He probably means a plug-in that will enable him to copy someone else's content and the plug-in will automatically rewrite the content to make it unique. For example replacing "Content rewriting" with "Copying someone else's content and spinning it"
Content rewriter plugins have one problem.. THe output is like the writing of a 3rd grader. The words used are synonyms, and many times, they aren't suitable for the sentenance. In one word, there are many.. but it would very easy for a human to detect that .
No that's not my intention, my purpose is just to multiply "My Original Content" three times for my other 3 blogs with the same niche. That's the real reason why I want to have a rewriter plugin.
you can use this plugin , but by this you will loose reps in google with in few months , because this plugin only chnge words not grammer. so be aware before using it.
I think it is better or writing different content on different blogs. Cause google hate duplicate content.
