A proofreading tool for ten languages, including English, German, French, and Polish that checks your spelling, grammar and style.
With this add-in you can review text through our style and grammar checker LanguageTool. LanguageTool finds a lot of errors that a simple spell checker cannot detect, like mixing up there/their, a/an or word repetition, and it can detect many other grammar issues. Currently, we support these languages: English, Spanish, French, German, Polish, Russian, Catalan, Dutch, Portuguese, and Ukrainian
Our grammar and spelling correction works across all variations of common language, for instance distinguishing between U.S. and British English. LanguageTool also features a personal dictionary for exceptions or words that you might commonly use but that are not found in a conventional dictionary.
To use it, just click on the "LT" icon and start proofreading your document. The detected errors will be shown in the sidebar. To make full use of the add-in after a trial period, you will need a paid account at https://languagetool.org.
