Build Your Own Voice Guide

Stop guessing your tone. Start with one real client and let this skill reverse-engineer the rest — no adjectives, no self-report, just real language, your natural working style, and the words you can't stand.

Before You Start
A Claude account on a paid plan — you'll need this for the conversation to work well (claude.ai/upgrade)
This guide open alongside your Claude chat — two windows or two tabs works great
30–45 minutes for your first pass — longer if you want to test the finished voice against a few pieces of writing
1Your Real Person
2Your Working Style
3What You Can't Stand
4Build Your Voice

Keep this guide open in one tab. Open Claude.ai in another. You'll paste each prompt directly into your Claude chat.

Step 1 of 4 — Your Real Person

One real person, not a persona.

Before we can find your voice, we need one real person to build it around. Not a composite, not a demographic — one actual human. Open a new Claude chat by selecting "New Session," then paste the prompt below. Keep talking with Claude and answering its follow-ups — don't move on until the reflection back actually feels right.

Never had a client yet? Don't skip this step — there's a path built right into the prompt below for finding real language even without client history.
Paste to Claude
I'm building a custom brand voice guide for my business, and I want it grounded in one real client — not a persona or a demographic description. Ask me about one specific person I've worked with who was a genuine dream client:

1. Who are they? (First name or initials is fine — this stays private.)

2. What was going on for them right before they found me — what were they frustrated by, worried about, or stuck on? Use their own words if you can remember them, not my professional translation.

3. What did they actually say or write when they first described their problem to me? I want their real phrasing, not the cleaned-up version.

4. What did they say to me afterward — a testimonial, a DM, a comment, anything close to their actual words?

5. If I can only describe a type of person rather than one real individual, push back and make me think harder — a demographic isn't specific enough to build a voice from.

If I've never had a client yet, don't ask me to invent one. Instead ask: have you seen someone else describe this exact problem — a comment, a post, a DM you received, a forum thread? Or, if easier: think back to before you solved this for yourself — what were you frustrated by, worried about, or stuck on? Use your own real words from that time. Either way I need one real person's real language, never a made-up composite.

Once I've answered, reflect back the actual language patterns you're noticing in how they talked about their problem — not just the facts, the phrasing itself. Ask follow-ups if it's still vague.
Answer as specifically as you can. Even a partial memory helps. When Claude reflects real language back and it feels right, move to Step 2.
Step 2 of 4 — Your Working Style

How you work decides who you attract.

This is the part most brand-voice tools skip entirely — and it decides who your voice should attract, not just who it should describe. Paste this into the same Claude chat.

Paste to Claude
Help me capture how I actually work, so my voice attracts people who are a genuine fit for how I operate — not just people who need what I sell.

1. How do I communicate best — bottom-line and direct, full-context and thorough, or exploratory and collaborative? Be honest about my natural gear, not the one that sounds more professional.

2. What client behaviors energize me, and which ones drain me?

3. How do I handle a client who's anxious, scattered, or in crisis — what can I work with, and what's beyond my capacity?

4. If I'm unsure of my own style, ask me questions to draw it out — or suggest a quick free personality or DISC assessment I can take and bring back.

Once I've answered, translate this into what it means for my voice: what tone will feel true to how I actually work, and what tone would attract someone who'd clash with me even if they need what I do.
Don't rush this one. A voice that's professionally accurate but personality-mismatched still attracts the wrong clients. When it feels honest, move to Step 3.
Step 3 of 4 — What You Can't Stand

Name what makes you cringe.

Often faster to name than what you want — and just as useful. Paste this into the same Claude chat.

Paste to Claude
Now let's get clear on what I don't want my voice to sound like.

1. What phrases or words make you cringe when you see them in other people's marketing in my industry?

2. Is there a specific word or phrase you refuse to use, even if it's common in my industry? Why?

3. Think of a piece of marketing that felt fake or off the moment you read it — even if you couldn't say why at the time. What was it about the writing itself, not the offer, that felt wrong?

4. Any formatting habits you dislike — too many exclamation points, emoji, ALL CAPS, buzzwords?

Push back if my answers are too general — "I don't like being salesy" isn't specific enough. Help me name actual words and patterns. Hold onto this as a banned list for Step 4.
The more specific your dislikes, the sharper your voice guide will be. When you've got real examples, move to Step 4.
Step 4 of 4 — Build Your Voice

Where it all comes together.

This is where Claude does the work you can't do yourself — deducing your voice from what you actually wrote, not from what you said about yourself. Paste this into the same Claude chat.

Paste to Claude
Based on everything I've told you — my real client, my working style, and what I can't stand — build my brand voice guide. Don't ask me to describe my tone in adjectives. Instead:

1. Look back at how I actually wrote my answers in Steps 1 and 2 — sentence length, contractions, formality, where I got energetic or blunt. Tell me the patterns you noticed in my own natural writing, not what I said about myself.

2. Cross-reference that against my banned list from Step 3.

3. Reference my real client's actual language from Step 1 — the voice should land specifically with someone who talks and thinks the way they do.

4. Give me: a plain-language description of my voice (not just adjectives), 5-8 concrete do's, 5-8 concrete don'ts, and 2-3 example sentences rewritten in my voice.

5. Tell me who this voice will attract and who it will likely filter out, so I can check it against my real client from Step 1.
Read the finished guide against your real client from Step 1 — does it sound like something they'd trust? Adjust with Claude until it does, then move on to save it.
Keep It Forever

Save your voice as a Claude skill.

The best way to keep your voice guide is to install it as your own Claude skill — so it's always there, no copy-pasting, ready anytime you're writing something.

Paste to Claude
Please format this as a SKILL.md file I can upload as a custom skill. Give it a short name, a clear description of when to use it (so it triggers whenever I'm writing anything — emails, posts, sales pages — and want it in my voice), and put my finished voice guide in as the instructions, including the do's, don'ts, and example sentences.
1
Save the file
Save Claude's output into a file named SKILL.md — keep that exact name.
2
Zip it
Put that file inside a folder, then zip the folder (Mac: right-click → Compress. Windows: right-click → Send to → Compressed folder).
3
Turn skills on
In Claude, go to Settings → Capabilities and switch on Code execution and file creation.
4
Upload your skill
Go to Customize → Skills, click +, then + Create skill, then Upload a skill. Choose your zip and toggle it on.
5
Use it anytime
In any new chat, paste a draft and say: "Rewrite this in my voice." Claude loads it automatically.

Your voice is built.

You didn't describe your tone — you proved it, from a real client's actual words and your own natural writing. Now it's yours to run anytime.

What You Built
A voice guide built from one real client's actual language — not invented adjectives
Working-style signals that filter for compatible clients, not just qualified ones
A banned-words list built from what you can't stand
Concrete do's, don'ts, and example sentences rewritten in your voice
Next Time You Write Something

Open Claude. Paste your draft — an email, a post, a sales page. Say: "Rewrite this in my voice." Your skill loads automatically and applies everything you just built.
