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

See https://languagetool.org/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.

This was super helpful! Especially for picky mode identifying those run-on's that I accidentally created. However it was unable to recognize that Hurlbut is a last name---honestly I am not surprised since many systems claim my last name is a grammatical error in of itself. However, it was also unable to recognize that Cadence is a proper noun, a name, and should be capitalized. But other than that I love it!

This app is good overall, but it could be better if you had a quick fix button so that we wouldn't waste time trying to pick which one is the best.

Some words like unique last names are detected, but that's understandable. Great plug-in. Definitely better than regular Google spell checker.

super helpful. wish it was more "live corrective" like Grammarly but I love how it gives you options for conjugations for different contexts and meanings. Which Grammarly does for paid members and in English only.
