Build me a voice first shopping app called Voider that lets people just say what they want and have the app do the rest. It should listen to a request like get me a 12 pack of Red Bull or I am hungry find me something nearby, search across multiple shopping and delivery options at once, compare the real total price including fees, and show the best choice in a simple clean UI with product cards. I want it to remember favorites and the usual items, respect budget limits, and make recommendations based on location, past orders, and preferences. If the exact commerce or payment pieces need current docs, look them up online and wire them in cleanly. Make the experience feel fast and polished, with a strong focus on voice, low friction checkout, and a modern shopping flow that feels almost hands free.
