Can I scan a barcode instead of taking a photo?

Yes, though you rarely need to: put the barcode in one of your photos and the scan reads it. If a book or record shows only a few sales, tap "Scan its barcode" on the result. We look up the title using Google Books for books and Discogs for music, then price it from real sold listings. For everything else, a clear photo is more accurate.

How do I scan several different items at once?

Add up to 10 photos on the scan page, one photo per item, then tap "Each photo is a different item" when the scan page asks. Each photo is identified and priced separately, and each counts as its own scan toward your limit. Adding multiple photos of the same item to one scan is different and counts as a single scan.

Can I scan an item from a website on my computer?

Yes, with the browser extension. Install it, then right-click any item photo on a listing or webpage and choose "Scan with Underpriced AI". Extensions do not run in phone browsers.

Ways to scan: camera, upload, barcode | Help

Ways to scan: camera, upload, barcode

Ways to start a scan: phone camera, gallery upload, a barcode in your photo, up to 10 different items at once, and the desktop browser extension.

There is more than one way to get an item into Underpriced AI. Pick the one that matches where you are and what you are holding.

Camera or gallery upload

On the scan screen, tap "Take Photo" to use your phone or computer camera, or tap Upload to pick an image already in your photo library. Both run the same analysis. You can add up to 12 photos of the same item, the first 3 read for the price, to one scan, and it still counts as a single scan.

Barcodes for books, CDs, and vinyl

There is no separate barcode step to remember. Get the barcode (a book's ISBN, or a CD or record's UPC) into one of your photos and the scan reads it. When the barcode's record and what the scan sees in the photo agree, the record names the item. When they do not, the scan prices it from the photos as usual.

If a book or record comes back with only a few sales, the result offers "Scan its barcode" so you can scan the exact edition. We look the title up, using Google Books for books and Discogs for music, then price it from real sold listings exactly like a photo scan. For clothing, collectibles, electronics, and housewares, a clear photo works better.

Batch scan for a pile of items

On the scan page, add up to 10 photos, one photo per item.
When the page asks "One item, or scan each photo separately?", tap "Each photo is a different item".
Each photo is identified and priced as its own separate item.

Batch is built for clearing a pile fast. Each item counts as its own scan toward your limit. This is different from adding several photos of the same item to one scan.

Desktop options

Install the Chrome or Firefox extension and you can right-click any item photo on a website, an auction listing, or a marketplace page and choose "Scan with Underpriced AI". Extensions run on desktop Chrome and Edge, not phone browsers.

Which one should you use

Use the camera when you are standing in a thrift store or estate sale. For books and media, get the barcode in the photo. Use "Each photo is a different item" when you get home with a haul. Use the extension when you are shopping online listings from a computer.
