Tips

1

Run a final check before sending important emails or official documents.

2

Register your team's prohibited word list as custom NG words for consistent proofreading.

3

Ra-nuki words are common in spoken Japanese but should be avoided in business writing.

FAQ

  • Q1

    What is double-keigo?

    Double-keigo is the excessive stacking of polite forms, e.g. 'おっしゃられる'. It should be simplified to correct keigo.

  • Q2

    Can all NG expressions be detected?

    Built-in rules cover representative cases, but not all. Human review is still needed for final approval.

  • Q3

    Are custom NG words saved?

    Custom NG words reset when the page is closed. Save your list externally if you want to reuse it.
