What is GrailHawk?
The 60-second overview of how GrailHawk works.
GrailHawk is a real-time price tracker for trading cards. You choose the exact Pokémon or One Piece printing you want and the most you'll pay; it watches qualified eBay and Shopify listings and alerts you when a matching listing reaches your target.
You do the valuation once. GrailHawk does the watching forever — so you never refresh listings again or miss a deal while you sleep.
The core loop
- +Search a card and compare its distinct printings.
- +Open the exact card, then create a watch with a target price and optional grade.
- +Get an email + in-app alert when a listing hits your price.
- +Tap the buy link to go straight to the listing on eBay.
- +Add what you own to Portfolio to track live value and P/L.
