None of the spinning programs I’ve ever heard of have been as effective as you’d want them to be. Trust me, it’s much easier to go in manually and rewrite the original text than get flagged. Some of the stuff I’ve read looked like complete nonsense. If I, as a reader, come across a spun article I immediately catch it and go looking for the original.
Wordai and then a manual edit is probably the best you’d get it. But why would you want to use spun content on your money site?
