Writing grammatically correct and stylistically beautiful texts in the browser has now become much more convenient. LanguageTool, known to desktop users of Collabora Office and LibreOffice as a powerful grammar checker extension, is now also available for Collabora Online. In this article you can find out how to use it for your online documents.

About LanguageTool

LanguageTool’s mission is to unleash the professional writing skills in every user. It is an open-source project based on AI-technology that analyses the style, tonality, and typography of text and instantly generates context-aware suggestions. The software supports spell- and grammar checking for 30 languages and is constantly being enhanced by an international team of linguistic professionals and machine learning experts. Besides the plug-ins for desktop office suits, it offers add-ons for all major browsers.

Some Preliminary Comments

Many users of LanguageTool’s browser add-ons may already be familiar with how LanguageTool works. Once installed, it automatically highlights errors in composed online forms and text fields in different colours. However, the documents we edit in Collabora Online are not text in the true sense of the word, as the document never leaves its location on the server. Users only see image renderings of the document during editing. For this reason, a server-side setting must be made to activate LanguageTool. For more information, please consult the technical documentation on LanguageTool. Additionally, a paid premium account with LanguageTool offers better checking results and a larger selection of alternative formulations.

Using LanguageTool in Collabora Online

Through the integration of LanguageTool, different types of errors in text are now highlighted in different colours within Collabora Online. Spelling errors continue being indicated by a red underlining. Grammatical errors are indicated by an orange underline, while stylistic errors are underlined in blue. If you mark the highlighted error, you can display alternative formulations by right-clicking and selecting them through the context menu. LanguageTool’s grammar correction works in all Collabora Online modules, i.e., not only in text documents but also in spreadsheets, presentations, or Draw designs.

Examples of Grammar- and Style Checking with LanguageTool

Here are just a few examples of style and grammar mistakes that LanguageTool can detect.

1. Terms spelled with a hyphen
2. Wrong use of nouns and pronouns
3. Start of sentences in lower case
4. Typographical Mistakes (missing or needless commas, typographical ellipsis character, unpaired parentheses)
5. (Presumably) Incorrect dates and weekday (Weekday and date mismatch, dates in the future)
6. Successive beginning of sentences with the same word
7. Stylistic redundancies (e.g., 6 PM in the afternoon)
