You’re reading a Japanese manga and encounter an unfamiliar kanji. Or you’re walking through a Japanese restaurant and see an interesting menu item. Traditionally, you’d have to manually look up each character by radical — a tedious process that kills your momentum.
Not anymore. Kanjijo’s built-in OCR scanner lets you point your camera at any Japanese text and instantly identify every character.
What Is OCR?
Optical Character Recognition (OCR) is technology that reads text from images. Kanjijo uses advanced on-device OCR optimized specifically for Japanese characters — Kanji, Hiragana, and Katakana.
Key point: All OCR processing happens on your device. No images are sent to any server. Your privacy is fully protected.
How It Works in Kanjijo
- Open the scanner: Tap the camera icon in Kanjijo’s search screen
- Point at text: Aim your camera at any Japanese text — books, signs, documents, screens, manga
- Instant recognition: Kanjijo identifies all Japanese characters in the frame within 1 second
- Browse results: See detailed flashcards for every word detected — readings, meanings, and examples
- Save to collection: Tap to save any word to your personal flashcard collection for SRS review
Where to Use OCR for Japanese Learning
- Manga & Light Novels: Scan panels you don’t understand. Build vocabulary from stories you love.
- Textbooks & Worksheets: Quickly look up unknown kanji while studying.
- Menus & Signs: Traveling in Japan? Scan restaurant menus, train station signs, and product labels.
- Business Documents: Working with Japanese texts? Scan and look up specialized vocabulary.
- Handwritten Notes: OCR can even recognize clearly written handwritten Japanese.
Why OCR + SRS = Supercharged Learning
The real power is the combination: scan something interesting → save it → SRS reviews it automatically. This means:
- You learn vocabulary relevant to your life
- Words have personal context (you remember WHERE you scanned them)
- You never lose a new word — SRS ensures long-term retention
Scan Japanese Text: Before vs After
Before OCR: See unknown kanji → Count strokes → Look up radical → Search dictionary → Maybe find it after 5 minutes → Forget to review later.
With Kanjijo OCR: See unknown kanji → Point camera → Instant result → Save to collection → SRS reviews automatically. Total time: 5 seconds.
Built into Kanjijo. No extra apps needed.
