If you have not used a spinner before then I would suggest that you first use something that require more human imput like The Best Spinner or Spinner Chief in order to understand the basic principles. However if you must go fully auto then I would suggest you go for Wicked Article Creator. I have it and understand it is similar to wordAI but a one off fee of $47.
This time, WordAI calculates the spin it generated at 97% uniqueness which is basically completely unique. If you look at the text above, again, the first sentence of the quoted content is a bit confusing, but the rest is still good. I would even say that the last sentence came out better than the previous spin, but generally, yes, the above spin looks more like a human wrote it.
