Hey Product Hunt! I'm Raaghav, and I built Chromanga because I've always wished I could read my favorite manga in color but existing tools required uploading images to a server, which felt slow and sketchy. Chromanga runs the entire AI model inside your browser using ONNX Runtime Web with WebGPU acceleration. Nothing is uploaded. Nothing leaves your machine. It's like having a colorization studio in a browser tab. The first colorization takes a few minutes while the engine warms up (shader compilation & weight loading), but after that it gets progressively faster. Cached results load instantly. Try it out and let me know what you think! I'm here all day to answer questions!
