It's a wordmeter. A tool that lets you see how often you use certain words in your writing. My three main characters are Max, Julia and Sebastian and the chapter I uploaded is entitled Balthazar. I can see how this will be really useful. We all have a tendency to repeat certain words. With this tool you can see just how often that word comes up.
Tabitha, thanks again! Also, this is the guy that created it. Thanks, dude!
