Prompt Ninja is a word-based image generator that instantly returns one of 4,000 unique pixelated ninjas. Type any word and get a consistent ninja every time, thanks to a custom hashing algorithm that locks each word to a specific design.
Behind the scenes, it runs on a Python script using the Pillow library, transforming 16 hand-crafted base designs into thousands of colorful variants. The system is lean, fast, and deterministic — no loading, no randomness.
Building Prompt Ninja taught the fundamentals of hashing, batch image generation, and designing interactive tools with visual feedback — all with zero prior web dev experience.
