What exactly is Jazzy? Well, for developers, it is a set of APIs (Application Programming Interfaces) that allow you to add spell checking functionality to Java Applications easily. For end-users, Jazzy does not do too much besides spell check things you paste into an applet. Eventually, I plan to create an applet that would be suitable for use in HTML forms that will allow the user to spell check a html textarea before submitting.
