Features
Most JLPT apps tell you right or wrong. Raisu explains every option — every time.
2 minutes. 5 questions. Built around your weakest areas. No two days the same.
Miss something? It comes back from a different angle until it clicks. Smarter every session.
Why the right answer is right AND why each wrong one is wrong. Every question teaches.
One number. How prepared are you? Watch it climb. Know exactly what's holding you back.
"Grammar is at 43% — focus on te-form." Real advice from real performance data.
Streaks, smart reminders, and a system designed for learners who've quit other apps.
Concept Revisit
Got something wrong? Raisu remembers. The same concept resurfaces from a different angle — a different question type — until you truly understand it. Not just memorize "it was option C."
AI Coach
"You're mixing up ichidan and godan patterns." Specific guidance based on your actual quiz results. Updated after every session. Not generic textbook tips.
Personalized
Raisu analyzes your weak spots and builds each daily quiz around them. You see exactly which areas it's targeting — and why. No generic question dumps.
Every question teaches you why. The app gets smarter every time you practice. And it costs nothing.

All five: N5 through N1. Every question matches the real JLPT difficulty, kanji usage, and question format for its level.
