Landing-page would have been a great opportunity to show the effects of the tool in action. Have a casual-text (a slightly longer version of what is stated there now) that explains it at the top and display different versions (utilizing different fonts) that use other lingo (i.e.: business, student, techies) at the bottom to show what the tool is actually doing. Add a prominent link to the examples, to show the actual tool in action, and I'm sold.

Or to phrase it another way: Shit needs more bling!
