A real N5 question. The wrong-answer feedback is the part that matters.
昨日、友達と映画を＿＿＿。
Yesterday, I ___ a movie with a friend.
What you get
Speedrun, not study session
10 questions, ~3 minutes. Repeat in the cracks of your day. Sessions are short on purpose — the metric is mastery per active minute, not hours logged.
Process-level wrong-answer feedback
Every distractor has its own rationale. You learn why the wrong answer was wrong, not just that it was. That’s how misconceptions get corrected, not papered over.
Weak-review that finds you
Items you got wrong yesterday surface again today, automatically. No manual flashcard curation. The conversion (wrong → right) is the only thing the system cares about.
Five levels. 13,664 questions.
Simple pricing
