I am looking for a free Content Rewrite script or Software. The function of the tools should be automatically rephrase my original text and produce a new contents.
check http://www.contentrewrite.net it is the only one which is contextual at least from what I have seen, others specially those commercials just blindly replace synonyms
I've tried a lot of those programs, and none are going to work flawlessly, most of the time the content comes out making no sense. One way to do it ( I use a software for this, but its unavailable to the public yet) is an article spinner. So you'll write a sentence like "The {dog | cat | horse | frog | } is {big | sick | small | gay}" and it will "spin" the article and make 50 variations. Sort of like a madlib. I'm sure someone with some coding knowledge could write this for themselves easily. Autoblogger also has a rewrite engine, but it just replaces "keyword" with anything you want. For example if you have an rss fed site about playstation 3 and your keyword is "ps3".. you could make every instance of "playstation 3" and change it to "ps3", in every article you specify. And then take "ps3" and set a linking rule to link it to whatever website for backlinks.
Visit some "Freelance" sites, hire a freelance writer and get your articles rephrased. It won't be too costly.
