Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureMost stores aren’t visible to LLMs because their content sits hidden behind themes and CMS layers. Our app fixes this by exposing your catalog dynamically in a format LLMs can read and use. It creates AI-ready sitemaps, structured metadata, and live endpoints that LLMS love and pick up. You can add custom prompts that guide how your store is described, giving you control over how AI presents your products.
Shoppers now ask ChatGPT, Copilot and Perplexity what to buy. Sigourney publishes your own catalog as clean product data on public pages that AI search assistants can read, with links back to your store, and only after you agree. It checks each product against what ChatGPT, Google Merchant Center and Shopify Catalog require and tells you where in your admin to fix gaps.
