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.

    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.

    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.

    An update: as per the "our checklist" above, having a Mac I installed Java for OS X as suggested there (https://languagetooler.freshdesk.com/en/support/solutions/articles/44002037684-mac-specfic-issues), but only version 5.3 works without error messages.

    • D 5 oct. 2021 à 15:09 (Il y a 3 année)

      Update from myself. Unfortunately the error messages continue also with version 5.3

    Can confirm what’s been said so far.
    With
    - MacOS Big Sur 11.4
    - Oracle JDK 12.0.2
    the last working Language Tool Version is 4.x.

    With 5.x, LT just sits there in the menu. You can click on anything you like and it doesn’t do a thing. No error messages, no nothing.

    • J. Martin 26 sept. 2021 à 03:13 (Il y a 3 année)

      Sorry, forgot the LibreOffice version:
      - LibreOffice 7.2.1.2
