The instant article spinner or paraphrasing tool carefully scans the article you enter, looking for all the words that it can replace with synonyms. All the words or phrases that will be replaced are colorfully highlighted to make them prominent and easy to identify. By clicking on each of the highlighted text, you can see the original word along with other suggestions, and you also have an option to add your own word. To restore the original text, just click the original word.
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.
