Your card collection, sorted.
Scan your cards, know what they're worth, and buy smart at shows. Built by a collector for himself and his kids.
Scan a stack, skip the typing
Snap cards on your phone or run a duplex scanner. Grailhouse reads the number and serial stamp and fills in the rest from the set's checklist, down to the parallel.
Show check
At a show or shop: snap or type the card, see what it's asking and selling for on eBay in one tap, whether you already own it, and what to offer.
Your collection, the way you collect
Sport, team, player, then the cards. Set progress, rainbows and team sets, with what's missing and what it'd cost to finish.
For the kids too
Each kid gets their own collection and team sets, trades that a parent approves, and Buddy, a card-smart helper they can ask anything.
Breaks, tracked
Log every break spot, mark the skunks, and see if you're really up or down, by breaker, set and team. A live calculator tells you what a spot is worth while the countdown runs.
Sell when it's time
Sell and cooling signals from recent sales, a listing queue and an eBay upload file, and profit that knows what you paid.
Private beta
Grailhouse is free while it's in beta. Each household gets a monthly allowance of AI for photo reads and Buddy; typing cards in, Show check's eBay searches and everything else don't use it. Got an invite code? Join here.
