Hey Product Hunt, I'm Vinicius, a collector and a developer. This started with my four-year-old daughter. She wanted in on the hobby, and at card shows she obviously couldn't read set symbols or collector numbers, but she could match pictures. So I started printing the cards I was still missing at real card size and slotting them into the binder pages. She'd go around the show with me, compare it to what was on the tables, binder, and having genuinely found things before I realize. She was helping, and very engaged. That turned out to solve my problem too. A binder page with three empty pockets looks unfinished for months while you hunt the last card, and the printed ones hold their place until the real card turns up. The gaps stop being gaps and become a want list easy to slot. Pokébinder is that, as a tool. Search English or Japanese cards, drag them into 3×3 pages, and run your own artwork behind a whole page with the cards sitting on top (the Michi-method pages you've seen on Instagram). Mark what you don't own, and it prints exactly those at 6.3 × 8.8 cm, nine to an A4 or Letter sheet, with cut guides. They're binder placeholders, not proxies for play. It's free, there's no account and no ads, and your binder is saved in your own browser rather than on my server. Other tools print a fixed catalogue of placeholders; this prints the binder you actually built, and only the cards you're missing. I'd love to know how the print sizing lands on your printer, and what you'd want for a full master-set build. I'm here all day.
