Incidentally, just as a piece of quick feedback for clara.io: Registering for a service is really expensive! I have to come up with a password, then file it in my password manager, hand out my email address to some unknown stranger, etc, etc. Mostly I won't bother unless there's some compelling reason to do so; when present with a registration form I'll usually just give up. Since you have a browser-based product, having 'Try now!' button that starts it (with no backend storage!) and let me play with it would make me way more likely to actually sign up.
