What ThriftAI covers
ThriftAI is a scanning app on iOS and Android: photograph or scan an item, get a value from marketplace sales data, and run the fees through a profit calculator with scan history. Its public material does not name the sources behind the value or describe listing tools, so those rows read as not stated.
What Underpriced AI adds
The comps are shown, from recent eBay sold listings backed by an automatic backup source and our own archive of past sales, with a calibrated range, three list prices and a two-week sell chance. The same scan produces an eBay title, description and item specifics, publishes to eBay in 10 markets or Bonanza, and fills the listing form on Facebook Marketplace, Poshmark, Mercari and more through a free browser extension.
Choose Underpriced AI if you
- Want to open the sold listings behind a price

- Work from a desktop as well as a phone
ThriftAI may fit if you
- Only need a quick value and a profit number in the aisle
- Scan mostly barcoded retail items
- Do not list from the app
Common questions
How is Underpriced AI different from ThriftAI?
Both scan an item and estimate its resale value with a profit calculator. ThriftAI stops there. Underpriced AI shows the sold comps behind the price, gives a calibrated range with three list prices and a two-week sell chance, then writes the listing and publishes it to eBay or Bonanza.
Is Underpriced AI more accurate than ThriftAI?
We do not claim to know ThriftAI's accuracy. We measure ours against independent sales and publish the method. Every price also shows the comps it came from, so you can check it on the spot instead of trusting either app.
What does ThriftAI cost compared to Underpriced AI?
On the App Store on 2026-09-16, ThriftAI was free to download with Premium at $9.99 a month or from $19.99 a year. Underpriced AI gives a free first scan, then plans from $5 a month or a $3 pack with no subscription.
Does Underpriced AI have barcode scanning like ThriftAI?
Underpriced AI identifies from a photo, so it works on unlabeled, vintage and handmade items as well as barcoded ones, and it reads a barcode or ISBN when one is in the photo. ThriftAI's listing describes barcode scanning too.
