How to Train AI to Write in Your Brand Voice

The most common complaint about AI-generated content is that it sounds generic. It sounds like everyone else.

That is a prompting problem, and it is fixable with a brand voice document.

What is a brand voice document?

It is a reference file you give to the AI at the start of every session. It tells the AI:

• •Who you are
• •Who your audience is
• •How you talk (and how you do not)
• •Your tone and personality
• •Words you use (and ban)
• •Examples of your writing

Once you have this document, you paste it into every AI session, and the outputs start sounding like you.

How to build yours in 30 minutes

1. Describe your brand in 3 adjectives Not generic ones like "professional" or "friendly." Try: "direct, slightly irreverent, genuinely helpful."

2. Describe your audience in one sentence "Freelancers aged 25 to 40 who are smart but time-poor and allergic to corporate jargon."

3. Write your voice rules - Do: short sentences. Direct language. Real examples. - Do not: exclamation points. Passive voice. Corporate buzzwords (leverage, synergy, circle back).

4. Include 3 writing samples Copy-paste three pieces of your own writing that feel most like you. These are the examples the AI will mirror.

5. Add your banned word list Mine includes: amazing, awesome, game-changer, seamless, robust, and "at the end of the day."

How to use it

Start every AI session with:

"I am going to share my brand voice guide with you. Please use it as your style reference for everything you write in this session."

Then paste your document.

That is it. Every output in that session will be calibrated to your voice.
