LanguageTool

LanguageTool is an AI-based grammar, spelling, and style checker that supports over 30 languages and dialects. It helps users improve their writing by detecting errors in grammar, punctuation, spelling, casing, and style, and offers suggestions for improvement. The tool also includes a paraphrasing feature that uses artificial intelligence to rephrase sentences to be more formal, fluent, simple, or concise. LanguageTool is available as a browser add-on for Chrome, Firefox, Edge, Safari, and Opera, and integrates with office suites like Google Docs, Microsoft Word, Apple Pages, and LibreOffice. It also offers desktop apps for macOS and Windows, and email add-ons for Gmail, Apple Mail, Outlook, and Thunderbird. The free version corrects spelling, simple punctuation, and some style mistakes, while the Premium version unlocks all error detection and additional features like unlimited paraphrasing and the Picky Mode, which provides more style and tonality suggestions. LanguageTool is used by over 2000 organizations including BMW Group, European Union, and Spiegel Magazine. It provides a distraction-free editor with personal dictionary, statistics tracking, and secure text storage.
