Stay in Japan Project: JLPT

A JLPT study app built for people living, working, or studying in Japan.

■ Content
· 7,710 vocabulary words, graded N5–N1
· 382 grammar points with examples and plain-language explanations
· JLPT drill zone: kanji, vocabulary and grammar, explained question by
question, with question banks for every level from N5 to N1
· Verb conjugation practice, practical sentence patterns, listening and reading
· Mock exams for each level

■ AI practice (new)
· AI scenario conversations: pick a situation and start talking — convenience
store, izakaya, restaurant, train station, apartment hunting, job interviews
and more. Stuck for the Japanese? Type in Chinese or English and the app
converts it to Japanese for you, keeping your original text alongside it.
Kanji in the AI's replies come with furigana, and tapping any character
shows its reading and meaning.
· AI speaking practice: say a Japanese line out loud and find out right away
whether your pronunciation landed.

■ How you study
· SRS spaced repetition decides what to review and when, so you don't have to
· Wrong-answer review: after each drill, walk back through every question —
what you picked, what the answer is, and why
· Daily reminders at a time you choose, to build the habit
· Study history and streaks, so you can see your own progress

■ Sync across devices
The phone app and the desktop site share one account, synced in real time.
Study vocabulary and drills on your commute, sit a mock exam at home.

■ Pricing
Most features are free. Premium removes the daily limits on SRS, drills, AI
conversation, speaking, verb practice and mock exams. Monthly, annual and
one-time purchase options are available.

■ About
Built by a front-end engineer working in Japan, originally to pass their own
N2 — now shared with everyone else preparing for the JLPT.

■ New this autumn
· YouTube shadowing: paste a Japanese video and follow, shadow, dictate and quiz one line at a time (27 curated videos included)
· Listening "JLPT mode": Japanese-only question and options, read aloud after the passage; meaning shown after you answer
· Flashcards show the example sentence with native audio; AI shadowing scores you line by line
· Referral codes: enter a friend's or creator's code for 10% off annual and lifetime plans in-app
· Progress (daily goal, drill records) syncs instantly between phone and computer
