★ 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.

I liked the automatic language recognition but the fact that for French it couldn't recognise the difference between transitive and intransitive verbs with its basic version was odd. I understand companies need to make money, but I was hoping for something a little more. Other than that for what it does do it does it very well.

It gives less worthy suggestions than Google Doc's automatic grammar checker

This feels more natural than Grammarly and it is even more helpful.

Helpful when it comes to skimming over small mistakes and helps me recognize more problems in my writing! Recommended for people checking for small mistakes, I would not rely completely on this app but it's pretty reliable.

good but didn't improve the beginning of my sentences and did not uppercase it. Everything else is good.

I like how it doesn't have a premium package or whatever, where you can access the whole thing if you buy it. I also like how it has the suggestions and stuff.
