Master JLPT and TOPIK vocabulary — one app, two languages

PiPi Words is a two-way Japanese-Korean vocabulary app covering JLPT N5-N1 and TOPIK levels 1-6. Learn Japanese vocabulary or Korean vocabulary — both in one place, the way exams actually test them.

■ Vocabulary flashcards built for real exams

JLPT vocabulary and TOPIK vocabulary are organized around actual exam question types. Practice meaning recall, kanji reading and writing, fill-in-the-blank, and dictation — the same formats you'll face on test day.

■ SM-2 spaced repetition so words actually stick

The SM-2 algorithm resurfaces each word right before you'd forget it. No blind repetition — efficient vocabulary building that saves study time.

■ Fully offline, no account required

All study data stays on your device. No sign-up, no internet connection needed — study on a plane, subway, or anywhere else.

■ Track progress like a voyage

See your JLPT and TOPIK level progress at a glance on the voyage map. Daily streaks and achievements build consistent study habits.

■ Listen and learn pronunciation

Hear Japanese and Korean pronunciation with on-device speech. Dictation quizzes sharpen your listening skills at the same time.

■ Free to start, expand when you're ready

JLPT N5 and N4 vocabulary, plus TOPIK levels 1-2, are completely free. Unlock higher levels (N3-N1, TOPIK 3-6) with individual packs or a subscription. Go premium to remove ads and study without limits.
