My experience;

It takes just as much time to write something original from the ground that it takes to write something (with all variations) that a rewriting software outputs good enough. Don't get me wrong

I would love an answer to this myself, having a huge amount of low-priority blogs that need semi-original content.

But beware, google is evil; if they consider your stuff copies, you'll be hurt. You can't rely on word-switching. ie, cunt-->pussy--twat.
You have to make the outcome of the rewriting-software do better, and that means you have to write the variations yourself. And that takes a lot of time.

But I might be wrong, maybe I do it all wrong
