LanguageTool

LanguageTool is an AI-based grammar checker that checks grammar, punctuation, and spelling errors across over 30 languages. It is designed for users who write emails, blog posts, or social media content, as well as organizations that need writing tools. Key capabilities include a browser add-on that works on Chrome, Firefox, Edge, and Safari, providing suggestions while the user types on any website without storing text. It also offers a dedicated Editor with a distraction-free writing experience, a personal dictionary, statistics to track writing progress, and secure text storage. A “Picky Mode” provides additional suggestions for advanced punctuation, style, and typography. The tool integrates with Microsoft Office and has desktop applications for Windows and macOS. A free tier is available, while LanguageTool Premium offers expanded features. The tool automatically detects the language being used and provides suggestions accordingly. Over 4 million users and organizations such as BMW Group, European Union, and Spiegel Magazine are cited as trusting the tool.
