AI Garage Sale is a unique platform that uses artificial intelligence in a form of a digital marketplace. Unlike typical online commerce websites, this tool gives a novel twist to the buying process by allowing users to haggle for products with an AI tool. It handles a wide variety of products including, but not limited to, concert tickets and gaming consoles. The main objective of AI Garage Sale is to provide a dynamic pricing model rather than a fixed price, engaging users in a bargaining process. Buyers have the opportunity to negotiate down the price, making online shopping more interactive and gamified. It's also worth noting that while the system allows for negotiation, it incorporates a fairness aspect by encouraging users not to drive prices down excessively. This tool, created by BRAIN?, demonstrates an innovative use of AI within the e-commerce sector, adding a competitive and fun edge to the online shopping process.
