Koharu is a local-first desktop application that automates manga translation using machine learning, combining text/bubble detection, OCR, LLM-based translation, and generative inpainting in one pipeline. It is written in Rust with a Tauri/WebGPU editor for manual cleanup, typesetting, review, and PNG or layered PSD export.

Use cases

  • translate manga pages from japanese to other languages
  • remove original lettering from comic artwork with inpainting
  • run ocr on manga speech bubbles locally
  • typeset translated text with vertical cjk and rtl support
  • export translated manga as png or layered psd
  • batch translate a whole manga chapter or archive
  • proofread and correct ocr and translation output

When to choose

  • you want a fully local, privacy-preserving manga translation workflow with gpu acceleration
  • you need an end-to-end pipeline from detection to typesetting and export in one app
  • you want editable, reviewable output rather than an opaque one-shot conversion
  • you need layered PSD export for further editing

When to avoid

  • you need a headless server-side batch translation service
  • you have no gpu and need fast inference (cpu fallback is slow)
  • you only need plain text translation without image editing
  • you require platforms beyond windows, linux, or apple-silicon macos
