Style and Grammar Checking for Chrome

Google Chrome supports spell checking, but even for native speakers it's easy to mix up words ("Children resemble there parents") or to make typos that result in grammar errors ("I talks to him yesterday"). LanguageTool is an Open Source style and grammar checker that detects many of the problems a common spell checker will miss. It's now available as an extension for the Google Chrome browser so you can conveniently check text before you submit it on the web.

It's free, no registration is required, and we don't collect your text data. It supports English, Spanish, French, Russian, German, Polish, and more.

After installation, an icon will show up next to your address bar:

To check a text, click on the extension icon while your cursor is in the text field you'd like to check. A pop up will show the potential errors:

Most errors that LanguageTool can detect come with one or more suggestions to fix the error. Click it to have the error replaced in your text. You can also select text outside of an input area and have it checked. You won't be able to click the suggestions then, as the extension cannot edit static text. The extension's default shortcut is Ctrl+Shift+Space.

Known Issues

There's a small number of sites that the extension won't work on. One of them is Google Docs. If you find another one, please let us know. If your text contains an error but the extension doesn't detect it, that's probably because we don't have an error detection rule for that error yet. Please consider contributing.
