CPUmade is an AI-based tool that allows users to create and design their own unique t-shirts. The tool works by using an AI model to generate a personalized design based on the user's description of what they want to create. Once a design is chosen, users can customize the t-shirt's color and size and add it to their cart for purchase. CPUmade also offers a community section where users can browse and sort designs by popularity, as well as follow their favorite makers for updates on their latest designs.
