How it works

From first slip to fixed.

  1. Day 1Write

    最近、新しい会社に働き始めた。

    Write about your day, in your own words.

  2. Day 1Accept

    会社に働き始めた会社で働き始めた

    The lab spots the mistake and explains it. You decide if it counts.

  3. The next two weeksInterview

    新しい会社で働き始めた。

    It comes back as a quick question, just before you'd forget it.

  4. Day 15Prove

    駅の近くの会社で働いている。

    Then one day you write it right without thinking. Case closed.

Why it works

Built around the mistakes you actually make.

  • Your mistakes,
    not a textbook's.

    Every lesson comes from something you actually wrote — so it's always one you need.

  • Remembered,
    not repeated.

    Each mistake goes on file. When it shows up again, the lab notices — and so will you.

  • Practice
    that sticks.

    Short, spaced reviews keep it fresh until you can write it on your own.

Questions

Do I need a Japanese keyboard?
No. Type in romaji and it turns into kana as you write.
What level do I need?
If you can write a few simple sentences, you're ready.
