Shopify Sidekick is the AI agent built into your Shopify admin. Unlike a general chatbot that can't see your store, Sidekick reads your store data and takes actions for you, from writing product descriptions to pulling a weekly sales summary. Since October 1, 2026 it can also redesign your theme with you in Canvas, a new visual workspace that Shopify is rolling out in early access.
That last part is the news, and it changes what you can realistically hand off. Until now, a custom store meant learning code, paying a developer or fighting the theme settings panel. Canvas puts every page of your store side by side, and you tell Sidekick what you want changed. Here's what that looks like in practice, what to try first and where it still falls short.
What Sidekick does today
You open Sidekick from your Shopify admin by clicking the purple glasses icon. There's nothing to set up. You type a request in plain language and Sidekick works with your actual store data, inside the permissions your account already has.
Shopify's own Sidekick page lists the everyday jobs it suggests as starting prompts:
- Write product descriptions for search
- Analyze your pricing and suggest changes
- Give you a weekly performance summary
- Set up discount codes and offers
- Flag products before they run out of stock
- Organize products into collections
- Audit your shipping settings
Two practical details matter for a small team. Sidekick is included with your Shopify plan, though Shopify says features and usage limits vary by plan. And every staff member can use it, but only with the data and features their admin permissions already allow. A part time helper with limited access gets a limited Sidekick.
What changed on October 1: Canvas
Shopify announced Canvas on October 1, 2026 as "a new design surface where merchants build with Sidekick." Think of it as a big table where every page of your store is laid out at once. You can pan across the whole store to see how it feels, then zoom into one page to fix a detail.
You can still click an element and change it yourself. The new option is to describe the change in the chat and let Sidekick build it. Its edits appear in Canvas as they happen, and you're looking at a working version of your real store, not a static mockup. You can preview pages with real products, different collections and different screen sizes.
Under the hood, Sidekick now works directly on your theme's files. A theme is the set of templates and code that controls how your store looks. As it works, Sidekick checks that its code is valid and takes screenshots to see how its changes actually landed, then fixes what looks wrong before handing the result back to you. Shopify says Sidekick made more than 25 million theme edits in the first half of 2026, before Canvas existed. That's Shopify's figure, but it tells you this isn't a brand new experiment.
Four jobs you can hand Sidekick this week
If your store has Canvas, these are realistic first projects. Each one starts the same way: open Canvas from the Themes page in your admin and work on a copy of your theme, not the live one.
- A homepage refresh. Describe the feeling you want ("calmer, more white space, our bestsellers higher up") and let Sidekick propose a direction. Review it on desktop and phone sizes before you keep anything.
- A new collection page. Ask for a page that tells the story behind a product line, such as a holiday gift guide. Point Sidekick at the products you want featured and say what the shopper should do next.
- A custom section. This is where Canvas helps most. If the block you need isn't in your theme's settings, ask Sidekick to build it, say a size chart or a "how it's made" strip. Shopify's help pages say you can't add a new block by hand in Canvas, so asking Sidekick is the way.
- A store wide restyle. Fonts, colors and spacing across every page at once. Because Canvas shows the whole store together, you can see whether the new look holds up on the product page and the cart, not just the homepage.
Treat each one like briefing a freelancer. Say what you want, what you don't want and how you'll judge it. Then look at the result like a customer would before you publish anything.
Where Canvas stops, in Shopify's own words
Shopify is unusually direct about this. "We're early here and Canvas is not replacing the existing editor yet," said Ben Sehl, Shopify's Director of Product, in the launch post. "Things will change quickly, and there are gaps we still need to close."
The Canvas requirements page in Shopify's Help Center spells out the gaps as of October 7, 2026:
- Early access only. Canvas is available only to certain stores while it rolls out.
- Desktop only. You can't use it from your phone.
- Plan and theme limits. It needs a plan that includes theme customization, and it works only with themes made by Shopify or custom themes. Third party themes aren't supported.
- Permissions. Staff need the theme "Edit code" permission to open it.
- No more theme updates. A theme you edit in Canvas stops receiving updates from its developer, and you can't download its files.
- Missing pieces. You can't add app blocks or app embeds, customize a theme for different markets, or translate theme content inside Canvas.
That theme updates point is the one to think about before you start. If you rely on your theme developer's fixes, editing in Canvas means you own that theme from then on.
Should you try it?
If you run a small store and you're the one who does everything, Sidekick is already worth using for the admin chores above. It's included in your plan and it sees your real data, which a general chatbot can't.
For Canvas, the honest answer is: experiment, but on a copy. Use it to explore directions you'd never have paid a designer to mock up, then keep what works. Don't make it the only way your store gets built while Shopify itself calls it early.
The bigger skill here isn't Shopify specific. It's learning to brief an AI agent clearly and check its work before it reaches customers. That's the same habit you need with Meta's Muse for small business or ChatGPT Sites, and you'll find more tools like these in our AI tools hub. If you want a structured way to build that habit around your own work, with no coding required, a short program can get you there faster than trial and error.
