What's New in the Shopify Winter '26 Update

Shopify has introduced one of the most innovative updates in recent years. Winter ’26 places artificial intelligence at the center of the e-commerce experience, offering tools that automate processes, increase conversions and open new growth opportunities for businesses of all sizes.

It has taken a step forward as one of the most advanced CMS platforms in AI integration, helping online stores simplify processes and benefit from various functionalities, such as having an expert assistant available 24 hours a day, every day of the year. We have also seen progress in the integration with ChatGPT Checkouts and improved transmission of information to the LLMs that interpret product data.

Below, we review the most relevant points of the update and how we can use these functionalities to improve e-commerce stores more simply and efficiently.

Sidekick Pulse

One of the major new features of Winter ’26 is Sidekick Pulse, the evolution of Shopify’s integrated AI assistant. This tool not only answers questions but acts as a true collaborator, capable of executing complex tasks and automating internal processes that previously required time, technical knowledge or manual intervention.

What can Sidekick Pulse do?

• Create discount coupons and personalized promotions.
• Generate and organize product collections automatically.
• Personalize email marketing campaigns adapted to different segments.
• Create customer segments based on behaviors or demographic data.
• Develop internal apps to automate processes (such as inventory control).
• Prepare advanced reports and metrics according to business needs.
• Make design adjustments in the store without needing to touch code.
• Edit images using AI with its own integrated intelligent editor.

It stops being just a generative conversational AI and becomes part of the Shopify ecosystem, able to make modifications across different CMS areas. It even includes an AI-powered image editing system that appears highly effective and similar to the well-known Nano Banana from Gemini.

One of its most interesting capabilities is the ability to analyze and offer strategic recommendations, such as:

• Why are customers abandoning the checkout page?
• How can I improve the SEO of a specific product?
• What actions can increase conversion in a specific category?

In other words, Sidekick Pulse not only executes tasks: it provides insight and data-driven decision-making.

Agentic AI

Another major Shopify innovation is Agentic AI, a system that lets you configure how your brand and products appear in leading AI chat platforms such as ChatGPT, Microsoft Copilot, Perplexity and more in the future.

Following the agreement between OpenAI and Shopify to display products from Shopify-based stores inside ChatGPT Checkout, we now understand how to configure this connection from the admin panel and decide what information we want AI systems to use.

How does it work?

Structured catalog for AI

Shopify allows you to define a standardized product schema with well-organized attributes and enriched data. This enables AI platforms to interpret your product information correctly and present it accurately, contextually and relevantly.

Knowledge Base for centralized brand information

Shopify includes a tool where you can configure key business data, such as:

• Shipping policies
• Returns
• Taxes
• Compliance requirements
• Frequently asked questions

This information is used so that AI systems can respond to customers with accurate, up-to-date and fully aligned information from your store.

A single setup for visibility everywhere

You only need to set up your catalog and knowledge base once. From there, Shopify automatically distributes this information to all compatible AI platforms, with no additional integrations, no APIs and no technical complexity.

A/B Testing and Buyer Behavior

Shopify reinforces its focus on continuous e-commerce optimization with two key tools that allow you to validate decisions before implementing them in your store: Rollouts and Shopify SimGym. Both make it easier to test changes, understand how buyers will react and launch updates with complete confidence.

Rollouts

With Rollouts, you can now schedule theme changes and run A/B tests directly from the Shopify admin panel. This allows you to:

• Test new versions of pages, designs or content.
• Compare performance between two variants before launching changes.
• Schedule gradual releases to minimize risk.

It is a simple and native way to ensure each update truly improves conversions.

Shopify SimGym

The new Shopify SimGym app uses AI agents trained on data from billions of real purchases. Thanks to this, you can:

• Simulate how different types of customers would browse and shop.
• Detect friction points in the buying process.
• Receive practical recommendations before launching updates publicly.

SimGym enables data-backed decisions based on solid predictions, avoiding blind testing and reducing errors before they impact real users.

Shopify Product Network

(Currently available only in the U.S.)

Shopify Product Network is one of the most disruptive features of the update. It allows a store to offer products it does not keep in stock, but that customers are actively looking for, by showing relevant recommendations from other Shopify stores.

This means that if a customer needs a complementary product you do not sell (for example, a helmet to go with a skateboard), they can find it and add it to their cart within your own store, without being redirected elsewhere.

The most important advantage is that even if the product comes from another store, the customer remains your customer. You can continue marketing to them, build long-term relationships and, additionally, earn a commission on the sale.

In practice, Shopify Product Network turns your store into a more complete and competitive ecosystem without requiring investment in new inventory or assuming logistical risks.

Conclusions

The Shopify Winter ’26 update marks a turning point in the evolution of e-commerce. The platform integrates artificial intelligence at every level: from daily store management with Sidekick Pulse, to AI-powered visibility through Agentic AI, advanced optimization tools such as Rollouts and SimGym, and the revolutionary Shopify Product Network that expands product offerings without increasing inventory.

These innovations not only help automate tasks and improve operational efficiency, but also open new sales channels, enhance user experience and generate growth opportunities for any online store, regardless of size.

Shopify is solidifying its position as one of the most advanced CMS platforms in AI integration, enabling e-commerce businesses to evolve faster, with less friction and with data-driven decision-making.
