Hey Product Hunt! I built Underpriced AI because my wife and I kept finding interesting items at thrift stores and estate sales but had no idea what they were worth. The research process was brutal — Google it, search eBay sold listings, compare conditions, try different keywords... 15-20 minutes per item minimum. Now we just snap a photo and know in seconds. How it works: 1. Take a photo of any item (up to 3 photos for maker marks, labels, condition) 2. AI identifies it — brand, model, era, materials, condition 3. See recently sold listings from eBay, Poshmark, Mercari, Facebook, Etsy, and Depop 4. Every comparable sale has a clickable link — so you can verify the prices yourself 5. One-click publish to eBay with an AI-generated title and description What I'm most proud of: - Transparency over trust. We don't just give you a number — we show you the actual sold listings that number is based on, with links. You decide if you agree. - Cross-platform data. Searching one marketplace gives you a biased picture. We search six. - Scan to listed in 60 seconds. Identification → pricing → listing generation → eBay publishing, all from one photo. - Estate Sale Finder searches EstateSales.NET, EstateSales.org, and Craigslist so you can find deals near you. - iOS and Android apps work at the thrift store — scan before you buy. We're bootstrapped and self-funded. Free trial is 3 scans, no credit card, no time limit. I'd love your honest feedback. What would you use this for? What's missing? — Frank
