Which Famous Author Do You Write Like?

How the test decides which author you write like

Every writer leaves a fingerprint in the mechanics of their prose, and the fingerprint has almost nothing to do with subject matter. The test reads twelve of those mechanics from your text: how many words you put in a sentence, how long your words are, how often you reach for a comma or a semicolon, how much of your text is dialogue, how many -ly adverbs you allow, how often "and" joins your clauses, how many sentences are questions or exclamations, the share of very short and very long words, and how often you say "I". Each of the 30 authors has a profile on the same twelve measures, built from their best-known books, and your text is scored by its distance from each profile. The closest five are shown, with the percentages telling you how much nearer the first is than the rest.

This is a simplified form of stylometry, the method used to show that Robert Galbraith was J.K. Rowling in 2013 and to argue over which Federalist Papers Madison wrote. The serious versions use hundreds of function-word frequencies; this one uses twelve habits you can actually see and change. That makes it less precise and more useful: when it says you write like Hemingway, the fingerprint panel shows you exactly why (14 words a sentence, almost no semicolons, half your sentences in dialogue), and you can decide whether that is what you want.

Worked example

A 400-word blog post with 24 sentences (16.7 words each), 4.3 letters a word, 5 commas and 0.2 semicolons per 100 words, no dialogue, 1.1 adverbs per 100 words and 6 uses of "I" per 100 words lands between Margaret Atwood and Haruki Murakami: short, first-person, lightly punctuated, no speech. Turn the same post into a story with quoted conversation and it moves to Raymond Chandler. Join the sentences with semicolons and lengthen them to 28 words and it drifts toward Virginia Woolf. The author is a label for a region of the table; the numbers are the thing worth reading.

The 30 authors and what pulls you toward each

Profiles are approximate fingerprints of each author's typical published prose, rounded for display. They describe habits, not quality, and translated authors are measured through their standard English translations.

What the result does not tell you

Whether the writing is good. Vocabulary beyond word length. Structure above the sentence: paragraphing, pacing, where the information sits. And it cannot see voice, which is why two people with identical fingerprints can read nothing alike. Treat the match as a mirror for your habits: if every sample you paste comes back Agatha Christie, your sentences are short and your paragraphs are talk, and you now know which dials to turn if you want something else. Pasting three different pieces (an email, a story, a report) and getting three different authors is the normal and healthy result; getting the same author every time means you have one register.

Using it as an editing tool

Writers use the fingerprint panel more than the author name. If a draft is meant to be brisk and comes back at 27 words a sentence with 9 commas per 100 words, the fix is in the numbers: split sentences, cut the subordinate clauses. If a story has 5% dialogue and the author matches are all essayists, the characters are not talking enough. The readability checker on this site gives the grade level for the same text, and the sentence counter lists the longest sentences to split first. For a school assignment, the useful comparison is your own text before and after an edit, not the author label.
