LanguageTool is a free and open-source grammar checker, and all its features are available for download[4]. LanguageTool website connects to a commercial sister project LanguageTool Plus, which provides improved error detection for English and German, as well as easier revision of longer texts, following the commercial open-source model. LanguageTool was started by Daniel Naber for his diploma thesis[5] in 2003 (then written in Python), it now supports 31 languages.[6] 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. However, it is massive and requires considerable processing power and I/O speed. As such, LanguageTool is also offered as a freemium web service. This web service can be used via a web interface in a web browser, or via a specialized client-side plug-ins for Microsoft Office[7], LibreOffice[8], Apache OpenOffice,[9] Vim,[10][11] Emacs,[12] Firefox[13], Thunderbird,[14], and Google Chrome[15]. Its web app client can also be integrated on websites.[16]
