Looking at both spinner’s spun articles, they both seem to generate spun content that looks pretty good. Both have some grammar issues I would correct if I was posting it on a high tier 1 site, but overall SpinnerChief produced better content. Not sure if WordAi is being overly aggressive on the spins at the cost of quality. This test is very hard to call. If you go by raw numbers, SpinnerChief won. I want to leave this up to you to decide which one won. Winner none – draw!
When you integrate Perfect Tense with WordAi, Perfect Tense will check any text you spin for grammatical errors. Perfect Tense will then add those spelling and grammatical errors as synonyms. This means that your spintax will be more unique and more readable. When using Perfect Tense with WordAi, your spun content will often end up even higher quality than the original.
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.
Rewriting your article by hand is the classic approach that is slowly dissolving, however, many people still prefer so. Write manually and then rephrasing to ensure the finest quality is the safest way but it can often hours, days or weeks to finish a writing task that can otherwise take only a little time. And that’s why there also exist people who like to save the trouble and their time, so they look for an article rewriter or article spinner to do the job.
Although the idea of quickly being able to create content might sound fantastic, it certainly has its disadvantages. Firstly, Google don’t like badly written content. In the past article spinners have been renown for creating poor quality content. Badly written articles are something that Google hates and you won’t make any human friends with it either.
