Common questions

Is LanguageTool better than Outwrite for non-English writers?

Yes. LanguageTool supports over 30 languages, while Outwrite only supports English, French, and Spanish. If you write in German, Dutch, or Portuguese, LanguageTool is the clear winner.

Which tool is easier to get started with?

Outwrite is slightly easier — just install the browser extension and it works. LanguageTool requires creating an account and installing an add-on, but it's still straightforward for most people.

Can I use these tools on my phone?

Neither tool has a dedicated mobile app. However, LanguageTool's browser extension works on mobile browsers like Safari, and Outwrite's extension works on Chrome mobile. Neither is ideal for phone use.

Which tool is better for improving writing style?

Outwrite is better for style and sentence structure. Its paraphrasing tool and style suggestions are more advanced than LanguageTool's, which focuses more on basic grammar and spelling.

Is the free version of either tool worth using?

LanguageTool's free version is more useful — it catches basic spelling and grammar mistakes in many languages. Outwrite's free tier is very limited and will push you to upgrade quickly.

Which tool is more private?

LanguageTool is more private. You can self-host it on your own server, and it's GDPR-compliant. Outwrite is cloud-only, so your text is processed on their servers.

LanguageTool wins for multilingual users and privacy; Outwrite wins for English style and paraphrasing.

If you write in multiple languages or care about privacy, go with LanguageTool — it's free, powerful, and respects your data. If you're an English writer who wants to polish your sentences and don't mind paying a few bucks a month, Outwrite is a solid choice. Both are worth trying for free first.
