## What it is
KanaDojo is a free, aesthetic, minimalist web platform for learning Japanese hiragana, katakana, kanji, and vocabulary, inspired by Duolingo and Monkeytype. It is built with Next.js, TypeScript, and Zustand, using spaced repetition and gamified training modes with data from JMdict and KANJIDIC.

## Use cases
- learn hiragana and katakana online
- study kanji by JLPT level
- practice japanese vocabulary with spaced repetition
- free duolingo alternative for japanese
- memorize kana with typing drills
- convert word lists to anki decks
- learn japanese writing system for beginners

## When to choose
- you want a free, browser-based tool to master kana, kanji, and JLPT vocabulary
- you prefer minimalist, Monkeytype-style typing drills over gamified mobile apps
- you want an open-source project with beginner-friendly contribution opportunities

## When to avoid
