Overview
LanguageTool checks grammar, spelling, punctuation, casing, and style, and it also paraphrases sentences. It is built for people who write in multiple languages and need suggestions for emails, documents, blog posts, essays, and other text.
The tool offers browser add-ons, email add-ons, office plugins, and desktop apps for macOS and Windows. It also includes a writing editor, personal dictionary, text statistics, and a privacy note for the browser add-on that says no text is stored.
LanguageTool supports more than 30 languages and includes a proofreading API for developers and businesses. The project started in 2003 as an open-source project and later became a service used by millions of users.
