Bring the 3 to your iFood.

You pay three times for food: the food, the fees, and the difference to the cheapest option. The extension shows all three on every shop, product and bag, and takes you to the item worth buying.

On your phone?

The extension runs in a desktop browser. On a phone you can already send a screenshot of the menu to Claude with the UPAY3FOOD connector: Claude reads the items and UPAY3FOOD does the math per litre and per gram. The link to the item opens straight in the iFood app.

Plug it into Claude or ChatGPT →

The extension’s interface is in Portuguese, for Brazilian iFood users.
