Three real writing samples in. A measurable profile out — ten style metrics with tolerances, plus extracted traits — and every draft is checked against it like a proof against its specimen. Not a vibe. A measurement.
Voice DNA on every plan · the specimen below is our own — measured, not mocked
Plus extracted traits — formality (1–10), directness, humour — from the AI trait pass. Every metric carries a tolerance for the proof check.
Below: one announcement, written twice, both drafts run through the production voice-match scorer against the specimen above. The readouts are its actual output. The generic draft isn’t wrong because it’s ugly — it’s wrong because it’s measurably not this voice.
The monotone is the tell: every sentence the same length.
What surprised us, dogfooding this: our first “punchy” rewrite scored 66 — worse than the generic draft. The measured voice wanted longer, more varied sentences than we’d have guessed. That gap between what you’d guess and what’s measured is the whole point of the instrument.
Readouts: production scorer, actual output · tolerances per metricThe moment a client’s knowledge base exists, a tone profile is generated silently from it — three descriptors, vocabulary, sentence style. No twenty-question onboarding. It’s the default the writing room uses until you cut the full specimen.
Paste three pieces of the client’s real writing — 2,000 words minimum, the same bar we held ourselves to above — and the extractor cuts the full specimen: ten quantitative metrics plus AI-extracted traits. The Writer drafts in it, the Humaniser polishes against it, and the proof check scores every draft.
How the writing room uses it →It means named metrics with tolerances, measured deterministically — the numbers on this page are the instrument’s own. The trait layer (formality, directness, humour) is an AI reading on top, and we say so. No soul-absorption claims.
The profile above is ours, for real — cut from our own published copy by the production extractor, before/after scored by the production matcher. When it surprised us, we printed the surprise.
