Very Fast Results - The main benefit that you can get with the tool is that you will be able to get very fast results when it comes to your rewrites. Its a well known fact that this product has been updated over time to the point where it can rewrite a 500 word article into something thats new and unique to the eyes of potential viewers within 9 seconds or less compared to the past version where it will take 2 minutes to finish rewriting.
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.
