Since version 7.4 of LibreOffice, the grammar and style checker by LanguageTool can also be accessed internally. Compared to using this internal access, the extension offers the following advantages:
-
The application runs on the local computer. Therefore, no remote server is required (the use of a remote server, including the LanguageTool Premium service, is still supported).
-
All rules that work at the full-text level are also supported across paragraph boundaries (e.g., opening and closing quotation marks are recognized even if they are more than one paragraph apart).
-
In addition to LibreOffice's spell checker, LanguageTool's is also used.
-
A proprietary caching mechanism is used, which significantly speeds up repeated work on long texts (checking unchanged texts does not have to be repeated, which is time-consuming. After loading a text that has already been checked once, all errors found are displayed almost immediately).
-
A separate WritingTool check dialog is used, which is very performant (it has been optimized for WritingTool's internal caching mechanisms).
-
Manual grammar and style checking of Impress and Calc documents using the WritingTool check dialog is supported.
-
Using a configuration dialog, users can make the following settings, for example:
-
Easily activate or deactivate optional rules
-
Easily deactivate or reactivate default rules
-
Define custom colors and styles for rule groups or individual rules
-
Change parameters for some special rules
-
Define profiles for checking different document types
-
The extension offers the possibility of statistical analyses, such as frequently used words, filler words, etc. (currently only for some languages).
