Content at Scale
Ten traits get measured: average sentence length, variance in that length, vocabulary range, contraction rate, em-dash habit, semicolon habit, question frequency, average word length, common-word share and repeated sentence openers.
Individually these are trivia. Together they are a fingerprint stable enough to write against, and specific enough that a rewrite aimed at them comes back sounding like you rather than like a style guide.
This is also the most useful thing here for writers who are not worried about detectors at all. If you are trying to keep a consistent voice across a team, or work out why one piece reads flat next to another, the trait comparison between two samples answers it in numbers.
FAQ
A fingerprint of your writing habits across ten measured traits, built from samples you paste in. It lives in your browser's local storage, never on a server, and rewrites target its numbers instead of a generic human average.
150 words is the floor. Several hundred across two or three pieces is much better, and mixing registers, an email, an essay, something informal, gives a fingerprint that holds up on more kinds of draft.
Technically yes, and it is a good way to study a writer you admire. Passing off their fingerprint as yours is a different matter, and worth thinking about before you do it.
The writing analysis and your Style DNA run in your browser. For a real AI score, the text you check is sent to an AI-detection provider, and we never store it. When you rewrite on a paid plan, the draft is sent to our server, rewritten and sent back without being stored. AI features (rewriting, humanizing and Copilot) send the text to Cloudflare Workers AI, which processes it and doesn't keep it.
