Brand voice extractor prompt

Paste your three best pieces of writing; get a reusable voice guide — rules, vocabulary, and before/afters — that keeps every future AI draft on-brand.

Last reviewed July 13, 2026 brandingwriting

You already have a brand voice — it’s in your best emails and pages. The problem is it lives nowhere an AI (or a new hire) can use it. This prompt extracts it into a portable voice guide: the writing equivalent of the design tokens described in Design tokens in plain English.

The prompt

Analyze the writing samples below and extract a reusable BRAND VOICE GUIDE.
Describe only what's actually present in the samples — don't import generic
"brand voice" advice.

Output:
1. VOICE SUMMARY — the personality in 2-3 sentences, as instructions to a
   writer ("Write like...").
2. RULES — 5-8 concrete do/don't rules observable in the samples
   (sentence length, formality, humor, how claims are made, greetings/sign-offs).
3. VOCABULARY — words/phrases we actually use; words that would feel wrong.
4. BEFORE/AFTER — take two generic business sentences and rewrite each in
   this voice, so the difference is visible.

Format it so I can paste the whole thing into another AI's instructions as
"write in this voice."

How to adapt it

Choose samples you’re proud of, not recent ones — the guide clones whatever you feed it.
Test it immediately: give the guide + a boring announcement to a fresh chat and see if the output sounds like you. Fix the rules it gets wrong.
The output slots directly into the VOICE line of Lead reply drafter prompt and Proposal narrative generator prompt, and into the playbooks in The AI playbook template.
