Know which box every card is in

When a bin is full, empty it into a storage box and Mault records each card's exact position in the stack. Search every box by name, see what each one is worth, and export a box as CSV.

Buy collections over the counter

Scan a customer's cards into their own intake and watch a cash and store credit offer build from your buylist tiers. Cards below your minimum are struck out, and accepting records what you paid and prints a receipt.

01.05 / Sort any way you like

  • Instant recognition

    No typing card names, no barcodes. The feeder puts each card in front of the camera, and Mault knows exactly what it is.

  • Reads the card text

    When two printings look alike, Mault reads the name, set and number to tell them apart.

  • Auto bin assignment

    Skip the rule-writing. Pick a field like rarity or set, and the first card with a new value claims the next open bin. Repeats route back automatically.

  • Alphabetical sorting

    Sort a pile A to Z, one letter per bin. Then drill into any pile, A into AA, AB, AC, until every card is in order.

  • Build repacks

    Define pack slots per bin, like 3 commons and 1 rare, and every bin fills its own pack at the same time. Empty it to start the next one.

  • Pull cards from a decklist

    Paste a decklist into any bin and Mault pulls those cards out of the pile as they're scanned, crossing each one off until the list is complete. Everything else sorts as usual.

  • Chaos sort

    Fill bins in order, no rules needed, then empty each one into a box when it's full.

01.06 / Built for card shops

  • Pick online orders from your boxes

    Paste a TCGplayer pull sheet, a Shopify export or a plain list. Mault finds each card and tells you which box and position it is in, then takes the picked cards out of your inventory.

  • Prices from three markets

    Value your collection with TCGplayer, Cardmarket or Card Kingdom prices, refreshed daily. Set each card's condition and its price adjusts to match.

  • Spot checks

    Check a random sample of a batch and get an accuracy estimate with a 95% range before you list it.

  • Staff activity

    See scans and corrections per person, and a log of who changed what.

  • Buy prices stay private

    Let staff scan intakes without seeing offers, costs or margins.

  • API and webhooks

    Connect your shop: look up where any card is stored and get notified as cards are scanned.

  • Sorter alerts

    Get told on Discord or by webhook when a sorter jams, goes offline or is due for service.

01.07 / Grows with your setup

  • Built for the table

    Pairs with a physical sorter, so your cards land in real bins, not just another spreadsheet. Add more sorting modules any time to grow up to 11 bins.

  • Several sorters at once

    Run more than one sorter from a single browser tab, each with its own camera and collection.

  • Overflow bins

    When a bin fills up or hits its copy limit, the next card spills into the bin you pick.

  • Every language

    Scan cards in other languages, or mix them all in one collection.

  • Watch from your phone

    Follow a scan session live from anywhere, or share a read-only link with a friend.

  • Discord alerts

    Post every scan, or only the cards that match your rules, to your server and ping a role.

  • Custom sounds

    Upload your own clips and play them when a matching card is sorted, like a fanfare for every mythic or a cha-ching for anything over $20.

02 / Open source

Fully open source

The software and the physical sorter are both free to build, inspect, and tinker with. Grab the code and print one of your own.

02.01 / Source code

The web app, API, and sorter firmware all live together in one repo, under an open license.

View on GitHub

02.02 / 3D printable sorter

Print your own card sorter at home. Fusion 360 and 3MF files are right there in the repo.

02.03 / Community

Join the Discord to share your build, get a hand when you need it, and chat with others running their own sorter.
