## What is OK JLPT?

OK JLPT helps you prepare for the Japanese-Language Proficiency Test with practice tests. Practice full tests by level and year, keep every mistake in one place, and understand it with clear explanations, notes from other learners, and an AI tutor you can ask follow-up questions.

PRACTICE TESTS & MOCK EXAMS
• Every level from N5 to N1, organized by year
• Vocabulary, grammar, reading and listening
• Take a full timed paper, then see your estimated score and report
• Save a whole test to your phone and do it offline; listening keeps playing with the screen locked or in another app

MISTAKE REVIEW & TARGETED PRACTICE
• Wrong answers are saved automatically, with your answer shown next to the correct one
• Every question comes with an explanation and example sentence
• Practice one part at a time from Papers: pick vocabulary, grammar, reading or listening, then a paper
• Mistakes come back when they are due for review
• Export your mistakes as an Anki deck, or as a PDF mistake book to print and mark up

STUDY NOTES
• See how other learners remember each question: memory tricks, common traps and solving tips
• Add your own notes and help others avoid the same mistakes

ASK THE AI TUTOR
• Still confused after the explanation? Ask Rika, your AI Japanese TA
• Ask why an option is wrong, request another example, or get a new practice question on the same point
• AI answers can be wrong — check them against the explanation

VOCABULARY & GRAMMAR
• Core N5–N1 words in short stages, with pictures and natural audio: sort out the ones you know, then a four-choice check
• Grammar in topic stages, each lesson an explanation, examples and one question
• Every word and grammar point links to the past-paper questions that tested it
• Quick practice: particles, verb forms and numbers, plus a score estimate

STUDY PLAN
• Exam countdown, daily tasks, streaks and an activity heatmap, so you always know what to do next

SYNC ACROSS DEVICES
• Use one account on iPhone and iPad; progress, mistakes and purchases stay in sync
• Sign in with Apple or Google

FREE & PAID
• N5 and N4 practice tests, listening and question-type drills are free
• One free paper for each of N3, N2 and N1
• Monthly Pass (1 month) / Exam Season Pass (6 months): unlock all N3–N1 practice tests and question-type drills. Non-renewing — they never auto-renew
• Lifetime Pass: one purchase, all N3–N1 practice tests and question-type drills unlocked for good
• AI questions are used per question and sold separately as packs; passes do not include AI questions
• Invite friends: when your first 2 new sign-ups enter your invite code, you get 1 month of membership (once per account)

The app's interface is available in English, Simplified Chinese and Traditional Chinese.
