Measured client writing guided a rejected campaign's rebuild

I compared 241 reference pieces and rebuilt the copy against the studio's own voice profile.

My first round of AI-assisted copy sounded like AI, so I measured the client's own copy and wrote a rebuild that landed inside its range.

A rail measures how often verbs are contracted, from "did not" to "didn't". My first round sits at 4 percent. Measuring 241 pieces of the client's copy lights a band from 59 to about 94 percent, and in a first measurement, a rebuild written fresh to those numbers lands at 87 percent, inside it.

Case Studies

Context

The client couldn't say what was wrong with it.

Problem

The copy was statistically unlike the client's real voice, and there was no way to argue about it productively. Voice disputes die as taste debates: one person feels the slop, another defends the draft, and nobody can point at anything.

Approach

The measurements resolve into a numeric profile of how this one business sounds, and the copy got rebuilt against it.

Stack

  • Python metric engine, nine metric families spanning lexical, rhythm, punctuation, and sentiment axes
  • Corpus extraction across hundreds of client-authored assets
  • A rebuild written to the measured numbers

Result

241
client reference pieces measured

On a first measurement, the rebuild landed inside the client's range. Nobody had to trust a writer's ear, because the distance between the first round and the client's voice was a number anyone could check.

Impact

Writing quality at this studio became an inspectable number rather than a taste argument. When a future draft drifts from the voice, the drift shows up as a measurable distance before a customer ever sees it.

Lessons

AI-written content is converging on one voice, a new dialect of the internet. Conversion copy that works in the coming decade gets written in a way no other agent writes and most humans don't think. I check that with a measurement instead of my own ear.

Who this is for

For any business whose brand voice is worth protecting, and who'd rather catch drift with a measurement than argue about taste.
