About LanguageTool
LanguageTool is a grammar and style checker that works in your browser and inside many writing apps. It supports a large number of languages, including English, German, French and Spanish.
What it does
You paste or type text into the checker, and it highlights grammar mistakes, spelling errors and style suggestions. A paraphrasing tool can reword a sentence, and the checker can adjust tone. Browser add-ons and extensions for email and office apps bring the same checks into the tools you already use every day.
