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 are some 'free' article spinners out there that require you to enter your text with properly formatted 'spintax' in order to create the end result. But how you need a totally separate tool to create this machine formatted text, so how is this really useful to you? Spinbot does all thinking for you, from taking in the context of every phrase to creating additional textual content that is as readable and meaningful as the text you originally entered.
