The app processes comic images through multiple stages: text detection using deep learning models, OCR for character recognition, inpainting to remove original text, and LLM-based translation via GPT-4. It supports various input formats including images, PDF, EPUB, CBR, and CBZ comic archives. Users can translate to and from languages including English, Korean, Japanese, French, Chinese, Russian, German, Dutch, Spanish, and Italian. The project is built with Python, PyQt6, and PyTorch.
