Questions

  1. Can I check a draft without the source text?

    Unnatural phrasing and cultural red flags can be checked without the source. Possible mistranslation is more accurate when you add the source text.

  2. Which languages are supported?

    The first version supports Thai, Indonesian, Filipino and Portuguese.

  3. How do I get the output?

    Review it on screen and copy the text, or save it as a PDF from your browser's print function.

  4. How many free checks do I get?

    The free plan gives you 1 check a day. For more, use the paid plan (¥3,980/month, up to 5 a day).
