There’s a quiet revolution happening in e-commerce, and it’s not happening in social shopping, checkout UX, or last-mile delivery. It’s about how people find products in the first place. As search behavior evolves, platforms like ChatGPT are moving from passive tools to active shopping companions. What’s powering that leap? Structured product feeds.
ChatGPT has started ingesting real-time product data directly from platforms like Shopify, turning natural language prompts into instant, intelligent product discovery experiences. This shift doesn’t change how people shop, it redefines the entire e-commerce funnel. And it signals a bigger evolution: the rise of ChatGPT product search as a primary mode of discovery.
Traditional search has always been keyword-first. You enter a few terms into Google or Amazon like “black running shoes men size 11,” and the system tries to match those words with listings. But people don’t think in keywords. They think in messy, emotional, context-rich language. “I need a new pair of lightweight running shoes for a half marathon. Nothing too bulky.”
This is where ChatGPT and large language models (LLMs) shine. These tools understand nuance. They don’t just match phrases, they interpret intent. But until now, they’ve had a massive limitation: access to live, structured, commerce-ready product data.
OpenAI’s new approach to ChatGPT product search changes that. With direct integrations into platforms like Shopify’s Catalog API, ChatGPT can now access machine-readable product feeds in real time. That means it doesn’t have to guess what’s available, in stock, or relevant. It knows.
A product feed is essentially a structured database of every item a brand sells, formatted in a way machines can understand. Each feed contains fields like product name, description, price, availability, image links, variants, categories, and attributes. These aren’t just helpful for search, they’re critical.
When ChatGPT queries a product feed, it isn’t just scanning static content. It’s evaluating your inventory in the context of a conversation. That feed is what allows ChatGPT to say, “Here are three men’s running shoes under $150, all under 10 ounces, with positive reviews for long-distance support.”
And because these feeds are updated in real time, they reflect dynamic factors like pricing changes, stock levels, and promotions. This is a game-changer compared to traditional search engines, which often rely on scraped data or delayed indexing. If you're a brand running a 48-hour flash sale, that distinction is everything.
The shift really came with Shopify’s release of its new Catalog API. For the first time, developers (including AI agents like ChatGPT), can access a unified, structured, and up-to-date stream of product data across every Shopify store. This is really the foundational infrastructure for real-time, AI-powered commerce agents.
ChatGPT is now among the first tools to integrate with this API. The result is an experience where consumers can have a full conversation about what they’re looking for, refining by style, price, occasion, material, or even ethical considerations, and get product recommendations tailored to their exact request.
Want to find “a wedding guest dress under $250 that’s not fast fashion, in a color that flatters warm undertones”? ChatGPT now has the tools to respond accurately and instantly.
This isn’t just about smarter recommendations. It’s about changing the surface area of discovery. The entire funnel, search, compare, decide, and buy, is collapsing into a single interaction.
When a user prompts ChatGPT with a product-related request, the system parses that intent and constructs a query against its integrated product feeds. Instead of guessing at results from cached or outdated data, it accesses the live feed—pulling products that match the request across filters like price, category, material, or brand.
These results can then be enriched by the model’s reasoning capabilities. ChatGPT doesn’t just say “Here are some sneakers.” It says, “Based on your need for lightweight shoes for long-distance running, I’d recommend these models. They’ve been positively reviewed for cushioning and have breathable mesh uppers.”
The interaction doesn’t stop there. Users can refine the search further, just like they would with a personal shopper. “What if I want something more sustainable?” or “Can you show me options in white instead?” Each of those requests triggers a new query, dynamically updating results.
This is what makes Chat GPT product search different from standard search engines. It’s not a list, it’s a loop.
If you’re a marketer, this shift has huge implications. Product search is no longer about winning a single keyword, it’s about being structured, accessible, and ready for AI-powered conversations. And it starts with your product feed.
For years, brands have been told to invest in SEO, optimize for Google Shopping, and create custom audiences for retargeting. Those strategies still matter, but now there’s a new layer: optimizing your catalog data for LLMs.
