Brand voice · built to operate
I build brand voices a team can actually run.
Most brand voice guides describe a vibe and hope the next writer absorbs it. I build the opposite: a guide where every attribute is pulled from your own writing, the rules are explicit, and a new hire or an AI tool could ship on-brand with it on day one.
every trait is two real lines from your writing, or it is not in the guide ↓How it works
- 1
You send your writing
A few thousand words across a couple of formats. A newsletter and a complaint reply teach more than a dozen captions.
- 2
I infer the voice
Every attribute is backed by two real lines from your own writing, or it does not make the guide. No vibes, no invention.
- 3
I draw the rules
A numbered never-list and channel playbooks: the rules your team and your AI tools actually follow, each with a why that generalizes.
- 4
You get one guide
Plain markdown, in a fixed structure, that a new hire or an AI could ship on-brand with on day one. It runs anywhere.
Voices I’ve built
Three sample voices across three very different brands. Same method, same fixed output. Flip between them and copy the finished guide.

# Acorn Pediatric Dentistry Brand Voice Guide ## North star The child sets the pace, not the schedule. ## Core tension Calm reassurance, between clinical and saccharine. ## Voice attributes **Reassuring, never saccharine.** Name the scary thing plainly, then take the pressure off. No forced cheer. - Failure mode: saccharine. Bright-side cheer a nervous kid does not believe. - Evidence: "You don't have to be brave, you just have to show up." / "If your little one cries, that is okay." - Test: Would a nervous seven-year-old believe it, or feel managed? **Patient on the kid's clock.** The child's readiness sets the timing, even when it costs minutes. - Failure mode: clinical. Efficiency that treats the child as the next slot. - Evidence: "we never rush a scared kid." / "We would rather spend ten extra minutes letting your child hold the mirror than start before they are ready." - Test: Does the sentence put the child's pace ahead of the schedule? ## Never-list (single source of truth) | ID | Never | Use instead | Why (generalizes) | |----|-------|-------------|-------------------| | NV-01 | "state of the art", "gentle, caring dentistry", "your smile is our priority" | name the specific thing you do for a scared kid | category slogans every clinic shares signal nothing and cannot be verified; catches any interchangeable tagline | | NV-02 | "don't worry", "it won't hurt a bit" | say what will actually happen, step by step | a promise a child cannot trust breaks the first time it is wrong; describe the next step, do not reassure blindly | | NV-03 | paired em-dashes, "delve", "it is worth noting" | plain sentences; cut the throat-clearing | these read as machine-drafted; the principle strips anything that signals generated text | ## Channel playbooks **Appointment reminder (text, to the parent).** The job: lower the dread before the visit. - On-brand: "Big day tomorrow for [Child]. They don't have to be brave, just bring them at 3:00 and we will take it slow." - Off-brand: "Your appointment is confirmed. Our state-of-the-art team looks forward to your visit!" (breaks NV-01) **Cost conversation.** The job: no surprise bills, ever. - On-brand: "Two fillings, $180 each. We will tell you the full number before we pick up a single tool." - Off-brand: "Affordable, transparent pricing tailored to your family's needs." (breaks NV-01) ## AI prompt pack Universal context (paste once per session): "Write as Acorn Pediatric Dentistry. North star: the child sets the pace, not the schedule. Be reassuring but never saccharine, patient on the kid's clock. Never use clinic slogans, blind promises like 'it won't hurt', or em-dashes. Name the specific thing, give the real number." Task prompt (reminder text): "Draft a two-sentence reminder for [appointment]. Lower the dread, name the time, and promise to go at the child's pace. No slogans, no 'don't worry'." ## Validation note Checked a line not quoted above: "No surprise bills." Passes: plain, specific, no banned terms. The clinic's own writing scores on-brand, so no rule needs loosening.
Why mine hold up
Evidence over invention
No attribute survives without two real lines from your own writing. You get a voice you can prove, not one a model averaged out.
The sharpness bar
Anything that would fit any brand in your category gets cut. You get a voice that is yours, not the category average in three adjectives.
