한글
Master Korean vocabulary — letter by letter.
A typing-first spaced-repetition system: 50 levels, 2,000 essential words, and feedback that shows you the exact letter you misspelled.
Try a review — no account, no Korean keyboard needed
water
Tap the keys above or type on your own keyboard — the letters land where a real Korean keyboard puts them. Get one wrong on purpose to see the letter-by-letter feedback.
A curriculum, not a word dump
50 levels of 40 words each — 20 vocabulary, 20 verbs — ordered by frequency from survival basics to advanced. Grow a level to 새싹 (Sprout) to unlock the next.
Typing-first reviews
Every word is tested both ways: recognize its meaning, and type it in Korean with your own keyboard. Recognition fades — spelling sticks.
Letter-level feedback
Typed 조아요 instead of 좋아요? HanGeul splits every syllable into its letters and points at the exact one you missed:
You typed
Correct answer
Reviews that space themselves
Answer correctly and a word waits longer before its next review; miss it and it comes back sooner. Words climb five stages until they're burned into memory.
