The Gender Genie is about pasting a text in a box on The Gender Genie. Choose a genre and click submit for the results. It will predict whether the text is written by a man or a woman. I tried it, you can see the result in the picture above this post.
There is even a video on FoxNews about this software
The Gender Genie uses a simplified version of an algorithm developed by Moshe Koppel, Bar-Ilan University in Israel, and Shlomo Argamon, Illinois Institute of Technology, to predict the gender of an author.
Although I think you really can't figure out whether a writer is male or female based on writing, I still believe that the linguists' algorithm has useful applications. I have received emails from several authors saying that they have used it to help make their female characters come across as being more female and vice versa. Now, Customer Experience Crossroads sees it as another tool for tailoring marketing to target market: "We don't all communicate in the same way. Worth considering when you think about customer experience."
