Where Curio stops
Curio is a collector's tool: a photo becomes an identification, a story and a catalog entry, with an estimated value range. That is a good fit for learning about a piece. It is not built to tell you what the piece sells for this month or to get it listed.
What a reseller needs after the identification
Underpriced AI prices from recent completed sales, shows those comps, and gives a calibrated range with three list prices and a two-week sell chance. It writes the eBay title, description and item specifics, publishes to eBay in 10 markets or Bonanza, and tracks the item through to profit.
Choose Underpriced AI if you
- Want to know what a piece sells for, not only what it is
- Sell on eBay or Bonanza and want the listing written for you
- Price everyday items as well as antiques
- Use Android or a desktop browser
Curio may fit if you
- Collect rather than sell
- Want the history and story behind a piece
- Keep a personal catalog on an iPhone
