  • Long text in one go

    Free 3,000 characters, Basic 4,000, Premium 7,000 per check.

  • Choose the checker

    Use the Naver or Daum (Kakao) spelling checker. If one fails, the app retries once with the other.

  • History

    Originals and corrections are kept on your device so you can look back.

  • Daily Korean quiz

    More than 100 tricky spelling questions, each with an explanation.

Privacy

  • Text you check is sent only to the Naver or Daum (Kakao) spelling checker. It is not sent to our servers.
  • Your check history stays on your device.
  • Only when you tap “Why is it wrong?”, the corrected word and error type go through our server (Google Firebase) to Google Vertex AI (Gemini). Surrounding sentences are not sent.
  • The app includes ads (Google AdMob with mediation partner Liftoff), usage statistics (Google Analytics) and remote config and notifications (Firebase).
  • To count daily AI explanations, the app creates an anonymous identifier (Firebase anonymous account). It is not linked to a name, email or phone number.
