Rose shared this on Twitter, and I had fun playing with it too:
https://iwl.me/ You paste some of your writing into the box, and it will analyze your writing style and word choice to see which famous writer you write like.
It says to post at least a few paragraphs, but I recommend posting a full chapter of a story because it seems to be more consistent that way. I tried it with several stories, and when I was just posting a few paragraphs, I got a different result almost every time - Stephen King, Margaret Atwood, Cory Doctorow, Stephen King again, and Agatha Christie. When I switched to posting full chapters, I got Agatha Christie every time, regardless of what kind of story I was posting. I think that's funny because she is best known for mysteries, and I'm terrible at writing mysteries, but hey, I'll take it!
Post your results here after you've tried it!
