LanguageTool is a style and grammar proofreading software for English, French, German, Polish, Dutch, Romanian, and a lot of other languages.

Description

LanguageTool is a style and grammar proofreading software for English, French, German, and many other languages. You can think of LanguageTool as a software to detect errors that a simple spell checker cannot detect, e.g. mixing up there/their, no/now etc. It can also detect some grammar mistakes.

Supported languages are: Asturian, Belarusian, Breton, Catalan, Chinese, Danish, Dutch, English, Esperanto, French, Galician, German, Greek, Italian, Japanese, Khmer, Persian, Polish, Portuguese, Romanian, Russian, Slovak, Slovenian, Spanish, Swedish, Tagalog, Tamil, Ukrainian. Please note that the level of support differs a lot between languages.

NOTE: Starting with LibreOffice 7.4, LanguageTool can be used from LibreOffice without this add-on. However, there are some reasons to use the extension:

  • The extension runs on the local machine. No remote server is needed.
  • The extension supports all rules working on the level of full text (e.g., opening and closing quotes are recognized even if they are more than one paragraph away from each other).
  • The extension automatically adds all lists of correctly spelled words (according to LanguageTool) to the dictionaries used by LibreOffice.
  • The extension supports grammar checking of Impress and Calc documents (Only manual checking by the LT check dialog. An automated check is not supported by LibreOffice.)
  • The extension offers a configuration dialog:
    • Easily activate / deactivate optional rules
    • Easily deactivate / reactivate default rules
    • Define custom colors and styles for rule groups or single rules
    • Change parameters for some special rules
    • Define profiles to check different kinds of documents

If you have trouble with the installation, please see our checklist.

You can always get the latest version of this add-on at https://languagetool.org/download/LanguageTool-stable.oxt - the version linked here at extensions.libreoffice.org might not be up-to-date.

    I have installed it into LibreOffice 7.3 (flatpak version). But the LT toolbar is completely unresponsive, including the "Options" button

  • Peter T Jan 23, 2022, 6:39 PM (16 months ago)

    LT does not work for me at all. Neither the buttons nor the LanguageTool menu items respond in any way.

    Windows 10
    LibreOffice 7.1.8.1 x64
    AdoptOpenJDK 11.0.10
    LanguageTool 5.6

    Specially registered to write a review. Many people write that the extension doesn't work. Everything works fine, I checked it in 7 and 6 offices, but there is a problem of incompatibility with apprmor. The profiles used by the apparmor are not working by default.
    The solution for Ubuntu 20 is as follows:
    sudo apparmor_status | grep libre
    if you see any output here, then you need to delete the Libreoffice profiles for apparmor.

    sudo apparmor_parser -R /etc/apparmor.d/usr.lib.libreoffice.program.*

    Further, if you wish, you can delete files with profiles:
    sudo rm /etc/apparmor.d/usr.lib.libreoffice.program.*


    Специально зарегистрировался чтобы написать отзыв. Многие люди пишут, что расширение не работает. Все прекрасно работает я проверил в 7 и 6 офисе, но есть проблема не совместимости с apparmor. Профили которые использует apparmor не рабочие по умолчанию.

    Решение для Ubuntu 20 следующее:
    sudo apparmor_status | grep libre
    если здесь увидите какой-то вывод, то надо удалить профили Libreoffice для apparmor.

    sudo apparmor_parser -R /etc/apparmor.d/usr.lib.libreoffice.program.*

    Далее по желанию можете удалить файлы с профилями:
    sudo rm /etc/apparmor.d/usr.lib.libreoffice.program.*

      Hi Viktor,
      thank you very much for the posting. Could you post the line how to enable the profile again, if I don't want to use the extension. Is switching off apparmor for libreoffice not a security risk?

    The LT plugin is actually not working at all. LT appears in the menus, but clicking on the icons or the menu commands does not lead to any effect. I'm using LO 7.2.2.2 with LT 5.5.1 on Fedora Linux 35 (64-bit) with Gnome 41.1. The installed Java is standard OpenJDK 11.0.13.
    Clicking on LT options while LO runs in the terminal, the following code appears:
    java.lang.NoClassDefFoundError: Could not initialize class com.sun.java.swing.plaf.gtk.GTKLookAndFeel

    Probably this will help to identify the problem.

    In a previous post I stated I could never get this to work without random crashes of Writer. The problem seems to be solved when you install for all users. All remains very stable now. Now I can give it 5 stars!! Brilliant at what it does.

  • MENGHOK CHENG Nov 1, 2021, 8:12 AM (19 months ago)

    This is another best, foreign language writing tool, Khmer Spell Checker out there beside SBBIC and it could spell khmer language just well!
    Thank you LT

    Since LanguageTool version 5.1.3 the update mechanism via Extension Manager does not work for me anymore. It might happen that other users are also stuck with this version now.
    (LibreOffice 7.1.6.2 x64, Windows 10)

  • Robert Ferraro Oct 24, 2021, 10:43 AM (19 months ago)

    I would love to use this product which seems great BUT I have a large document of 400,000 words and every build I have tried to use would result in Writer crashing to desktop after 1 to 5 minutes. No warnings or errors - just instant closing of Writer. Memory use goes to around 3 to 4 Gb during the checking of the document and then the crash occurs. Windows 10 64 with 32 Gb RAM. Would also crash in Win 7 64.

    I use LanguageTool v 5.4
