Only standard WordAI spinner showed 12% match for me in Copyscape which is very good I think. Also I will add that for SPAM links in general you don’t need any quality at all. if Google crawler can’t find connection with other spinned articles – goal achieved. Sorry, but I don’t see that with expensive spinners as Copyspace shows that in plain sight.
SpinnerChief 5 has super-advanced functions such as auto-grammar fix, for example it will correct "a apple" to "an apple," plus it can spin "I want to eat the apple, orange and banana" to "I want to eat the banana, orange and apple." We can't list all functions here, there are too many to list! - But one thing is sure, SpinnerChief 5 will give you the best rewritten article - no other spinner can do what SpinnerChief 5 does!
Notice: Because of the 3 days free trial, we must use Paypal's subscription button even for a one-time price. Unfortunately Paypal has a bug that only allows you to set max 5 years for the subscription. So when you see Paypal's notice that your one-time fee is actually a subscription that will be renewed in 5 years, in fact it is not true, it is a one-time forever payment, NOT renewable after 5 years.
These days there are a lot of article rewriting softwares and it is pretty hard to choose one that will suit all your needs (quality + price – no subscription at least). When you will look for example at WordAI article spinner – you will notice that there is pretty expensive subscription (50 dollars per month) while spinnerchief costs only 77 dollars per year (which is about $6.5 per month).
Other article spinners also require that you enter your own custom synonyms manually or individually approve lists of potential synonyms as they are presented to you. This is another way of expecting you to do most of thinking, as opposed to expecting the software to be smart enough to instantly make judgment calls for you. Thus, one of Spinbot's main goals is to make the article spinning process as quick and painless as possible.
