What’s That Worth? is a free, AI-powered online item valuation tool that helps you estimate the resale value of almost anything — from electronics and collectibles to vintage games, clothing, and more.
It works by scraping recently sold UK listings and filtering out inconsistent or irrelevant prices using a statistical method to remove outliers. Then, it calculates the average market value and provides a short, friendly AI-generated summary that considers condition and context.
Whether you're planning to sell on eBay, Gumtree or Facebook Marketplace, declutter your home, or just curious about the second-hand value of an item, this tool gives you real-time resale insights in seconds.
