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!

Typing instead of flashcards is an uncommon approach. Do you track whether users actually progress between JLPT levels, or do most stay on one?

Hey, Congrats on the launch :)

I have been learning Japanse on Duolingo before a trip to Japan, this looks like a solid alternative. Is it also for total beginners?

Anyway, upvoted you and I wish you a good launch!

How does the automatic mistake tracking decide when something goes into your review notes, is it every single typo or does it filter for patterns where you consistently misread certain kanji? Looks great!

Hello Hoyoung, Really cute website, I am curious to learn Japanese.

This app is super good!

However, are there any way to learn from super beginner who does not know a,b,c,d,e.... x,y,z?

I don't know alphabets of Japanese.

If you can add the alphabets options for super beginner then it will be more awesome! Still it is awesome work!

Furthermore, I tried to search in Apple's application to download but does it not released in App? It will be more useful if it is used in mobile phone as well.

Keep going! Doing great works!
