OtterDex, a card-price catalogue that refuses to guess

Field notes

OtterDex organizes trading-card values by printing rather than treating a card name as sufficient identification. Its public catalogue spans 176,354 printings in five games, with set-level pages that surface the 25 cards most worth pulling from a box. The planned scanner is designed to use the set code and collector number, then distinguish a confident match from several possible matches or an unreadable image. The homepage says collections remain on the phone and exportable.
