Koharu

Koharu is a free, open-source manga translation application that combines machine learning with visual editing tools. It automates text detection, optical character recognition, translation, and artwork restoration. Users can import manga pages from images, archives, and PDF documents. Its translation pipeline supports local language models and compatible hosted AI providers. Generative inpainting removes original text while reconstructing the surrounding artwork. A WebGPU-powered canvas allows manual cleanup, proofreading, and translated text placement. Multilingual text rendering supports vertical Japanese and Chinese layouts, right-to-left scripts, and automatic font fitting. Additional capabilities include layered PSD export, GPU acceleration, and agent-based project automation.
