Collector Core is a platform designed to help trading card game collectors manage their collections from one connected space. It supports Pokémon, Magic: The Gathering, Yu-Gi-Oh!, One Piece, Lorcana, Digimon, and Riftbound, with catalogs of cards, sets, and products that are expanded over time. Its scanner can identify multiple cards in a photo and prepare matches for the collector to verify before saving. Users can organize individual copies, track set completion, create wish lists, and record where cards are stored, including in binders, storage boxes, and graded cases.

The platform also provides collection value estimates with market coverage, sources, and historical trends, while making clear that figures are contextual estimates rather than guaranteed sale prices. Additional tools include watch features for following listings or prices, community showcases, collection milestones, and workflows for preparing sales listings on eBay and CardTrader. Collectors can begin with simple tracking and add detailed information such as condition, grading, purchases, photos, and movements as needed.
