Brand Voice Builder

Turn three examples of your own writing into a reusable voice file — the document you paste into any AI tool before asking for content, so it sounds like you instead of like everyone. It assembles live as you type.

Everything runs in your browser. Nothing you type is stored or sent anywhere.

From the article: How to write marketing content for your shop with AI →

Up to three real things you've written that sound like you

Not your best marketing — your most you. A WhatsApp message to regulars counts. The file needs at least one.

One per line. “Delightful”, “indulge”, “elevate your experience” — whatever makes you cringe.

Two lines is enough. “Mostly regulars from the nearby offices. We joke with them. No hard selling.”

Updates as you fill in the form. Blanks stay in the document until you answer them — or fill them in after copying.

# Brand voice file — my business

This file teaches an AI tool how my business writes — the tone, rhythm, and
word choice. Paste the entire file into your AI tool at the start of a
session, before asking for any content. Update it whenever your business
changes.

## Who we're talking to
(Add two lines here: who your customers are, and how you talk to them.)

## What I actually sound like (real samples)
1. "____________ (paste a real message you've written here)"

## Words and phrases we never use
- (none listed yet — add the ones that make you cringe)

## Writing rules
- Match the tone, rhythm, and word choice of the samples above. When unsure, sound more like them, not less.
- Emojis and exclamation marks: only if the samples use them, and sparingly.
- Plain language. If a sentence could appear in any shop's post, rewrite it.
- Every post needs one concrete detail only my business could know. Leave a [DETAIL] blank for me to fill in.

## Instruction to the AI (include this too)
You are drafting content for my business. Write in the voice of the samples
above. Never use the banned words or phrases. Do not invent facts, prices,
offers, or events — leave a [DETAIL] placeholder for anything you don't
know. You draft; a human reviews and approves everything before it is
published.

It's yours to edit — trim anything that doesn't sound right, and keep it next to your AI tool.
