A lightweight, fully modular companion bot for Karuta card collection players. Features 11 powerful modules across 4 categories — 100% free, zero vote locks, and effortlessly configured with an interactive Discord dashboard.
Built from the ground up to respect players and server administrators alike.
No voting locks, no paywalled features, and no premium subscription tiers. Server admins and collectors get unlimited access to all 11 modules and 50-slot personal wishlists from day one.
Every feature is an isolated module. Turn on only the tools your community needs — from drop timers to high-speed OCR scanning — without unwanted clutter or channel spam.
No complicated syntax or command parameters. Run /config to launch an interactive Discord dashboard with category menus, toggle dropdowns, setup modals, and bulk actions.
Each module is independently toggleable per server via the interactive /config dashboard.
