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

See https://languagetoolplus.com/addon-redirect for our browser add-on, which also supports Google Docs.

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.

Your privacy is important to us: By default, this extension will check your text by sending it to https://languagetool.org over a securely encrypted connection. No account is needed to use this extension. We don't store the texts you check. In fact, we don't even store your IP address. See https://languagetool.org/privacy/ for our privacy policy.

List of supported languages: English (Australian, Canadian, GB, New Zealand, South African, US), French, German (Austria, Germany, Swiss), Arabic, Asturian, Belarusian, Breton, Catalan (also Valencian), Chinese, Danish, Dutch, Esperanto, Galician, Greek, Italian, Japanese, Khmer, Persian, Polish, Portuguese (Brazil, Portugal, Angola, Mozambique), Romanian, Russian, Slovak, Slovenian, Spanish, Swedish, Tagalog, Tamil, Ukrainian

Gonna get at least a 7 in my Spanish essay, thank you a lot! It has a really good interface, it's really simple to use and it's actually correct, I've checked.

I use this to proof my department's comments for students. In general, it is great, it tracks down a ton of errors and gives good advice to fix them. There are two features I'd like to see in the future. One is applying a change across all instances in a document. With many repeated comments, I end up simply having to find/replace on repeated errors instead of just instantly doing it with LT. If a rule can be made to Ignore an error across the document, can't the same rule apply to fixing the same error? The other is an over-analysis of proper names. I would love a setting to filter for them without adding hundreds of unique student names to my personal library.
