Commerce-Native AI Behind Every Collection, Search, and Recommendation.
Fast Simon learns from what shoppers browse, search, and buy, then weighs that behavior against what your business needs, like stock levels, new arrivals, and margin. That's what makes it Commerce-Native AI. A single model handles product discovery across your site. It ranks collection pages, search results, and recommendations, and runs your AI shopping agents, so everything works from the same data and the same merchandising strategy.

FAQs
What Is AI Product Discovery?
AI product discovery is how shoppers find products on an online store (through collection pages, search, recommendations, and conversations), with AI deciding what each shopper sees. Fast Simon combines AI merchandising, personalization, search, and shopping agents, so every one of those touchpoints uses the same data and follows your merchandising rules.
What Is an AI Shopping Agent?
An AI shopping agent is an assistant on your storefront that shoppers talk to in their own words. The AI shopping agent answers questions, recommends products, and guides the shopper to checkout, which is the core of conversational commerce. Fast Simon's AI shopping agents work from your catalog, promotions, and merchandising rules.
Does Fast Simon Replace My Merchandising Team?
No. Your merchandisers set brand strategy, visual rules, and campaign priorities. Fast Simon's AI ranks and personalizes products within those rules and takes over the manual sorting, so your team spends its time on strategy.
Can Merchandisers Override the AI?
Yes. Merchandisers can pin, boost, bury, or hide products in search results and on collection pages with a visual drag-and-drop editor. Campaign rules and business logic always come first, and AI optimizes the ranking underneath.
Do We Need Developers to Implement Fast Simon?
No. On Shopify, Fast Simon installs as a native app and launches without custom code. Brands with headless storefronts or mobile apps can use the Fast Simon SDK and APIs.
Will Fast Simon Work With Klaviyo, Attentive, and Our Other Tools?
Yes. Fast Simon connects with the email, SMS, reviews, and mobile tools you already run, so there is nothing to rip and replace. Shopper behavior from your storefront and those channels feeds one AI model, so on-site experiences and campaigns improve from the same data.
Does Fast Simon Slow Down My Storefront?
No. Fast Simon is built for sub-second response times and serves results through a global content delivery network, so pages stay fast for shoppers.
How Do We Measure the Revenue Impact?
Fast Simon includes built-in analytics and A/B testing. Merchants track search conversion, average order value, and search-assisted revenue against their own baseline, without a separate attribution tool.
