Why Grimoire

Collection-first, AI-native

Most tools start with the deck. Grimoire starts with your cards — then makes everything else owned-aware.

Catalogue your collection

Track every card you own — quantity, finish, condition, and what you paid — across binders, backed by real Scryfall data.

Owned-aware deck building

Build decks straight from your collection. Grimoire highlights what you already own and totals up only the cards you still need.

AI deck coach

It researches the real meta — EDHREC, Commander Spellbook combos, the web — then builds owned-aware decks with reasoned adds, a buy plan for what you're missing, plus primers, analysis, and an honest roast.

Playtest your pod

Take a deck for a spin in a real 4-player Commander pod online with friends, or solo-goldfish against test bots to learn the lines before game night.

Value & price tracking

See your portfolio's value move over time, track gains since purchase, and keep an eye on what your decks are worth.

Free, with AI credits

Everything but AI is free forever. AI actions run on credits — new accounts get a free grant, and Supporter ($4) or Pro ($10, unlimited on Opus) keep you brewing. Refer a friend and you both get a credit.
