It was started by Daniel Naber for his diploma thesis[5] in 2003 (then written in Python). It now supports 31 languages, each developed by volunteer maintainers, usually native speakers of each language.[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. Some languages use 'n-gram' data,[7] 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,[8] LibreOffice,[9] Apache OpenOffice,[10] Vim,[11][12] Emacs,[13][14] Firefox,[15] Thunderbird,[16] and Google Chrome.[17] Its web app client can also be integrated on websites.[18]
