Some suggestions:

The landing page has an information overload (at least for me). I have a hard time understanding what to look at, because it's both a landing page with very dense writings, and at the same time something that looks like a real app.

Less is more. Look at some of the best landing pages out there. They tell the core story with a few words. A video where you walk through your product is even better.

Thats fair! Its trying to be a landing page and the actual app at the same time, so you cant really tell where to look. Because of yout feedback just pushed a change, cut most of the wall of text and moved the live demo up so its right under the headline instead of buried at the bottom. A short walkthrough clip is next on the list.

Thanks for taking the time to write it out, genuinly useful!
