Snap an English Pokémon card and see what it is worth — the exact printing, in seconds. Base Set, Shadowless or 1st Edition? GrailFox narrows it to the exact printing, asks you to confirm when two look alike, and shows what that printing sells for — with the source and date of every price. Three free scans. No account. WHY GRAILFOX • Exact printing, confirmed with you. GrailFox reads your card, then checks the match against the card catalog by set, number and printing. When two printings genuinely look alike, it shows you the candidates and asks you to confirm. • Honest prices. You always see where a price comes from and how fresh it is. • Your collection, valued. Save cards with quantity and condition, see the total value and how it changed this week. • Your photos. The collection shows the cards you actually photographed — your copy, in its real condition, not a catalog image. HOW PRICING WORKS Your first three scans are free — no account, no sign-up. After that: • GrailFox Pro — US$39.99/year, or US$4.99/week; up to 500 scans a month either way. • Single scan — US$0.99 for one extra scan whenever you need it. Prices in other regions may vary; the exact price is always shown before you buy. A scan is only spent when a card is identified. A failed scan costs nothing. WHAT GRAILFOX IS NOT It identifies English-language Pokémon trading cards only — no Japanese or other-language printings, no sports cards and no other card games. When GrailFox cannot identify a card, it says so, and an unidentified scan is never charged. PRIVACY No account, no email, no password. Card photos are used to identify the card — the Privacy Policy explains exactly what happens to them: https://grailfox.net/privacy SUBSCRIPTION DETAILS GrailFox Pro is an auto-renewable subscription, billed yearly or weekly.
