What is CommerceGPT?
CommerceGPT is an AI engine built to power the entire shopping experience from search, to discovery, to conversion. These engines use generative AI intelligence that is trained on commerce data to be able to deliver conversational shopping experiences that represent the nuance typical search behavior entails.
Unlike traditional search and recommendation tools, CommerceGPT goes beyond simple keyword matching or static suggestions. By understanding shopper intent, product attributes, and historical interactions it can provide highly personalized guidance throughout the buying journey. From answering questions about products, suggesting alternatives, to guiding customers toward checkout, CommerceGPT acts as an intelligent shopping assistant, making discovery faster, decisions easier, and the overall experience more seamless.
How Does CommerceGPT Work?
CommerceGPT transforms every shopper interaction (search, browse, recommendations) into a context aware experience that understands intent.
Unlike general purpose LLMs that are trained on vast but generic internet data, CommerceGPT is built on your customers, your products, and your data to truly understand your shoppers, closing the data gap that retailers face when competing against AI-native platforms and retail giants like Amazon. This results in more relevant results for your customers and higher conversion rates (and revenue) for your business.
For example, if a shopper searches for “winter jackets for Boston,” CommerceGPT can surface products that meet the cold-weather criteria, highlight options in the shopper’s preferred size and color, and even suggest matching accessories. AI co-pilots can answer follow-up questions like, “Is this jacket waterproof?” or “Does it have a removable lining?” This creates a personalized, conversational shopping experience that guides the customer from discovery to purchase.
How Does CommerceGPT Personalize Digital Experiences?
Buyers expect more than generic search results. They want experiences that feel intuitive, relevant, and context-aware. Traditional personalization approaches, whether rule-based recommendations or basic search filters, can’t keep up with the complexity of modern shopper behavior. CommerceGPT leverages AI trained specifically on your products, customers, and behavioral data to understand not just what shoppers are searching for, but why they’re searching for it. This enables a truly personalized digital experience that adapts in real-time.
CommerceGPT combines the best of AI personalization and search optimization. It tailors product recommendations, answers follow-up questions, and dynamically adjusts search results based on shopper intent, past behavior, and contextual signals. For example, if a shopper searches for “eco-friendly running shoes,” CommerceGPT can highlight sustainable options in their size, suggest complementary gear, and provide details about material or performance all in a single, seamless experience.
Why This Matters for Retailers
- Closing the Data Gap: Retailers often struggle to compete with AI-native platforms because they lack insight into shopper intent and behavior. CommerceGPT leverages your own first-party data to bridge that gap.
- Scaling Personalization: Unlike static rules, CommerceGPT continuously learns from interactions, enabling real-time personalization across search, browse, and recommendations at scale.
- Driving Conversions: By serving relevant results and guiding shoppers through the buying journey, CommerceGPT increases engagement, conversions, and revenue all while creating a smoother, more satisfying shopping experience.
- Future-Ready Commerce: Beyond improving today’s shopping experience, CommerceGPT positions your business for next-generation commerce, where AI-powered assistants can interact directly with customers and other systems in a context-aware way.
How Cimulate Builds Your CommerceGPT
Every retailer has their own ecommerce goals, their own unique product catalog, and their own customers, so their search should be unique too. Cimulate builds a custom CommerceGPT for every one of our customers, fine-tuned to their audience.
Using a method called distillation via simulation, part of building our CommerceGPT model involves simulating shopping behaior to create synthetic data:
- We use our customers’ products to build personas that simulate millions of shopper journeys.
- We then turn that into synthetic data that understands not only what products these shoppers chose, but also why they chose them
- We fine tune this model with our customers own data, their customer behavior and product catalog, and customize it to match their business goals.
- This custom CommerceGPT will continuously retrain itself to improve accuracy.
Cimulate integrates with your existing infrastructure in weeks, not months. Our APIs and MCP Server make it simple to power AI-native experiences across your site, app, and emerging agentic commerce channels.
