What it solves

This application addresses the challenge of reading foreign-language manga on Android devices by automating the translation process. It detects text bubbles within images, performs optical character recognition (OCR), and uses AI to translate the text directly over the original artwork.

How it works

The app uses a local detection model to identify speech bubbles and text blocks. It then performs OCR—either locally or via an OpenAI-compatible API—to extract the text. An LLM (Large Language Model) translates the extracted text, which is then displayed in draggable, customizable bubbles overlaid on the original image. It also features a floating window mode for real-time translation of any content on your screen.

Who it’s for

It is designed for manga readers who want to consume content in languages they are not fluent in without leaving their Android device. It is particularly useful for users who prefer a local, managed library experience or need a quick way to translate text while browsing other apps.
