I'm sorry to hear that you didn't find it useful. Thanks for trying it out though! I'd like to understand better what you're looking for; my email's in my profile if you'd be willing to talk further. If you're using the Word Add-In, the diff runs on your computer. If you're using the online demo on the bottom right of our homepage, it runs on our server.
