I have come to know that there are various auto-content developing tools in the market, but I never tried them once even. Can you please tell me if they're credible and have the tendency to create, non-plagiarized and accurate content what you really want?
There are scads of threads about content generators in this forum. The consensus is that writing your own, original content is best.
Like Linda has said, there's a plethora of threads that answer your question. A search on "Article spinning" should give you the relevant information.
