Overview
★ Finds many errors that Google's spell checker cannot detect
★ No registration needed
★ Supports more than 25 languages (see below)

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, German, Spanish, French, Dutch, Polish, and Russian.

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 mistakes that native speakers commonly make and it will improve your writing overall. 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. 

Usage: Just click "Add-ons > LanguageTool > Check text" in the menu to start proofreading your document. The detected errors will be shown on the sidebar. Select an error and it will be highlighted in the text.

Unlike Grammarly and Ginger, LanguageTool works for many languages.

It's a great checker but is a bit stubborn and a bit rude. It catches things that was meant to be there like quotations, and double spacing at a beginning of sentences. And it wanted me to change my last NAME! So overall I'd recommended still but be careful with it because one wrong and rude fix, can get on your nerve like that.
