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.
Spin Rewriter integrates with almost any SEO software. This allows you to post high quality articles quickly and easily. The only drawback is that you only get something like 300 API requests every 24 hours. You can quickly burn through this if you’re doing multiple campaigns. The developer does not currently offer a plan for heavy API users but maybe they will in the future.
