LanguageTool is a style and grammar checker that currently supports English, Polish, German, French, Dutch, and other languages to a different degree. It scans the words and their part-of-speech tags for occurrences of error patterns, which are defined in an XML file. More powerful error rules can be written in Java. LanguageTool should be used after the spelling of a text has been corrected.

Changes:
Many updates for the error detection rules for English, Spanish, French, German, Portuguese, Russian, Breton, Catalan, Esperanto, and Ukrainian have been added. The embedded HTTP server can now be started from the context menu if LanguageTool is running in the system tray. Some small bugs have been fixed
