When I feed it a writing sample from a magical girl RP, where I tend to write about supernatural powers and the occasional lewd moment:

[i]Anne Rice (born Howard Allen Frances O'Brien; October 4, 1941) is a best-selling American author of metaphysical gothic fiction, Christian literature and erotica[/i]

When I feed it the opening post to the Danganronpa RP I GM, which is a murder mystery/court story for those unfamiliar.

[i]Dame Agatha Mary Clarissa Christie DBE (née Miller; 15 September 1890 – 12 January 1976) was a British crime writer of novels, short stories, and plays. She also wrote romances under the name Mary Westmacott, but she is best remembered for her 66 detective novels and more than 15 short story collections (especially those featuring Hercule Poirot or Miss Jane Marple), and her successful West End plays.[/i]

When I feed it a part of a post in which a character reflects on their grim situation. 

[i]Kurt Vonnegut, Jr. (November 11, 1922 – April 11, 2007) was a 20th century American writer. His works such as Cat's Cradle (1963), Slaughterhouse-Five (1969), and Breakfast of Champions (1973) blend satire, gallows humor, and science fiction.[/i]

The "I write like" thing states that it "analyzes your word choice and writing style and compares them with those of the famous writers." But I feel like it looks at the wrong words. Using the word "murder" doesn't necessarily mean I write like Dame, just that my sample is likely about the genre she covered.

Still a fun toy to play around with. It's always interesting to try and figure out how these things work. I'm kind of curious if others had the same results as me.
