I personally love this one. It creates amazing content and is extremely affordable. We use a combination of WordAI and Spin Rewriter for our SEO projects, because these two are just an amazing combination. I think Spin Rewriter beats the “Standard Spinner” of WordAI in terms of quality and human readability, but loses to its “Turing Spinner”. So what we do is use the “Turing Spinner” for Tier 1 projects and then Spin Rewriter for the lower tiers. Sometimes we might switch them up, but it really depends a lot on the situation.
There is also the option to spin capitalized words (assumed to be proper nouns) as well as leave any number of words unchanged, depending on whatever you enter into the "ignore" field, separated by commas. You also have the option to only keep the sentences that were altered a minimum percentage, as indicated by the "Keep Sentences that Changed" option.
Start with a quality article. This means a unique topic or viewpoint on a very specific topic. The information must be valuable to a human reader. At this point in time, it is not possible for any software program to produce content that is engaging. If you start out with a low-quality article, the chances are high that the alternate versions are going to be even worse.
