Do you mean software that will modify an existing article to help in avoiding a duplicate content penalty?
I use "Instant Article Wizard." It is not free, but it is the only one I know that can create articles that are pretty readable and can pass for real writing. Though you still have to rewrite the article a little.
if you want the same results, go to your favorite search engine and do a search for a term that IAW tells you, but in quotes. You will get back a listing of what you are looking for. Granted this method would take forever, but it's the general idea of how the software works.
i would suggest it doing manual submission. if your going to pay for a software. i not just hire someone to do it manually.
yes, there is a software like this but its not for free, its quite expensive but really worth and can pass google's duplicate content so you can't be penalize for it.
I wont Recommend any soft ware for that purpose. I don't think these can make something totally original. Rather make an investment by getting Articles written by some good content writer
I agree with beacon.seo. Try to do it manually. You are not only practicing to write an article but you will also enhancing your communication skills.
All article writing software is rubbish. Stay well clear of it. If you write your own high quality articles you'll get far more traffic than 100's of manufactured or duplicate articles
unless you find an honest writer, they will most likely be using the same software the op is trying to find.
I think there is no free software which provide good and reason wise article for your sites.. So don't west your time and start writing article. Webmaster
