LanguageTool is a free and open-source grammar checker, and all its features are available for download.[3] LanguageTool website connects to a proprietary sister project LanguageTool Plus, which provides improved error detection for English and German, as well as easier revision of longer texts, following the open-core model.
It was started by Daniel Naber for his diploma thesis[4] in 2003 (then written in Python). It now supports 31 languages, each developed by volunteer maintainers, usually native speakers of each language.[5] Based on error detection patterns, rules are created and then tested for a given text.
The core app itself is free and open-source, and can be downloaded for offline use. Some languages use 'n-gram' data,[6] which is massive and requires considerable processing power and I/O speed, for some extra detections. As such, LanguageTool is also offered as a web service that does the processing of 'n-grams' data on the server side. LanguageTool Plus also uses n-grams as part of its freemium business model.
LanguageTool web service can be used via a web interface in a web browser, or via a specialized client-side plug-ins for Microsoft Office, LibreOffice, Apache OpenOffice, Vim, Emacs, Firefox, Thunderbird, and Google Chrome. Its web app client can also be integrated on websites.[7]
