The privacy-first, multilingual grammar and style checker — 30+ languages, and you can self-host it.
LanguageTool is the grammar checker for people who are not writing in English — or who care about privacy. It supports 30+ languages, flags style and tone issues (not just typos), and offers a self-hosted enterprise edition. The free tier is solid; Premium adds paraphrasing and advanced style.
Who it's for: Multilingual writers, Europeans, privacy-conscious teams, and developers who want to self-host a checker.
One checker for English, German, Spanish, French, and more.
Flags wordiness, informal tone, and inconsistent style.
Option to process text without saving it.
Enterprise edition runs fully on your infrastructure.
If you write in more than one language, or you care about privacy, LanguageTool beats Grammarly outright. English-only writers who want the slickest experience may still prefer Grammarly — but LanguageTool is the more open, more honest choice.
