Stay away from content boss, its not what it claims and defintely not going to create unique content that will pass duplicate comparisons. I put 4 different articles of my own creation through it's system. At best it created an article that was 60% a duplicate of the first. The worst version was 70% duplicated. Sure it creates sentances that read half decently, but it's still duplicate material. At 60% you might as well rewrite it yourself. I dont mind some some tweaking and rewriting after wrangling/spinning an article I half expected to, but if the program can only spit out 60% duplicated material, that in the end doesn't save you an ounce of time, since your going to have to rewrite it anyways.. Plus the content assistant, doesn't work, it only returns unrelated crap. The program also doesn't offer any refunds so even at 24 bucks, stay away, stay far away.
No intention to offend anybody but I think there are many junk article spinner software for junk sites.
