- LanguageTool online editor
- LanguageTool in Web Browsers
- Install LanguageTool in LibreOffice
- Install LanguageTool in Google Docs
- Install LanguageTool on Thunderbird
LanguageTool is an open-source tool for checking text for spelling and grammar errors. Currently, it supports more than 20 different languages including such less popular languages as Slovenian, Swedish, and Polish.
LanguageTool supports many popular writing applications such as LibreOffice, Microsoft Word, and Google Docs. It also has plugins for Firefox and Google Chrome. Also, there is a plugin for Thunderbird, my favorite email app.
You can also use the online editor which is very useful to check your text only by pasting it on.
LanguageTool online editor
The online editor of LanguageTool is available at languagetool.org
By accessing this address, you will be able to see a box where we can paste your text for spell and grammar checking. You need to choose the language of your text at the bottom panel:
Once you have pasted the text, you will see the errors highlighted. By clicking on any of them, you will be suggested a possible fix. Clicking on it will correct the error.
The online editor is helpful when you work on someone’s computer that doesn’t have LanguageTool installed.

The online editor is a great tool, but having a built-in spelling and grammar is much better. LanguageTool can be installed as an extension in Firefox and Google Chrome to check any writing you do in your browser.

Note: In some Linux distributions such as Arch Linux, LibreOffice comes with LanguageTool built-in , so there is no need to install it.

Once you have installed the plugin, restart Thunderbird. LanguageTool is installed and ready to be tested. To activate the correction, click on the Grammar button. The LanguageTool panel will be displayed at the bottom of the window. All text corrections will be there:
Unfortunately, changes cannot be made automatically in Thunderbird. You have to change the text to correct the errors manually.
LanguageTool is available for many other apps including such popular editors as Emacs and VIM. It is also available for your Android phone.
LanguageTool is a great spelling and grammar checker that is integrated into many text editors. I hope your writing will become much better after you start using.
