Underpriced AI

What is Underpriced AI?

Underpriced AI is an app that lets you snap a photo of any item and instantly get AI-powered valuations based on real sold data from eBay, Poshmark, Mercari, and other marketplaces. It helps resellers, thrifters, and collectors price items accurately and create optimized listings.

How does AI item scanning work?

Take a photo of your item with your phone camera. Our AI identifies the item, brand, model, condition, and era - then searches recently sold listings across eBay, Poshmark, Mercari, and other platforms for real-time pricing. You get comparable sales with links so you can verify the prices yourself.

How much does Underpriced AI cost?

Plans start at $5/month for 15 scans (Starter), $12/month for 40 scans (Pro), $24/month for 85 scans (Pro Plus), or $59/month for 250 scans (Business). Every scan runs on Claude Opus 4.7, Anthropic's most capable vision model. You can also buy individual scan credit packs without a subscription, starting at $0.99 for a single scan.

What marketplaces does Underpriced AI support?

Underpriced AI pulls pricing data from eBay, Poshmark, Mercari, Facebook Marketplace, and Depop, plus auction archives like LiveAuctioneers, Heritage, and Christie's for collectibles and vintage items. You can create and publish listings directly to eBay (10 countries: US, UK, Canada, Australia, Germany, France, Italy, Spain, Netherlands, Belgium) and Bonanza, with pricing data localized to your marketplace and currency.

How accurate are the AI valuations?

Our valuations are based on real recently sold data from eBay, Poshmark, Mercari, and other marketplaces - not estimates. Every scan includes comparable sold listings with links so you can verify the prices yourself. The AI provides low, suggested, and high price ranges based on actual transaction data.
