I get the impression that there is a very good idea here but you are not selling it very well. I think a text-heavy explanation is better here than on the webpage itself.

People on this site don't tend to have much patience when being shown something new. It would be great if you could dive right in as a guest user somehow. The CTAs on the webpage are not very inviting also imo. Not many people are going to want to sign up just to try something novel.
