowledge base replaces Shopify's older Knowledge Base app, which can no longer be installed. We covered the checkout side of this wave in our post on Shopify WebMCP checkout and the Meta side in Muse buying from your store. This post is the part both of them skip: what the agent says before it buys.

The Knowledge Base Is a Public Page Written for Machines

Read Shopify's help doc once, slowly. Three lines matter.

Published content is public. Shopify says it is available through the Storefront MCP, including to AI channels such as Shop and third-party platforms. Treat every fact as if it were printed on your homepage.

Shopify drafts it for you. It scans your public storefront and your admin data and proposes facts. It "never changes knowledge base content on your behalf," so nothing scanned goes live until you approve it.

The scan is not a guarantee. Shopify's own doc says scans do not always catch storefront changes and suggestions can take time to show up. If a fact matters, add or edit it directly.

For buyers, checkout is important, but not nearly as important as discovery.

— Vanessa Lee, VP of Product, Shopify

Lee said that in Shopify's Fall '26 interview. It is the right frame. The knowledge base is the discovery layer for the questions a product listing cannot answer: Can I return this? Do you ship to Austria? Is there a warranty?

Eight Categories, and Where Stores Get Them Wrong

The knowledge base groups facts into categories: about the store, brand and identity, company policies, contact, gift services and payment, returns and warranty, fulfillment, and additional facts you write yourself. Additional facts come in three types: paragraph, yes/no, and tags.

Here is where we would look first.

Returns and warranty. The return window and refund information. This is the fact with the highest cost of being wrong. A store that changed from 30 days to 14 for the holidays has two numbers floating around: the policy page and an old FAQ. A scan can pick up the stale one.

Company policies. Shopify flags missing policies. Fix the flag, but also open the actual policy pages and confirm they say what you think they say.

Fulfillment. International shipping and pickup. If you cut a country last quarter, check that the agent does not still promise it.

Contact. Address, email, phone, social profiles. Boring, and the one most likely to be six months out of date.

Additional facts. This is where you win. Write the answers to the five questions your support inbox gets every week. Gift wrapping, order cut-off dates, whether you sell second-hand items, what a material is made of. Yes/no and tag facts cost nothing and give an agent something precise to quote.

Catalog Eligibility Is a Review You Can Fail

Knowledge base facts are only half the picture. Product discovery runs through Shopify Catalog, and Shopify's requirements doc is blunt about what disqualifies you.

Per that doc, each product needs a title, at least one image, a price above zero, and a publication on the online store, Hydrogen or Headless channel. Products cannot be Unlisted or hidden from search engines. The store cannot be password-protected.

Then the exclusions. Shopify says products cannot fall into excluded categories, and the list includes alcohol, tobacco and vaping, weapons, prescription and medical products, adult content, money-related products, services, event tickets, live animals, and uncategorized products. Shopify classifies products from their product information, which may differ from the category you set in the admin.

Two details are easy to miss:

• Services are excluded. If you sell bookings, consultations or classes through Shopify, those products will not reach agents through Catalog.
• Eligibility is reviewed over time. Shopify says you can lose it if requirements stop being met. The doc lists operating history too: real sales to real customers, prompt and accurate fulfillment, low chargebacks, and invoices paid on time.

The admin now shows your status and the reason if you are ineligible. That is the first check to run, because everything else on this page assumes you are in.

A Wrong Fact Is a Promise

Here is the opinion we will stand behind. In an AI chat, a policy answer is not a search result. It reads like a statement from you, delivered at the moment of purchase, and a buyer will screenshot it.

If an agent says "returns accepted within 60 days" and your policy says 30, you now have a customer service problem and, depending on where you sell, possibly a consumer-law one. We are not lawyers and this is not legal advice. The practical point is simpler: the cheapest moment to fix a wrong fact is before an agent says it.

This is the same lesson as our audit of our own two Shopify stores. Defaults get you to legible. The gaps are where you lose, and you cannot see them from the storefront. Machines read the page you never look at.

It also connects to a broader rule we hold for any AI that talks to customers: ground it in facts you control, and keep those facts in one place. We wrote the long version in AI customer support that doesn't invent answers. The knowledge base is Shopify's version of that grounding layer, and the grounding is only as good as what you put in it.

The 30-Minute Audit

You can do this yourself today.

1. Check eligibility. Open Sales channels, then Agentic. Read the Catalog status. If you are ineligible, read the stated reason before anything else.
2. Open the knowledge base and read every published fact. Not the suggestions. The live facts. Toggle anything you cannot verify to unpublished (you can do this per fact, per category, or for everything).
3. Compare against the source. Open your returns, shipping and privacy policy pages next to the knowledge base. Match the numbers: days, countries, costs, exclusions.
4. Review suggested updates. Approve what is right. Reject what is wrong with the thumbs-down so Shopify has the reason.
5. Add five facts yourself. Pull them from your support inbox. Use yes/no and tags where you can.
6. Check your channels. In the same Agentic area you choose which AI channels you sell on. ChatGPT is discovery-focused, with checkout on your online store. Google AI Mode, Gemini, Copilot and Meta surfaces such as Muse can offer direct checkout if you activate it.
7. Put a date on it. Reopen this page every time a policy changes, and at least quarterly.

If the Knowledge Base app was installed on your store with more than 1,000 facts, Shopify says you must move the extra facts and overrides manually before the app is deprecated on January 15, 2027. Apps with 1,000 or fewer facts transfer automatically. Custom storefronts and stores on the Agentic plan can only add additional facts.

When Doing It Yourself Stops Working

For one store with one return policy, the audit above is the whole job. Do it and move on. We would tell you that on a sales call, too.

It stops being a 30-minute job in three situations.

The same facts live in four places. The store, the helpdesk macros, the WhatsApp or chat bot, the transactional emails. Someone changes the return window in one. Three are now wrong, and one of them is an AI agent.

You run several stores or markets. Different windows, different shipping lists, different languages. Drift is guaranteed unless something compares them.

Nobody owns it. The knowledge base is a living page. A quarterly reminder survives about two quarters.

That is automation work, not design work. A single policy source, a workflow that diffs it against the live knowledge base and your helpdesk, and an alert when they disagree. It is a small n8n build, and it is precisely the kind of thing we set up and run for stores through our automation service. Bunny Honey Club sells this, so weigh that accordingly: if you have one store and one policy, do not hire anyone.
