Cost – WordAi Turing at the time of this writing is a monthly charge of $49.95, while SpinnerChief III Ultimate is a one time purchase of $177 or $67 a year. But it’s not entire black and white to add insult to injury WordAi has a usage cap on the how many word you can spin per billing cycle. Here is an excerpt form their page “250,000 words for the “Turing Spinner” for a billing cycle you will be charged overage fees.”. So if you go over that amount WordAi will bill you extra. Spinner Chief Ultimate does not have any usage limitations when using the desktop client. Hands down SpinnerChief III Ultimate won this.

Has a 250,000 words monthly limit on the “Turing Spinner” and a 2,500,000 words monthly limit on the “Standard Spinner”. Anything above that will be charged additionally ($10 per 1,000,000 words for the “Standard Spinner”, and $3 per 10,000 for the “Turing Spinner”). However, they do offer custom plans for heavy API users – all you need to do is contact them.
Don't you hate it when your synonyms make no {sense|perception}? Don't settle for the "content garbage" that most spinners vomit out. WordAi can tell subtle differences between words and makes sure each synonym it picks makes complete sense. This gives you articles that are automatically readable, without you needing to spend countless hours fixing them up!
