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