Querytail is a conversational AI sales assistant that understands your catalog, guides your customers and converts them, on-site and off-site.
Most AI commerce tools stop at the catalog: they enrich product data and publish it to LLMs. Querytail goes further. We built the full conversion stack: an on-site Agentic Client Advisor that understands buyer intent and closes the sale, an in-chat checkout that keeps the merchant in control, and a self-improving data engine that compounds with every interaction. We don't just make your products discoverable by AI. We sell them.
We build the infrastructure that lets every e-commerce brand sell through AI agents, on their own terms: their data, their brand voice, their checkout, their customer relationship. No intermediary. No black box.
