What is LanguageTool?

LanguageTool checks grammar, spelling, punctuation and style as you write, in more than 30 languages. It works in Chrome, Edge, Firefox and Opera, in Google Docs, Word, Apple Pages and LibreOffice, in email apps such as Gmail and Apple Mail, and as apps for macOS, Windows and iOS. The free plan checks shorter texts and includes a few AI rephrasings a day; Premium raises the length limit and adds unlimited rephrasing.
