Everything here exists to get you from idea to a deck you can cut out and play — fast, and without fighting the tool.
A Card Data Template defines what every card tracks — name, cost, power, type, rules, art — with real field types (text, number, category, image, icon). A Layout Template defines how those fields look on the card. They live apart, so you can rebalance the whole game without nudging a single pixel, or restyle every card without retyping a word.
Drop a data column onto a slot and the card renders live — actual values, actual art, actual type sizing. X-Ray mode shows you the slot keys; Style mode locks them so you can focus on the look. No "save and refresh to see what happened."
Export print-ready PDFs with real card dimensions and bleed — pages you can run through a printer, cut, and sleeve. Snapshot PDFs come with a clean cover so a playtest packet looks like a playtest packet, not a spreadsheet.
One dataset becomes a full deck of rendered cards. Edit a row and the card follows. Bulk-edit in a table, paste a CSV, or tweak one card at a time — the deck stays in sync either way.
Version a game before a playtest, then go wreck the balance on purpose. If an idea face-plants, restore the snapshot and try the next one. Export the whole game as a single .playproof file to back up or hand off.
A searchable icon library for costs, types, and keywords, with a curated default set you can customize. Bring your own images too — focal-point crop keeps art framed right whatever the card size.
Playproof runs fully offline. Your games, data, and art live on your Mac — nothing's uploaded. Writes are atomic, so a crash mid-save won't corrupt your work.
