About
LanguageTool is an AI-based writing assistant that checks grammar, spelling, punctuation, casing, and style in more than 30 languages and dialects. It solves a common problem for anyone writing on a computer: catching typos, grammatical mistakes, and awkward phrasing before a text is sent, published, or submitted.
Users can paste text into the web-based editor or install add-ons and desktop apps so that corrections appear while they type. The service detects the language automatically and offers suggestions inline, underlining spelling errors in red and flagging grammar, punctuation, and style issues. A paraphrasing tool rewrites sentences on demand, and a paid Premium tier adds unlimited paraphrasing along with more detailed checks. LanguageTool also provides business offerings described as GDPR-compliant, and its site lists more than 2,000 organizations among its users, including the European Union, Spiegel Magazine, Deutsche Presse-Agentur, Bertelsmann Stiftung, and JetBrains.
