Frequently Asked Questions (FAQ)

Q. Is Wordtune free to use?

Yes. The free Basic plan offers 10 rewrites/AI suggestions per day, 3 summarizations per month, and unlimited spell and grammar checking. For higher usage, upgrade to the Advanced or Unlimited paid plan.

Q. Is Japanese supported?

Wordtune is specialized in English rewriting, summarization, and writing assistance, and is not practically suited to Japanese proofreading or rewriting. It has limited support for non-English languages as a translation source, but Japanese is not listed as a supported source language. For Japanese text, pairing it with a Japanese-capable tool like DeepL is the practical approach.

Q. How does Wordtune differ from Grammarly?

Grammarly excels at correcting English grammar and spelling, while Wordtune's strength is rewriting and paraphrasing — expressing the same idea in a different way. If you mainly want error correction, Grammarly is the better fit; if you want to broaden your range of expression, Wordtune is the right choice.

Q. What environments can I use it in?

Installing the browser extension lets you use it directly in Gmail, Google Docs, and other web services. You can also work within the Wordtune editor.
