AI for Shopify: what free Sidekick does, the 6 chat apps that connect, and the 4 outside AI chats that sell

What can AI do for a Shopify store, and which tool does each job?

Shopify's own AI covers all seven jobs below at no extra cost on any plan, as of October 2026. An outside chat app earns its place only in the cases in the third column. We built the table from Shopify's help center on 12 October 2026:

Selling in AI chats is the newest row, and the one moving fastest. Harley Finkelstein, Shopify's president, said on the 5 August 2026 earnings call that AI-driven traffic and orders to Shopify stores had tripled in a year. He added that 75% of AI-attributed purchases in the quarter came from outside Shopify's top 100 product categories (Retail TouchPoints, 5 August 2026). And half of AI-referred sessions land straight on a product page, 2.5 times the rate for traditional search, which puts search at about 20% (our division: 50 over 2.5).

So the product page is now the landing page. A shopper who asks an AI chat for navy running shorts (Shopify's own example) can skip your home page and your collections. That's why the description row matters more than it did a year ago. A model that invents a fabric or a size is writing the first page a buyer sees, and the prompts further down are built to stop it.

Does Shopify have AI built in, and what does it cost?

Yes. Sidekick, Shopify's AI assistant, is included on all four plans at no extra charge, from Basic at $39 a month ($29 a month billed yearly) to Plus from $2,300 a month, on Shopify's pricing page read 12 October 2026. The same page lists "Millions of tokens" as an AI feature of every plan, with no exact number. Merchants had nearly 34 million Sidekick conversations in the second quarter of 2026, and the number of merchants using it daily rose 3.6 times in a year, Finkelstein said on the same call.

Sidekick lives in the admin and reads the page you're on. It drafts products, discounts and collections, writes the query behind a custom report, builds Shopify Flow workflows and makes images from a prompt. It asks before it applies anything. Its limits matter as much as its skills, and Shopify's Sidekick page states the first one plainly: "Sidekick can't talk to your customers or handle customer support conversations on your behalf." Here's what each of Shopify's AI tools costs and where it stops, as of October 2026:

Customer chat goes to the Inbox agent. It answers from your catalog, store policies and Knowledge Base, and it hands the chat to your staff when it hits a limit. One naming note: Shopify Magic, the name Shopify used for its earlier AI writing tools, no longer heads its own help page. The page at the old shopify-magic address now says that when you click the generate icon, "Sidekick writes text" for product descriptions, blog posts, pages and emails.

Can ChatGPT or Claude manage a Shopify store?

Yes. As of October 2026 Shopify's help center lists six chat apps that connect to a store through Shopify's own plugin or connector. Five of the six connector pages say there's no extra Shopify fee, and you pay the chat app's own plan. The Perplexity page doesn't mention a fee at all. What each one can do differs:

Shopify puts the same fences around all six. A connected tool can edit a theme that isn't published, but not your live theme, and it can't change your plan, payments, taxes or domains. Write access doesn't lift the money rule: "A connected AI tool can't issue refunds, cancel or capture orders, mark orders as paid, process returns, or create and adjust gift cards." Changes run one item at a time, so a big batch can stop partway. Status changes go in batches of up to 50 products, and an order list shows up to 50 orders.

Two habits follow. First, duplicate your theme, let Claude or ChatGPT edit the copy, and publish it yourself after a preview. Our AI for coding guide covers how to check code a model wrote. Second, read the privacy line before you connect. Once you approve access, Shopify's considerations page says the data "is no longer processed by Shopify", and its terms make you responsible for your GDPR and CCPA duties to customers. Names, emails and addresses are the part to think about first, and our what never to paste into AI page has the rest.

How do Shopify products get sold inside ChatGPT, Gemini and Copilot?

Automatically, for eligible stores. Shopify's agentic storefronts feed your products to AI channels through Shopify Catalog, the feature is on by default, and no channel adds a fee beyond normal payment processing. ChatGPT is the odd one out. Shopify calls it "a discovery-focused referrer platform", so the buyer pays on your own checkout, while three other channels can take the payment inside the chat. Here's each one, from Shopify's channel pages read 12 October 2026:

Three product types can't be bought in any of those in-chat checkouts: subscriptions, bundles and customizable products. Products sold only to wholesale buyers stay out of AI channels whenever Shopify can spot them. Shopify also asks you to put any legal disclosure in the first 6,000 characters of a product description, which is where a long AI-written description tends to bury it. Shopify's own Shop app runs an AI shopping agent on the same catalog. It's the one channel you can't switch off in the Agentic settings.

Every Shopify store also serves /agents.md and /llms.txt to AI agents on its own, with no app needed. To leave a channel, go to Sales channels > Agentic, turn off Allow Shopify to manage for me, then switch off that channel's Shopify Catalog access. That alone doesn't hide a product. AI tools can still find it by crawling the web, and Shopify says the Unlisted status is how you hide it fully (it hides the product from Google too). Sellers whose store runs elsewhere can use the Agentic plan, which costs $0 a month and charges card rates from 2.9% + 30¢ only when you make a sale.

Which AI prompts work best for Shopify product pages?

The prompts that work carry Shopify's field limits inside them, because no chat app knows those limits unless you say so. These are the ones that matter, from Shopify's help center on 12 October 2026:

The product description. It works in Sidekick's generate box or in any chat app:

```

Write a 120-word product description for [product name]. Specs: [materials, size, weight, care, what is in the box]. Who buys it and why: [buyer and job]. Use only these specs. If a buyer would expect a detail I did not give, write [NEEDED: detail] instead of guessing. No certifications, awards, health claims or "customers love it". Put this legal or safety text in the first paragraph: [text, or none].

```

The SEO title and meta description, one product at a time:

```

From the product description below, write 3 SEO page titles of 60 characters or fewer and 3 meta descriptions of 150 to 160 characters for a Shopify product page. Put the product type in the first four words. Show the character count after each one. No prices, no "sale", no keyword lists. Description: [paste]

```

The alt text. Attach the photo first, then send:

```

Write alt text for this product photo in 125 characters or fewer: what is visible, the color and material, and the scale if a hand or another object shows it. No keyword lists. Do not start with "image of".

```

Check the counts yourself. Models read text in tokens, not letters, and can miss a limit by a few characters. For sales questions, use Sidekick, where the data already is: Shopify's own example prompt is "Show me the total sales for Canadian customers over the past 60 days." A chat app outside Shopify has no numbers to read unless you connect it or paste them. The ecommerce prompts pack has 20 more, from an abandoned cart email to a reorder plan. If you also sell on Etsy, AI for Etsy sellers has that marketplace's title and tag rules, which differ from Shopify's.

Do Shopify sellers need to pay for a separate AI tool?

Not to start. Sidekick, the Inbox agent, the Tinker app and agentic storefronts cost nothing on top of a Shopify plan. Paying makes sense when you want to run the store from a chat app you already use, or when most of your writing happens outside the admin: ad copy, supplier emails, a wholesale pitch. The "best Shopify AI apps" lists are mostly App Store apps like Klaviyo, Gorgias and Tidio, which you install from the Shopify App Store. Prices below come from each vendor's US page or App Store listing, read in October 2026:

This page is published by Whizi, which sells the last row. Starter runs ChatGPT Luna, Claude Haiku and Whizi AI on one login. A Project can pin up to 10 files of 10 MB each, CSV included, so the product CSV you export from Shopify rides along in every chat. Text from one pinned file is capped at 32,000 characters, so a big catalog gets split. Where Whizi loses: it has no Shopify connector, so it can't read an order or save a product, and Sidekick does both for free. Claude Sonnet and side by side model chats start on Pro at $29.99 a month.
