WordAI understands concepts and ideas – if you have ever spun something with WordAI, you’d know that it takes quite some time. That is because before the content spinner even starts doing its thing, it will first read the entire text in order to understand it in both a general and a specific way. That is what allows the software to create much better sentence and paragraph spins, which in turn generates much more unique versions of the content for you to use.
Google is getting VERY good at catching spun content so you'd better be talented at manual spins. If they DO catch you, of course they'll spank you... and hard. So anything you use spun content on is inherently AT RISK. Worse yet... Google gets better at finding spun/poor content every year. So in the longrun you're screwed. I'd weight your other options and see if you couldn't find a cheaper source for manually hand written content.
It’s just okay. Maybe I expected too much but it did not save me much time at all with all the changes I had to make to the articles. I used it on the “readable” setting and allowed it to automatically spin paragraphs, sentences, etc. Well it was actually “readable” but not human readable, also there is option for human readable articles, but it will be not 100% unique.
It looks like the creators of Spin Rewriter 9 .0 have really put a lot of work into creating a piece of software that creates readable content. However, Google isn’t stupid and there are a lot of things that can go wrong when you are trying to “manipulate” Google into giving you more traffic. Google hates spam, badly written content and duplicate content. These are all things that Spin Rewriter 9 .0 is capable of creating. You simply can’t trust a piece of software to write content for you in my opinion.
