Hey everyone! 👋 I built Douzo because I wanted a simple way to practice reading Japanese by actually typing it — no flashcards, no multiple choice, just reading and typing. The idea is simple: you see a Japanese sentence or word, and you type it in romaji. Over time, your reading speed naturally improves because your brain learns to process Japanese characters faster. Everything is organized by JLPT level (N5–N1), so you can start at your level and work up. Mistakes are automatically saved to review notes, and you can export them to Anki. It's completely free, no account needed, and all data stays in your browser. Would love to hear your feedback — what works, what doesn't, what you'd want added. Thanks for checking it out!
