I really like Katteb. I bought it about a year and a half ago and use it often even though I have probably 6 writing tools that are somewhat similar. They have a few seldom seen unique features that others do not. My favorite thing is the URL writer. Basically, you throw in the url of a website and you can write something from that information. So, if you need copy for a web page, you can plunk in a website url and it will spit out some decent web copy that is different, but similar to what is on the page you put in. It is great for getting a head start on copy for a website.

I also use the article re-writer a lot. If there is something good. I throw it in there and get a decent duplicate. I can then revise from there or throw it in the humanizer.

The cons? I would love to be able to have a box where I could steer the article with a prompt. So if I got Katteb to rewrite something, it would be nice to ask it to "use this company name" or to "make it 3rd person" to revise it further, but I would rarely need that.

All in all, I love it. I use it a lot. The youtube to article is also great.
