Questions & Answers

As answered by people managing Underpriced AI and StackMail.

What's the story behind your product?

Underpriced 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 — 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.

What makes your product unique?

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 — not both. You get identification, fair market value, comparable sales, and a ready-to-post listing from one photo.

Why should a person choose your product over its competitors?

Underpriced AI's answer

Pricing is based on actual sold data across eBay, Poshmark, Mercari, Facebook, Etsy, and Depop — 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.

How would you describe the primary audience of your product?

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.

Which are the primary technologies used for building your product?

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.

Who are some of the biggest customers of your product?

Underpriced AI's answer

  • Independent resellers and thrift flippers
  • Antique and vintage dealers
  • Estate sale professionals
