## What is Seidoku AI?

Seidoku AI turns your camera into a Japanese OCR, romaji, pronunciation, and translation assistant.

Take a photo of any Japanese text — textbooks, signs, menus, or notes — and Seidoku AI instantly recognizes it with high accuracy, reads it aloud in natural native pronunciation, and provides a translation. Built especially for learners who want to read along and improve as they go.

KEY FEATURES

- AI-Powered OCR — Advanced AI recognition delivers exceptionally high accuracy
- Furigana Removal — Automatically filters out the furigana printed above kanji, extracting only clean Japanese text
- Romaji Reading — Shows the yomigana of every word in romaji, so you always know how to pronounce it
- Native Pronunciation — Listen to clear, natural text-to-speech for every sentence
- Instant Translation — Understand what you're reading right away
- Edit & Refine — Adjust recognized text for perfect accuracy
- Simple & Fast — No login, no account, no clutter. Just open and read

WHY SEIDOKU AI?

Many textbooks print furigana above or beside the kanji, which confuses ordinary OCR tools. Seidoku AI intelligently removes this noise and extracts only the Japanese text you need — then gives you the romaji reading so you can read it with confidence, every time.

WHO IS IT FOR?

Seidoku AI is designed for learners of Japanese who study with physical textbooks and want a faster, more accurate way to look up, hear, and understand kanji. Whether you're a beginner mastering hiragana and katakana or an intermediate learner reading native materials, Seidoku AI helps you read with confidence.
