From conversation to commerce
A shopper describes a need → discovers relevant products → compares options in your app → continues to an eligible checkout or your store.
Your branded ChatGPT app
Give shoppers an interactive way to explore your products inside a conversation. An MCP server connects catalogue tools to an MCP App, so the experience can show product cards, variant choices and contextual actions. CartmelAI helps shape the tools, interface and brand experience around your catalogue.
ACP: connect product discovery and commerce
Prepare structured product feeds and supported commerce endpoints for the Agentic Commerce Protocol. Product discovery and checkout are separate integration steps. We help map your catalogue and buying flows, validate responses and define the appropriate handoff for your eligible markets.
GEO: make your products easier to understand
Generative Engine Optimization starts with useful, consistent product information. We help improve attributes, product explanations and buying guidance, then test representative shopper questions. Better information supports discovery; placement and recommendations remain controlled by the platform.
WebMCP: make your storefront actionable
Expose structured actions on your own website for compatible browser agents. A shopper can move from advice to a merchant-controlled journey using the current site context. We help define and test actions such as finding products, selecting variants and preparing a basket.
Launch with a measurable journey
Connect your store, choose the experience and validate it with real shopper scenarios. CartmelAI brings catalogue preparation, integration work and ongoing monitoring together, so you can track where shoppers discover products and where they continue buying.
Plan your launch with CartmelAI
App distribution and ACP shopping features follow OpenAI review, merchant eligibility and market availability. WebMCP is a separate browser integration, dependent on the client and browser.
