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.

    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 Sep 26, 2021, 3:13 AM (14 months ago)

      Sorry, forgot the LibreOffice version:
      - LibreOffice 7.2.1.2

    i think this is a virus cause edge did not let me download it saying it can harm my computer.i unistalled while trying to update it and after my computer works smoothly.so i dont nees anymore this addon

    At first, I couldn't get it to work at all. I didn't get any error message whatsoever (such as: wrong Java, wrong LibreOffice version, problem installing LT etc). Installing a different version of Java didn't help. After removing and re-installing LT, I was able to make it work.

    The absolute best

    Does not work on Libreoffice 7.1 with
    OpenJDK Runtime Environment (build 11.0.10+9-suse-1.2-x8664)

  • Qaz Cetelic Feb 10, 2021, 9:06 PM (22 months ago)

    Did not work even after installing java from Java.com instead of using OpenJDK

  • Hugo Oosterkamp Feb 3, 2021, 2:05 PM (22 months ago)

    So far, so good.
    I did install JAVA from java.com and had no further issues. Guess the main issue is the use of openJDK versus Java.com

    OpenSuse TW, LT 5.2.2,

    EN: It seems to be working alright, but just as Javier Rondon said, the only working version for LO 7.0+ is 4.1.

    I tried the latest LanguageTool (5.2.2), and even though I can install it just fine, the service cannot start inside LO, it gives me a "LanguageTool can not start" message popup.

    Hopefully, the next LO update will work with it, otherwise, I hope it can be fixed on LT's side.

    ES: Parece funcionar bien, pero como ya lo dijo Javier Rondon, la única versión que funciona para LO 7.0+ es la 4.1.

    Intenté con la última versión de LanguageTool (5.2.2), y aunque la pude instalar sin problemas, la extensión como tal no funciona en LO, me da como mensaje de error "LanguageTool can not start".

    Espero que la próxima actualización de LO funcione con LT, y si no, espero que se pueda arreglar en el lado de LT.
