Kontent Machine has been designed with one idea only - backlinks. The sheer amount and type of content it produces cannot be found in any other similar piece of software.
This strongly depends on the settings you choose. The more readable the content the less unique it will be.
KM is using a variety of methods - article & title scraping, nested spintax, paragraph mixing, word spinning, HTML character spinning, stop words spinning
All of them. Seriously!
Absolutely (though we do not understand that urge!), KM generates non-spintax output too.
