Deckshift

Print what changed

Turn spreadsheet revisions into your next tabletop playtest. After playtesting, reimport your card CSV, review changes by stable card ID, and print the replacement cards. Earlier snapshots keep their card data and design together, so you can compare versions and return to prior work.

Try the free demo with your own deck

Up to 18 cards per deck and per saved revision, with real import, editing, snapshots, revision review, and unwatermarked PDF/PNG exports. Run the browser demo above or download the free demo ZIP below.

Full offline edition — $29 one-time

Up to 2,000 cards per deck and 100 saved revisions per project. No subscription or app account. Extract the complete ZIP and open index.html in Chrome. Save portable project files to move your work from the demo to the full edition.

• Map CSV columns and resolve missing or duplicate IDs before import.
• Accept individual field edits; omitted cards stay unless you explicitly accept removal.
• Use three configurable layouts with local artwork, font sizes, and visible text-fit warnings.
• Export a full deck or added/changed cards as printable PDFs with crop marks, individual PNGs, or printable sheet PNGs.

Scope and compatibility

Fronts only. No duplex backs or Tabletop Simulator sheets. Chrome on macOS is tested; other browsers and devices are unverified. Fonts can differ across devices. Print at actual size and measure a test page; physical printer accuracy, bleed, CMYK, and commercial press output are not certified. Portable project downloads are the durable backup; work in one active tab.

The full edition also has file and image limits documented in the included guide. $29 USD is itch.io’s minimum price for the full offline edition; optional higher payment adds no features. Purchases and refund requests are handled through itch.io.

Creation disclosure

Created with AI coding and writing assistance. The included sample cards are original synthetic text, and their abstract art is procedural Canvas geometry from AI-authored code, without a text-to-image model. Screenshots show the real app; the cover uses actual rendered sample cards. Deckshift makes no AI API calls and does not generate AI content for users.
