Description
Hey HN, I built Underpriced AI to solve a problem I had as a part-time reseller: standing in a thrift store trying to figure out if something is worth buying. How it works: - Snap a photo of any item - AI identifies the brand, model, maker, era, etc. - Pulls recent sold prices from eBay and other marketplaces - Gives you an instant valuation with confidence score You can also generate SEO-optimized eBay listings and publish directly from the app. Tech stack: Next.js, Claude API for vision/analysis, eBay API for market research and listing. The "Quick Scan" feature is designed for mobile – get a price check in seconds while you're out sourcing. Free tier available. Would love feedback from anyone in the reselling space or who's worked on similar pricing/valuation problems. https://underpricedai.com

Could you build this?
Yes The application is a standard mobile/web wrapper that captures an image, queries a multimodal LLM (like Claude) for item identification, and queries marketplace APIs (eBay, Mercari) for sold comps.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
