WordFreak's functionality can be easily extend via a its plugin architecture. The plugin architecture allows WordFreak to support additional annotation tasks, visualization components, file formats, and automatic annotators.

You can add a plugin to WordFreak by simply adding a jar to your class-path. When launched, WordFreak examines jars in your class-path for instances of classes which implement org.annotation.wordfreak.Plugin and populates its menus appropiately. For help developing WordFreak plugins, see the Plugin Development Overview in WordFreak's interactive help.

Some plugins that we have developed for WordFreak that may be of wider use are described here. Their source code is available in the WordFreak CVS repository under plugins.
