Pokébinder

Product Introduction

1. Definition: Pokébinder is a free, browser-based binder planning and placeholder printing tool for Pokémon Trading Card Game (TCG) collectors. It is a Progressive Web Application (PWA) that functions as a digital binder simulator and print utility.
2. Core Value Proposition: It exists to solve the organizational and financial planning challenges of physical Pokémon TCG collecting. The tool allows collectors to visually plan and design complete 3x3 binder pages digitally, experiment with layouts and custom art, and then generate accurate, true-to-size physical placeholder cards to fill gaps in their collection, eliminating guesswork before purchase.

Main Features

1. Comprehensive Card Database & Search: The application integrates with the Pokémon TCG API, providing access to over 40,000 English and Japanese card printings. The search functionality allows filtering by card name, expansion set, and artist (for English cards), enabling precise discovery of specific collector-chase versions and alternate arts.
2. Digital Binder Page Designer: A core technical feature is the interactive 3x3 grid canvas. Users can drag-and-drop (or tap-to-move on mobile) cards into any of the nine pockets. The system supports advanced art layering, allowing a single image to span 2-3 pockets horizontally or vertically, or to act as a full-page background (the "Michi method"). This background image can be zoomed and repositioned dynamically, with the viewport clipping to each pocket for precise visual planning.
3. True-Size Placeholder Generation & Print Engine: For cards marked as "not owned," the application generates a print-ready PDF. It renders placeholder cards at the exact standard Pokémon TCG size of 63mm x 88mm (6.3 x 8.8 cm) at 300 DPI. The print template includes dashed cut guides around each card and intelligently tiles nine cards per standard A4 or US Letter sheet. This feature also correctly slices and aligns any user-uploaded spanning artwork across the designated pockets.

Problems Solved

1. Pain Point: The high cost of trial-and-error in physical binder arranging. Collectors often buy cards only to find they don't fit a planned aesthetic or layout, leading to wasted money and constant reorganization. Pokébinder solves this by enabling free, unlimited digital mockups.
2. Target Audience: The primary user personas are Pokémon TCG Collectors (focused on completionism or art), Binder Artists (those who create themed pages using the Michi method), and Budget-Conscious Hobbyists who want a precise "shopping list" for their collection goals.
3. Use Cases: Essential for planning high-value "master set" binders, designing artistic thematic pages before purchasing component cards, and maintaining an organized, visual record of a large collection's completion status with accurate physical stand-ins.

Unique Advantages

1. Differentiation: Unlike static spreadsheet checklists (like Google Sheets) or generic collection tracker apps, Pokébinder is specifically engineered for spatial binder planning and physical output. It differs from other placeholder generators by deeply integrating the Michi-method art workflow directly into the planning stage, not as a separate step.
2. Key Innovation: Its "digital-first, physical-output" hybrid model. The key technology is the client-side rendering engine that saves the entire binder state (including card positions and custom art transformations) locally in the user's browser (via LocalStorage/IndexedDB), requiring no account, while seamlessly bridging to high-fidelity physical print output. This creates a persistent, private planning workspace.

Frequently Asked Questions (FAQ)

1. Is Pokébinder free to use, and where is my data stored? Yes, Pokébinder is completely free with no accounts, watermarks, or ads. All your binder data, card arrangements, and uploaded images are stored locally in your web browser's storage on your own device; it is not uploaded to any server.
2. What is the difference between a placeholder and a proxy card? A placeholder is an organizational tool printed at true card size to occupy an empty pocket in a collector's binder, visually marking what is missing. It is not intended or designed for gameplay (proxies) or sale, as it uses low-resolution artwork and is clearly a placeholder.
3. Can I use Pokébinder to plan a binder with Japanese Pokémon cards? Absolutely. The database includes over 21,000 Japanese card printings, searchable by name and set. You can mix and match English and Japanese cards on the same 3x3 binder page and generate placeholders for any of them.
4. What paper size and print settings should I use for the best placeholder results? The tool generates PDFs optimized for standard A4 or US Letter (8.5" x 11") paper. For best results, print at "Actual Size" or 100% scale in your PDF viewer, with margins disabled if possible, and use a heavier cardstock (e.g., 160-200 gsm) for a feel similar to a real card sleeve insert.
5. How does the Michi method artwork printing work? When you set an image as a full-page background, Pokébinder's print engine automatically slices it into nine segments, each aligned perfectly within the cut guides of its respective pocket. You print the sheet, cut out each image slice along the dashes, and place them in the binder pockets behind your real cards.
