Koharu
ML-powered manga translator, written in Rust.
Koharu introduces a local-first workflow for manga translation, utilizing the power of ML to automate the process. It combines the capabilities of object detection, OCR, inpainting, and LLMs to create a seamless translation experience.
Under the hood, Koharu uses candle and llama.cpp for high-performance inference, with Tauri for the desktop app. All components are written in Rust, ensuring safety and speed.
[!NOTE] Koharu runs its vision models and LLMs locally on your machine to keep your data private and secure.
[!NOTE] Support and discussion are available on the Discord server.
