Underpriced AI identifies items from photos using AI vision and web search, then pulls recently sold prices from 6+ resale marketplaces to give you an accurate fair market value โ not just asking prices. Built for thrift flippers, estate sale hunters, antique dealers, and anyone who needs to know what something is worth before buying or selling. Features include multi-photo scanning for maker marks and details, one-click eBay listing, inventory management, donation valuation reports for tax documentation, and an estate sale finder. Pay-as-you-go with scan packs starting at $4, or subscribe from $12/month.

Underpriced AIUnderpriced AI's answer:
My wife flips thrift store and estate sale finds, and I watched her spend 10+ minutes researching every item on her phone before deciding to buy. I'm a software engineer, so I built a tool to do it in seconds โ snap a photo and know what it's worth. What started as a side project to help her source faster evolved into a full reseller workflow: scan, price, list, and track.
Underpriced AI's answer:
It's the only tool that combines AI image recognition with real sold price data from 6+ marketplaces in a single scan. Most competitors either identify items OR look up prices โ not both. You get identification, fair market value, comparable sales, and a ready-to-post listing from one photo.
Underpriced AI's answer:
Pricing is based on actual sold data across eBay, Poshmark, Mercari, Facebook, Etsy, and Depop โ not just eBay asking prices. There's no monthly commitment required; you can buy a 5-scan pack for $4 and try it. It also goes from scan to eBay listing in two clicks, which no other pricing tool does.
Underpriced AI's answer:
Thrift store flippers, estate sale buyers, antique dealers, online resellers, and anyone who buys and sells secondhand goods. Also useful for people valuing donated items for tax purposes or settling estates.
Underpriced AI's answer:
Next.js, TypeScript, Claude AI (Anthropic) for image analysis, Perplexity AI for real-time market research, eBay Browse API for live listings, PostgreSQL, AWS, and Vercel.
