What is grocery-shopping-redmart?

This project is not a traditional app you install and run. It is a set of instructions and a small product catalog meant to be used together with the ChatGPT desktop app and its built in browser, to help a family fill an online grocery cart on RedMart, a Singapore grocery delivery service. The idea starts with a simple family problem: once a household has already decided which brand of eggs, detergent, or snacks it usually buys, repeatedly finding those same products and adding them to a cart every week feels like a waste of time. This project lets a family send a grocery list as a photo of a whiteboard, a dictated voice note, or typed text. The AI agent then matches those everyday words, like rice crackers or big garbage bags, to the family's usual saved products, checks that each one is in stock, fills the cart, and reads the cart back to confirm the products and quantities are correct. Importantly, the agent stops there. It does not choose a delivery slot, does not go to checkout, and does not pay. The person still reviews the proposed cart, can correct or skip items, and completes the order themselves. Setup involves installing the ChatGPT desktop app on a Mac or Windows computer, signing into RedMart or its parent site Lazada directly in the app's browser, and optionally connecting the ChatGPT mobile app so a grocery list can be sent from a phone while the actual browser work happens on the desktop computer. A family builds its own product catalog once, using its past RedMart orders as a starting point, and can add newly bought products later the same way. The project itself is free to use, though it depends on having a ChatGPT plan that includes the built in browser feature, and the household still pays RedMart directly for groceries ordered.
