All you need to do is enter a few paragraphs of your own writing, and let the site analyze it, spitting out the name of your supposed literary kin.
Here's the scoop from the Associated Press:
I Write Like Erupts Online, Authors Scratch Heads
NEW YORK — For anyone who has ever thought Charles Dickens was lurking inside his or her prose, a new website claims it can find your inner author.
The recently launched I Write Like has one simple gimmick: You paste a few paragraphs that exemplify your writing, then click "analyze" and — poof! — you get a badge telling you that you write like Stephen King or Ernest Hemingway or Chuck Palahniuk.
The site's traffic has soared in recent days and its arrival has lit up the blogosphere. Gawker tried a transcript from one of the leaked Mel Gibson phone calls. The suggested author: Margaret Atwood.
The New Yorker found that an invitation to a birthday party was James Joycean. Many others were aghast to discover they wrote similarly to "The Da Vinci Code" scribe Dan Brown.
The New York Times tried putting in actual novels, such as "Moby-Dick." Herman Melville, it turns out, writes less like himself than King, according to I Write Like.
Atwood, herself, tried the site only to discover she also apparently writes like King. "Who knew?" she tweeted.
Eager to try out this kooky new tool, I copied and pasted a few paragraphs from one of three books I've been working on and presto! It turns out I write like Stephenie Meyer. Hmn, curious, since there isn't a vamp or a werewolf in the entire thing!
