Unlike other spinners, WordAi fully understands what each word content means. It doesn’t view sentences as just a list of words, it views them as real things that interact with each other. This human like understanding allows WordAI to automatically rewrite entire sentences from scratch. This high level of rewriting ensures that Google and Copyscape can’t detect your content while still remaining human readable!
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