That means more than just filling out your product title and price. Brands that will win in this new environment are the ones who:
The platforms that understand this shift early will be the ones who dominate the next era of product discovery. If search is moving into conversation, your feed is your pitch.
For shoppers, this experience is far more intuitive. Instead of opening a dozen tabs, scrolling through filter menus, and comparing specs manually, they can just talk.
Want a gift idea for a new dad who loves coffee and cycling? ChatGPT can pull options based on nuanced lifestyle traits, not just keyword matches. Looking for a nightstand that matches an oak bed frame and fits a 20-inch lamp? The model understands spatial constraints and aesthetic cues. This level of personalized discovery was never possible with static search.
And because these interactions are powered by real-time product feeds, the friction between consideration and conversion is lower. You’re not being shown out-of-stock products or irrelevant listings. You’re being met with tailored options that reflect the current state of inventory.
The Shopify and ChatGPT partnership is the beginning. Every e-commerce platform is now on notice– if they want their merchants’ products to be discoverable in the age of conversational AI, they need to invest in clean, structured, real-time data feeds.
Listing products on your site is no longer enough. To stay competitive, brands need to ensure their product data can plug seamlessly into the broader ecosystem of AI-driven discovery tools. Product feeds have evolved from a backend necessity into a powerful front-facing asset, fueling visibility, personalization, and performance across every digital surface.
We imagine that other platforms like BigCommerce, WooCommerce, and Salesforce Commerce Cloud will follow suit with their own API-driven feed integrations. Expect marketplaces like Etsy and Walmart to push for better feed compliance. And anticipate that Google, Meta, and Amazon will double down on making their search surfaces smarter through feed ingestion and LLM partnerships.
In the same way that SEO transformed how sites were built in the 2000s, product feed optimization is about to become the cornerstone of e-commerce growth in the 2020s.
At Marpipe, structured product data isn’t just a backend requirement, it’s the foundation for how high-performing ad creative gets made, tested, and scaled. Our Catalog Ad Creative platform turns your product feed into a living design system, auto-generating on-brand creative for every SKU and placement.
Rather than manually building ad variants, marketers can use Marpipe to generate dozens—sometimes hundreds—of creative combinations using real-time product attributes like price, category, color, and seasonal relevance. Each design adapts seamlessly across formats, from Meta carousels to Story placements, all mapped directly to your catalog.
But the real advantage comes from what happens after launch. With Marpipe’s Product Optimization tools, performance marketers can see which specific products and creatives are driving results—by ROAS, AOV, conversion rate, or engagement. The platform helps you automatically prioritize bestsellers, feature high-margin items, and pause underperformers—all within your catalog ads.
In other words, Marpipe closes the loop. Your product feed powers creative. That creative drives performance. And that performance data feeds directly back into how you promote, optimize, and scale.
While ChatGPT is opening the door to new discovery surfaces, Marpipe ensures what consumers find there is not only accurate, but persuasive, branded, and ready to convert.
We’re entering a new phase of e-commerce where the old playbooks like SEO tricks, static feeds, keyword-heavy titles, aren’t enough anymore. Shoppers aren’t just searching for simple keywords and phrases. They’re asking and refining by having real-time conversations with AI about what they want, need, and expect.
In this new landscape, product discovery doesn’t start on your homepage. It starts in a chat window.
Structured product data is quickly becoming the bridge between intention and action. The brands that take it seriously, investing in clean, comprehensive, machine-readable catalogs, will be the ones who show up first, show up accurately, and show up persuasively.
Whether it’s ChatGPT, Google, Shopify, or the next generation of agent-led tools, one thing is clear: your product feed is now your storefront, your pitch, and your competitive edge. And as ChatGPT product search becomes a more common entry for online shopping, the brands that invest in clean, well-structured product data will be the ones who appear in results, match real customer intent, and convert faster.
