"longDescription": "Real store prices, checked in your own Chrome. Give Muchita Shopping an exact product name and variant, or a retailer link. Open the check in Chrome on your computer. If needed, install the Muchita Shopping extension once; your check then starts automatically.\n\nUse the live Muchita card in ChatGPT to open the check in desktop Chrome and see verified offers as stores are checked. Compare item prices and open an offer to buy directly from the retailer. Shipping is shown separately and does not change the item-price ranking. Unknown shipping is not treated as free.\n\nFresh price checks require desktop Chrome and the Muchita Shopping extension. They cannot run on a phone. No Muchita account or API key is needed. The hosted connection temporarily processes your chosen product, optional shopping country and check result, with stored check data deleted within one hour. Your conversation is not sent to Muchita.\n\nPrices and availability can change. Results cover the offers Muchita could verify during your check, not every offer on the internet. Muchita does not place orders or handle payments. Independent of OpenAI.",
