Why voice drifts (and why nobody notices until it's bad)
Here's the thing: drift isn't one big mistake. It's death by a thousand small ones. Three writers, two AI tools, six months, and suddenly your blog reads like four different companies took turns writing it. Nobody signed off on that. It just happened, slowly, the way these things do.
The usual fix is a style guide nobody reads and a reviewer going "hmm, feels off" in a comment thread. That's not a system. That's a vibe check.

1. A measured baseline, not a mood board
ScriptGrain runs a two-pass stylometric analysis across your real copy and pulls out 45 attributes: sentence rhythm, contraction rate, hedging, humour register, the lot. That becomes your baseline. Not an adjective list. A number.
2. A voice-match score on every draft
Every piece of AI-generated copy gets scored against that baseline before it reaches a reviewer. High score, ship it. Low score, you know exactly where it slipped, tone, structure, vocabulary, whatever. No more "this feels wrong" meetings. Just a number and a reason.
3. One baseline, every writer
Profiles are shared across the team, so every draft answers to the same 45 measured attributes. Same voice, whoever happens to be writing today. And to be fair, that's most of the value right there: one standard that outlives whichever tool is trendy this quarter.
4. The tie-breaker document
Disagreements about brand voice usually come down to two people with two opinions and no referee. The profile ends that. It's not "I think this sounds off." It's "this scored 61 against a baseline of 90." Harder to argue with.
5. Built for teams, not just one writer
Studio and Agency plans give whole teams shared profiles, shared scoring, shared standards. No more one writer's taste quietly becoming "the brand."

Young category, vague promises, everyone claiming they've "cracked brand voice." Fair enough. But a promise isn't a score.
Get your baseline free. No card, one profile, five minutes.
Then watch drift become a number your team can actually check, not a feeling somebody has to defend in a meeting.
