There is only one article spinner I currently use and recommend and that one is the subject of this article, Spin Rewriter. I have personally been using it for over 5 years and have had great results. The newest version is fantastic. Some people use the newly spun articles as is but I do not recommend that. You should always read your newly spun articles and make corrections plus add some of your own content. This is a tool and you should use it like that. You will have a quality website with unique easy to read content that is very understandable.
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.
