AI Manga Translation—Fast, Accurate, Multilingual OCR | AI Manga Translate

What is AI Manga Translate?

AI Manga Translate is an advanced online tool that uses artificial intelligence and optical character recognition (OCR) technology to provide fast, accurate, and multilingual translations of manga and doujin content. The platform specializes in handling both vertical and horizontal text layouts while preserving the original visual integrity of the material.

How Does AI Manga Translate Work?

The system combines multiple AI technologies in a seamless workflow:

OCR Processing: The tool first scans uploaded images or PDFs using specialized OCR models (mOCR recommended or legacy 48px option) to detect and extract text from speech bubbles and captions.

AI Translation Engine: Extracted text is processed through various language models including offline auto-selection, OpenAI's ChatGPT, SugoiCT2 (specialized for Japanese↔English), NLLB, M2M100, mBART-50, Qwen2, and others. Users can switch between models to match specific language pairs and translation styles.

Layout Preservation: The system automatically detects text direction (vertical/horizontal) and applies intelligent typesetting that maintains original font sizes, line spacing, and bubble areas to ensure visual fidelity.

Batch Processing: Supports parallel processing of multiple pages and entire PDF documents, automatically merging results while preserving page dimensions and reading order.
