Description

IMPORTANT NOTE: The LanguageTool extension is no longer supported. The successor is WritingTool, a writing assistant for LibreOffice, based on LanguageTool (see writingtool.org)

***

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.

    Muy buena extensión, de las mejores, ayuda mucho al hacer correcciones.
    lo único que le haría falta seria un modo oscuro.

    LanguageTool 6.4 is causing me problems with MultiFormatSave extension, so I'm reverting to 6.3.1 for now.

    updating my rating opinion

  • DBg Apr 15, 2024, 11:26 PM (8 months ago)

    ★ ★ ★ ☆ ☆

    My rating is tentative, as I am currently learning / testing the extension, with LibreOffice on windows 10 pro. I am also comparing with web version, and the standalone desktop, to see what how it should work or not with same test given different contexts, so I can keep working with it.

    The LO extension, generated dialog windows are very small UI font size that can't be changed apparently, or it would render the rest of the OS including LO, out of its own ergonomic range (itself a pain to manage across the board of windows OS graphical objects and software type).

    I will revise my rating upon further information, either way. I am liking the things I see in the interfaces on the web and standalone. but I would enjoy being able to do that integrated into LO. (even if I would also like the web/standalone, UI font size to be independent between the UI and the text under review.

    • DBg May 1, 2024, 8:15 PM (8 months ago)

      It seems the integrated version in libre-office works well, as well as withing browser text boxes in MS edge.

      Howevere only the LO extension has a fine grain options to control. The web and standalone seem to behave identical, probably same web technology.

      I am now prefering the extension to the integrated, for its options, however unable to find through google and LT web site a place whether some indications of the meaning of those options might be.
      e.g. section header and choices in:
      Sentence exceeding rules: Text check move?
      Paragraph check mode?

      I think the inline mode contex menu font is readable. but when suing the extension dialog box, it might be java ruling the font size.

    Tiene muchos errores y limitaciones. Era un buen producto pero se ha convertido en un verdadero dolor de cabeza porque marca como error palabras bien escritas como las compuestas como "supermercado" (por "super" y "mercado").

    This has a few quirks, but it won my heart (and this review) by suggesting I use "propose" because I'd used "suggest" in the previous sentence. Very sophisticated for something that's free people. Went to MS 365 and it's bloated with false positives.

    This didn't work because Java wasn't installed on my computer. Go to java.com, download it, the go to Tools>Options>Advanced>[Under Java Options] Add...> C:\Program Files\Java\jre-1.8

    Tip: Hit F7 instead of clicking this extension's icon in the toolbar which is much more sluggish.

    • daddy blondlegs Nov 2, 2023, 2:39 AM (14 months ago)

      Correction: Go to Tools>Spelling instead of F7

    • daddy blondlegs Nov 2, 2023, 1:51 AM (14 months ago)

      Note to devs: the Grammar Rules and Style Rules under Options is unreadably squished

    Müll! LO bleibt ständig damit hängen, Bereiche werden ständig neu geprüft, obwohl sie ignoriert wurden, zu umständlich! Nicht wirklich brauchbar!

    Using LT 5.9 on LO 7.4 under Windows 11. Works well in many respects, but it interferes with autocorrect, specifically "always correct to", which results in blank spaces. Also seems to deactivate itself when the computer comes out of sleep mode. Its spellchecker interferes with LO spellchecker and must be turned off.

  • ROKE BEEDELL Jun 18, 2022, 1:30 PM (3 years ago)

    ★ ★ ★ ☆ ☆

    This extension operates, but part of the interface of it is impossible to observe. Additionally, some of what it corrects is correct, because the dictionary of it is inadequate.
