Shopify's Canvas lets merchants build stores by chatting with AI

Shopify launched Canvas on Thursday, an AI-powered site-building tool that lets merchants construct online stores by chatting with the company's Sidekick agent instead of dragging theme blocks or writing code.

What is Canvas?

Canvas is the first Shopify product to wrap the full site-building experience around a chat interface. Merchants type instructions to Sidekick, which edits the store's underlying files while displaying the live result in real time, according to Shopify. The view is not a static mockup. The platform renders the actual code behind each page, so merchants can test full interactivity, animation, and how pages appear across different screen sizes.

The result is a working storefront, not a prototype. Sidekick takes its own screenshots of the site as the AI makes updates, so the agent sees exactly what the merchant sees at any given moment.

How is it different from the old builder?

Shopify's previous no-code tool asked merchants to pick a theme and rearrange modular sections and blocks. Anything deeper — custom layouts, unusual interactions, fine-tuned design — meant editing code or hiring a developer. Canvas removes that gap. Sidekick now touches the theme's structure, logic, and design directly, so the AI agent can handle changes that previously lived outside the no-code path.

How does the AI see what the merchant sees?

Sidekick captures screenshots of the work as it updates, so the agent views the same page the merchant is viewing. That feedback loop lets Sidekick understand layout, spacing, and visual hierarchy before pushing a change. Shopify also simplified the theme architecture itself, so the underlying files are easier for the AI to read and modify without breaking the live store.

Merchants who want hands-on control can still click individual page elements and edit them directly. The chat interface is the default, not the only path.

Where does Sidekick fit in Shopify's existing stack?

Sidekick is not new. Merchants have already used it to write code, build apps, customize themes, and handle one-off edits. Canvas pulls those capabilities into a single product that shows the entire store at once, with the ability to zoom and pan across live files while changes are being made. It is the first time Shopify has bundled those Sidekick functions into a full site-building product.

Who else is competing in this space?

Canvas enters a market already crowded with AI-driven site builders. Wix, Squarespace, Webflow, and Framer all offer AI-assisted site creation, while vibe-coding platforms Lovable and Replit let users build full applications through chat. Shopify's pitch for Canvas is accessibility. The company says the tool could make online selling possible for people who don't have the budget for developers and designers, or the time to learn to code.

What are the limits?

Shopify described Canvas as being in its early days and acknowledged that there are areas where the product will need to expand and improve. The launch positions Sidekick as a central layer across the entire storefront, and the company is betting that simplifying the underlying theme architecture will be enough to make the AI reliable for merchants who previously needed developers.

Why this matters for merchants

For independent sellers, the shift cuts both ways. The conversational interface lowers the technical floor for launching a store, but it also means a third party — the AI agent — is shaping the customer-facing presentation of the business. How much control merchants retain over brand-specific design choices will determine whether Canvas functions as a productivity tool or a constraint as Shopify rolls the product out further.
