Read full description

AI Spy turns any photo into a spot-the-difference puzzle. HOW IT WORKS Snap a photo or pick one from your library. In seconds, AI Spy creates a subtly modified version of your image using machine learning — changing colors, removing objects, warping shapes, and editing shadows in ways that feel natural, not fake. Your job: find all the differences before time runs out. WHAT MAKES IT DIFFERENT Unlike traditional spot-the-difference games, every puzzle is unique. AI Spy analyzes your actual photos using on-device AI models to generate realistic modifications tailored to the scene — a mug changes color, a plant disappears from a shelf, a shadow shifts just slightly. No two puzzles are ever the same. FEATURES • Generate unlimited puzzles from your own photos • Multiple difficulty levels: Easy, Medium, and Hard • Timer and scoring system — race against the clock • Progressive hint system when you're stuck • Share your results with friends Perfect for puzzle lovers, photography fans, and anyone who wants to train their eye for detail.
