I would say that with the exception of the first sentence in the quotes, the content generated by the “Standard” spinner of WordAI is phenomenal. I mean, I have delved into the depths of machine learning and human language data and I know a thing or two about trying to educate a machine on human language. So the results here can be thought of as written by someone who has started learning English a few months ago, but still manages to write understandable human readable content. That is all in my opinion.

SpinnerChief is designed to generate unique articles to provide content for websites and increase site traffic. It does this by spinning one article into multiple versions of itself, replacing certain words, phrases, and sentences with alternate versions of themselves. SpinnerChief can identify parts of speech, correct grammar errors, and use intelligent auto-replace methods until the article is both human-readable and passes Copyscape (a plagiarism checker). The SpinnerChief API allows developers to access SpinnerChief's functions from within other programs and can spin articles in 27 different languages.
Think of it this way: What do you have more chance of hitting, a distant, tiny target or the broad side of a barn? For the sake of search engine optimization, you want your website to be the broad side of barn. The more quality articles, or unique readable content, your website or blog offers to search engines (and therefore the general public) the more exposure your website will receive from major search engines.

It has helped me to get high quality content fast without having to outsource the spins. I used to spend hundreds a month just on getting article spins for all my client sites and SEO campaigns. It's very effective on getting amazing spun variations of highly relevant and high quality content quickly. You can also go back and use them again in the future since it archives them. I love that. (TIP) Spin 10 completely different titles with your articles for ultimate diversity!
The content above is 98% unique according to Spin Rewriter and I really like it. It actually seems better than the WordAI spin – only the “Standard” one however, it is no match for the “Turing”. One thing that the spinner failed to recognize is the “green eyes” phrase where it replaced it with “environment-friendly”. Yea, I laughed too. Anyway, here is the spintax for those interested in more testing:

Very Readable Content – for this one they recommend setting the 1st input to “Very Readable” and allowing both sentence rewriting and paragraph editing (2nd and 3rd input), but disallowing automatic paragraph spinning (the 4th input). Keep in mind that this type of spinning will generate much less unique versions of your content as less synonyms will be used for the words.
I've ranked websites in the past with spun content, and now they are still on #1 position of google. First year (2014) google found me because my spun was really bad, many paragraphs were just copied and my position drop from #2 to around #20 after a panda update. Later I cleaned all my text with better spun (I didn't buy any article!), my ranking went up again, and with more backlinks I reached #1 and it is still there
