Create a one-page brand voice guide for [BRAND].

What we sell: [PRODUCT]
Our customers: [CUSTOMERS]
Brands whose tone I like: [EXAMPLES]
Words I want to be known for: [VALUES]

Include four voice traits with a "we are / we are not" line for each, words to use and avoid, sample rewrites of a bland sentence in our voice, and how the tone shifts for support, social and legal messages.

Add three real sentences you would say and three you would never say; examples beat adjectives.

What you will get

A one page voice guide: four traits with a “we are, we are not” line each, a short list of words to use and avoid, a bland sentence rewritten in your voice, and how the tone changes for support, social and legal text.

Why it works

Most voice guides fail because they list adjectives nobody can act on. This prompt asks for contrasts and rewrites instead, which is what a writer actually checks against. Naming brands whose tone you like gives the model a target it already knows, and listing the values you want to be known for keeps the traits tied to your business.

Common mistake

The traits are adjectives every brand uses, like friendly and professional.

Fix: Ask for each trait to come with the opposite you refuse, such as “warm, not gushing”, and a sentence that shows the line between them.

Also watch for

The guide sounds like a big company, not like you. Paste three real things you have written to customers and ask it to build the traits from those, as the tip says.
The legal and support tone is just “more formal”. Ask for a real example of each: a refund refusal and a delay apology, written in your voice but with the extra care those need.

Try a variation: make a cheat card

Ask for a half page version for new team members: the four traits, five banned words and three before and after rewrites.
