About this app

Grail Swap is the marketplace and collection manager for trading-card collectors. Build your vault, track what it's worth, and buy, sell, or trade with collectors near you.

WHAT YOU CAN DO

- Vault — catalog your collection with condition, grading (PSA, BGS, CGC, and more), photos, and notes. See your estimated portfolio value with a per-card breakdown and price sources.

- Scan fast — point your camera and rapidly capture a stack of cards; AI fills in the details for you to verify.

- TradeSquare — one place to buy, make offers, or trade. List a card for sale, for trade, or both.

- Chain trades — when a direct swap isn't possible, Grail Swap finds multi-person trade loops from everyone's want lists so three or more collectors can all get a card they want.

- Want list + matching — get notified when a card you're after is listed nearby or within your price.

- Prices — market values based on current eBay asking prices, with the source and matching listings shown.

- Local deals — meet up in person to hand off the card, and pay the seller directly with cash, Zelle, or Venmo.

SAFE & RESPECTFUL

Grail Swap has zero tolerance for objectionable content. You can report or block any listing, message, or user, and our team reviews reports within 24 hours.
