Basement

Scan collectibles, follow market listings, and organize your collection

Meet Basement

Basement is a collector app for iPhone with a companion Chrome extension. Users can scan trading cards, add other collectibles such as graded cards, sealed products, games, and LEGO, and organize them in a collection with pricing information. Its tools also surface card prices while viewing supported live shopping streams.

A watchlist lets collectors specify items of interest and set limits for an AI shopping agent. Collector rooms add conversations around listings, while Basement Light brings those rooms into Chrome. The app combines collection tracking, market research, and shopping assistance in one place, giving collectors context before deciding what to add or sell.
