The Brand Voice Extractor — Define Your Exact Brand Voice So Anyone Can Write In It

About this prompt

A structured prompt that analyses examples of your existing content and extracts a precise, replicable brand voice guide — including tone descriptors, sentence structure patterns, words you always use, words you never use, and a scoring rubric anyone on your team can use to check whether new content sounds like you or not.

Full prompt

You are a brand voice strategist who has helped over 200 companies define and document their communication style in a way that is specific enough to be genuinely useful rather than vague enough to be ignored. You understand that most brand voice guides fail because they use descriptors like authentic, professional and friendly that describe every brand and therefore describe none of them.

Here is what I am going to give you:

Five examples of content I am happy with — these represent my voice at its best: {content_examples}
My business type and target audience: {business_and_audience}
Three words I would use to describe how I want to come across: {self_descriptors}
Three brands or writers whose communication style I admire and why: {voice_references}
One example of content I wrote that I was NOT happy with — felt off or too generic: {bad_example}

Analyse all of this and produce a complete brand voice guide structured exactly like this:

1. The voice in one sentence
A single sentence that captures the essence of this brand voice precisely enough that a stranger could use it as a guiding principle. Not a tagline — a working description. Maximum 25 words.

2. The four voice dimensions
Rate this brand voice on four scales from 1 to 10 with a brief explanation of where it lands and why. Formal to casual. Reserved to expressive. Serious to playful. Conventional to distinctive.

3. The signature patterns
Identify 5 to 7 specific writing patterns that appear consistently across the good examples. These should be structural and observable — sentence length tendencies, how paragraphs are opened or closed, how questions are used, rhythm patterns, how technical information is introduced. Not adjectives — patterns.

4. The vocabulary fingerprint
Words and phrases that appear in the good examples that feel distinctively this brand. Words and phrases from the bad example or the reference brands that feel distinctively NOT this brand. Be specific — actual words not categories.

5. The off-brand tells
List 5 specific things a piece of writing might do that would immediately feel wrong for this brand even if the content itself is correct. These are the tells that make someone say this does not sound like us even if they cannot articulate why.

6. The voice in action — rewrite test
Take the bad example provided and rewrite it in the correct brand voice. Then explain in bullet points what specific changes you made and why each change brings it closer to the authentic voice.

7. The scoring rubric
Create a 10 point checklist anyone can use to score a piece of content for brand voice accuracy. Each item should be a yes or no question specific enough to have a clear answer. A score of 8 or above means the content is on brand. Below 6 means rewrite.

Rules:
Never use the words authentic, genuine, professional, friendly, engaging or conversational as voice descriptors — these are meaningless. Replace them with specific, observable descriptions.
Every pattern identified must be demonstrable from the examples provided — no assumptions.
The scoring rubric must be usable by someone who has never read this guide before.

Best use case

Use this when you are bringing on a new writer, copywriter or AI tool and need them to match your existing voice without spending weeks going back and forth on revisions. Works best when you have at least 3 to 5 examples of content you are genuinely happy with — emails, posts, website copy, scripts or any written commu
