CatDex is a Discord collection game where you discover and collect real cats from photographs. Use /cat add to submit a cat photo and build your personal collection through deterministic rarity tiers, visual traits, favorites, statistics, and collectible Cat Cards.
CatDex can detect cats in submitted images, guide you through photos containing multiple cats, and help prevent duplicate discoveries. You can browse and filter your collection, inspect individual cats, track your rarity progress, and safely delete entries whenever needed.
CatDex uses image analysis to identify visual traits, while game rarity is determined exclusively by transparent in-app rules—not assigned by AI.
