I disagree partially. I like the idea of a simple way to get a barebones schema, and although I'd probably rather use a simplistic GUI than text, it's not bad.

My bigger problem is that the website feels unprofessional in a way that if I found it off a random google search I'd probably not come back:

1. Part of the website is a screenshot of text rather than actual text for seemingly no reason?

2. The examples aren't raw text and include HTML list elements which makes copy and pasting them awkward.

3. The rest of the website really needs to be run through a grammar checker and proofread.

4. The output of the tool is hard to read and poorly formatted.
