What Is LanguageTool?
LanguageTool is an AI-powered grammar, style, and spell checker supporting many languages, with a genuinely usable free plan covering core features and Premium pricing running €19.90/month, dropping to €13.30/month quarterly, €4.90/month annually, or €4.16/month on a 2-year plan (roughly $4.99-$6.99/month equivalents in USD reporting). Team subscriptions for up to 20 users are available at €56.90/user/year.
Its genuinely strong multi-language support is a meaningful differentiator from English-focused grammar checkers like Grammarly specifically — LanguageTool supports dozens of languages with grammar and style checking, which matters for multilingual writers or teams working across several languages rather than just English. Students, teachers, and professors get up to 20% off Premium with a qualifying educational discount.
It's aimed at multilingual writers and teams wanting AI-powered grammar and style checking beyond English-only tools, with the substantial pricing difference between monthly (€19.90) and 2-year billing (€4.16/month effective) making longer commitments dramatically more cost-effective for regular users. See our Writing & Chat tools directory for related tools like Grammarly.
