It’s designed for everyone who writes—from students polishing a thesis to professionals drafting critical emails—ensuring your message is always communicated with confidence and accuracy.
Key Features
✍️ Comprehensive Correction Go beyond simple typos. LanguageTool meticulously checks your text for complex grammar errors, punctuation mistakes, and stylistic inconsistencies. It even helps you refine your writing by flagging overused words, improper tone, and incorrect casing, ensuring a professional finish.
🌐 Extensive Multilingual Support Write confidently in over 30 languages and dialects. LanguageTool automatically detects the language you're using and applies the correct set of grammatical rules. It supports major languages like English (with six regional variants), Spanish, German, French, and Portuguese, making it an indispensable tool for multilingual communicators.
🔄 AI-Powered Paraphrasing Tool Find the perfect words effortlessly. If a sentence doesn't feel right, the integrated AI paraphraser helps you rewrite it. You can instantly make your text simpler, more formal, fluent, or concise, adapting your tone to any audience or context.
🔌 Seamless Integrations Everywhere Get real-time suggestions wherever you write. LanguageTool integrates directly into your workflow with browser add-ons for Chrome, Firefox, and Safari, as well as dedicated desktop apps for Windows and macOS. It also works within your favorite applications, including Google Docs, Microsoft Word, Outlook, and more.
Why Choose LanguageTool?
LanguageTool offers distinct advantages over other common writing tools by focusing on comprehensive, accessible, and multilingual support.
