LanguageTool

LanguageTool is an AI-based software that checks text for errors in grammar, spelling, punctuation, and style. The system functions across more than 30 languages and dialects, including English, German, and Spanish. It operates through browser add-ons for Chrome, Firefox, and Edge, as well as direct integrations with applications like Google Docs, Microsoft Word, LibreOffice, and various email clients. Core functionalities include a paraphrasing tool, a personal dictionary for custom terminology, and a "Picky Mode" for more stringent analysis. For business and development use, the tool provides a proofreading API and GDPR-compliant solutions for enterprise environments. The software is utilized by professionals in corporate communications, journalism, and marketing, as well as by individual writers and academics. A primary use case involves a communications team employing the Google Docs or Microsoft Word integration to proofread official documents and press releases for grammatical accuracy and stylistic consistency before publication. Another common workflow involves multilingual content creators or customer support agents using the browser extension to check emails, support tickets, and web content in real-time, ensuring clear and error-free communication across different platforms and languages.
