Suzanne Lucas tested Articoolo and published her review on INC.
Her main conclusion was this: Articoolo is not able to completely replace human writers but it can definitely help them, especially if you need some SEO ready content.
I can definitely see this as a tool to help a non-writer get going. Running the same keywords through twice gave me two different jumping off points and some things to think about. For $0.99 per article, it’s not a bad deal if you’re willing to do some editing and your focus is on getting content available for search engines.
