Choose your starting point
- Hangul: the 19 modern consonants and 21 vowels, with romanization notes.
- Hiragana and Katakana: basic kana, voiced forms, combinations, and additional reading marks and sounds.
- Simplified Chinese: standard characters with pinyin and source glosses where available, with an HSK recognition path starting at level 1.
Due reviews come before new characters. Missed characters return in an end review, and free practice lets you explore without changing your review schedule or statistics. The searchable library, daily goals, review forecast, and activity history help you choose what to study next.
