With this extension you can check text with the free style and grammar checker LanguageTool. LanguageTool finds many errors that a simple spell checker cannot detect, like mixing up there/their, a/an, or repeating a word, and it can detect some grammar problems. It supports more than 25 languages, including English, Spanish, French, German, Polish, and Russian.

LanguageTool is designed with simplicity in mind. It instantly checks the spelling and grammar of any text in the current text field. LanguageTool is compatible with almost all text, regardless of source, including social networks such as Twitter or LinkedIn and online e-mail services, such as Gmail. Very few sites like chrome.google.com currently aren't supported.

With LanguageTool our aim is to give users a fully-featured grammar checker and proofreader that will enable them to have control and confidence over their content. While LanguageTool is a vital extension for non-native speakers, it’s also smart enough to recognize many mistakes that native speakers commonly make. This grammar and spelling correction works across all variations of common language; distinguishing between U.S. and British English, for instance. LanguageTool also features a personal dictionary for exceptions or words that you might commonly use but that are not found in a conventional dictionary. LanguageTool will recognize these words in future grammar checking and proofreading.

LanguageTool works for many languages - unlike Grammarly (a.k.a. Grammerly :-), Ginger, and ProWritingAid.
