Kotoba Sensei - AI Japanese furigana generator & reading tool

Hey everyone 👋 I built Kotoba Sensei because I’ve always struggled with reading native Japanese — even after years of study, furigana tools often got the readings wrong, especially for dates, names, and idioms. It broke the flow of learning. So I decided to fix that. Kotoba Sensei uses AI fine-tuned for context — it doesn’t just look up dictionary entries; it understands how words are used. You can paste any Japanese text (or even upload an image like a manga panel), and instantly get accurate furigana, translations, and natural TTS audio — all in one clean interface. Compared to existing tools, Kotoba Sensei: 💡 Handles tricky readings like 八日 → ようか correctly 📷 Works on images (OCR via Gemini) 🌍 Translates to English, Chinese, or Korean 🔊 Reads aloud with realistic voices 🧠 Saves your history & favorites for review I’m most proud that it turns Japanese reading into something immersive — you don’t just decode text anymore; you understand it. Would love to hear your feedback — especially if you’re learning Japanese or teaching it! 🙏 Try it here: kotobasensei.com
