Before WordAi even starts spinning, it reads the entire article to understand both "generally" what the article is about and the "specifics" as to what exactly happens in the article. This allows WordAi to create complicated paragraph and document level spins based on its deep understanding of the article. Because no other machine has this level of deep understanding, it makes your content look human written. It is even able to correctly write high quality titles by identifying what the article is talking about.
