Malmoi: Korean Vocabulary

Learn 11,027 TOPIK words with FSRS spaced repetition and AI example sentences. Words from your textbook or K-dramas become custom cards, with AI filling in the meaning.

말모이 Malmoi is a vocabulary app for TOPIK test takers and Korean learners. It covers 11,027 high-frequency Korean words from TOPIK levels 1 to 6 and uses the FSRS spaced repetition algorithm, so you remember more words in less time.

"말모이" was the name of the 1910s project, led by the Korean Language Society, to compile the first Korean dictionary. It literally means "gathering words together."

KEY FEATURES

◆ Everything in English Word meanings, example translations, explanations and AI answers are all in English, and an English voice reads the meanings aloud in autoplay.

◆ FSRS smart scheduling Each card's next review is scheduled from your own memory curve. The better you know a word, the longer the gap, so your time goes to the words you are about to forget.
