What is a ChatGPT shopping assistant?

She asks ChatGPT for a rain jacket

Picture someone who keeps getting caught in the drizzle on the walk to work. She opens ChatGPT on her phone and asks for a rain jacket for less than $200.

ChatGPT answers the way a good shop assistant would. It shows her a short row of jackets as cards, each with a photo, a name, and a price, and one of those jackets is yours.

That is what people mean by a ChatGPT shopping assistant. It lives in ChatGPT rather than on your store, and it finds jackets, lines them up, and lets her pick one before she has ever visited a shop. If you sell on Shopify, your products can already be in that row.

She likes the look of your jacket, so she taps it. Your own product page opens, and the photo she just saw in the chat has to be the first thing she sees there too.

How your jacket gets onto that card

So where did ChatGPT get your jacket’s photo and price? From you, mostly. Shopify’s article on Catalog says it starts from what you already keep in the admin: the title, description, photos, category, sizes and colours, price, and stock.

Shopify gathers those details from eligible stores into one product list for these chats, and that list is called Shopify Catalog. When she asked for a jacket, that list is where ChatGPT went looking.

Then ChatGPT does the choosing. The same article says each chat decides which products to show and how to rank them, weighing her request, how good your product details are, availability, price, shipping, and a few other things. Being in the list does not guarantee your jacket makes the row.

So you write the card, and ChatGPT decides whether she sees it.

How did your store get into that list without you doing anything? On 24 March 2026, Shopify said products show up in ChatGPT by default through Agentic Storefronts, the admin setting that shares your products with the chats.

That same post says there are no separate integrations, no apps, and no transaction fees beyond the standard processing rates you already pay on any sale.

Next up is the tap. Shopify’s March post also says ChatGPT opens your store in a browser inside the app, and on a computer it opens your store in a separate tab.

Either way, she is on your real product page now, with your theme and every app you have installed. Shopify’s post on ChatGPT says checkout finishes on your own site, so your prices, your payment methods, and your brand stay as they are.

What you can leave alone, and what the tap opens

This is the useful part, because most of the work is already done. You do not install an app, you do not upload a spreadsheet of your products, and you do not write special descriptions for ChatGPT.

The details you keep for your own store are the details the card is built from.

Shopify’s guide to how this works says it is live for Shopify stores selling to US buyers, whatever country the store is in, and there is no monthly subscription for the channel.

You may have read about a Buy button that takes payment right inside the chat. That is a separate buy button for approved stores, and for ChatGPT on Shopify, the same guide says checkout happens on your own store, with no separate switch to turn on.

What you still have to get right is the jacket, in two places. The first is the admin, because the card reads from it. Shopify’s Catalog article asks for photos of the product itself, not only lifestyle shots, and for price and stock that are kept current.

That second request matters more than it sounds. If the card told her the jacket is in stock at a price, and your page says something else, she has a reason to go back to the chat and tap someone else’s.

The second place is the page the tap opens, and this is where the two endings split.

In the good ending, your product page opens and the jacket photo is the first thing on screen. The price matches the card, her size is there, and she keeps shopping on your store.

In the other ending, a signup popup lands before the photo does, or the first photo is a model on a hillside where the jacket is hard to make out. She came from a card that showed her exactly what she wanted, and now she has to look for it.

I know what you’re thinking. ChatGPT already showed her the jacket, so why does the page matter that much? Because the chat only found it. The sale happens on your page, on her phone, in a small browser, with every app you have installed loading as the page opens.

Check your jacket the way she will see it

OK, so here is the check, in the order you would click it, on one product. Pick the jacket, or whichever product you would most like to see in that row.

1. In the Shopify admin, open Settings, then Sales channels, then Agentic Storefronts, which is where Shopify’s guide says you manage these chats, and make sure ChatGPT is on.

2. Open the jacket in Products and read it the way she would. Does the title say rain jacket, or only a name you made up? Check the price and the stock for each size, and make sure the first photo shows the jacket itself.

3. Open the live product page on your phone, using the address a customer would use rather than the theme editor. Reload it and watch what lands first. The jacket photo should be on screen before any popup or chat bubble.

If the photo is slow to appear even with nothing in front of it, the file may be bigger than her phone needs, and why image optimization still leaves photos slow walks through that one.

That last look is where Whoosh fits. It does not put your jacket in ChatGPT, and it does not choose which jackets ChatGPT shows.

What it does is AI Page Preloading. It learns from real visits which photo shoppers see first on each product page, then tells the browser to fetch that photo early, so the jacket is ready sooner when she lands from the chat.

AI Page Preloading is US$99 a month on the Shopify App Store, with a 7-day free trial.

You can stop when the admin matches the page and the jacket is the first thing she sees. If a popup still gets there first, the next suspect is the app that runs that popup.
