How it works

  1. Pick the language you want to write in — English, Japanese, Chinese or Korean.
  2. Write a short piece about whatever you want to say — no topic is assigned, and it does not need to be long.
  3. You get a score and a natural rewrite, with each change explained one at a time.

Common questions

Does it only mark what is wrong?

No. It shows how a native speaker would have written it, and when something is grammatical but still reads oddly it says why.

Is it fine to write only a little?

Two or three sentences is plenty. What matters is that the phrasing you actually reach for shows up, not the length.
