One-Line Summary: Document your brand's tone, values, and target audience into a structured voice guide that AI can reference every time it writes for you.
Prerequisites: Completed Step 1, access to Claude or ChatGPT
Why Brand Voice Matters
If you skip this step and jump straight to generating posts, every piece of content will sound generic. AI writes differently when you tell it "write a LinkedIn post" versus "write a LinkedIn post as a friendly but knowledgeable fitness coach who uses casual language and real-world analogies."
Your brand voice guide is the single most important asset in this entire workflow. You will paste it into every prompt going forward.
Gather Your Brand Details
Before opening AI, answer these questions on paper or in a notes app:
- What do you do? (one sentence)
- Who do you serve? (specific audience, not "everyone")
- What makes you different? (your unique angle or approach)
- What three adjectives describe your brand? (e.g., bold, approachable, expert)
- What words or phrases do you never use? (e.g., "synergy," "circle back," slang)
- Name a public figure or brand whose tone you admire. (This gives AI a reference point)
Generate Your Brand Voice Guide
Open Claude or ChatGPT and paste this prompt. Replace the bracketed sections with your actual answers:
I need you to create a Brand Voice Guide for my social media content.
Here are my details:
Business/Brand: [Your business name]
What I do: [One sentence about your product or service]
Target audience: [Who you serve - be specific about age, interests, pain points]
Unique angle: [What makes you different from competitors]
Brand personality: [Three adjectives, e.g., "warm, expert, slightly humorous"]
Tone inspiration: [A brand or person whose communication style you admire]
Words/phrases to avoid: [List any language that feels off-brand]
Please create a structured Brand Voice Guide that includes:
1. Brand Voice Summary (2-3 sentences)
2. Tone Attributes (with descriptions and examples for each)
3. Language Do's and Don'ts (specific words and phrasing)
4. Audience Personas (2-3 brief profiles of ideal followers)
5. Sample sentences in my brand voice (5 examples)
6. Platform-specific tone adjustments for Twitter/X, LinkedIn, Instagram, and FacebookExample Output
Here is what a completed brand voice guide looks like for a fictional coffee roaster:
Brand Voice Summary: Brew & Bean speaks like a knowledgeable friend who happens to be obsessed with great coffee. We are warm, educational, and occasionally witty. We never talk down to beginners but we respect the craft enough to go deep when it matters.
Tone Attributes:
- Warm — We greet our audience like regulars walking into the shop. "Morning! Let's talk about why your French press coffee tastes bitter."
- Educational — We teach without lecturing. "Fun fact: water temperature matters more than grind size for most brewing methods."
- Witty — Light humor, never forced. "Life's too short for bad coffee. And Mondays are too long for decaf."
Language Do's and Don'ts:
| Do Use | Don't Use |
|---|---|
| "Here's a tip" | "You should" |
| "We've found that" | "Studies prove" |
| "Game-changer" | "Revolutionary" |
| First names, casual greetings | Corporate jargon |
Save Your Voice Guide
Copy the AI-generated voice guide and save it somewhere accessible. You will paste it into prompts throughout this blueprint. Good places to store it:
- A pinned note in your notes app
- A Google Doc or Notion page
- A text file on your desktop
Create a Reusable Prompt Prefix
To save time, create a short version you can paste at the top of every future prompt:
You are my social media content writer. Here is my brand voice:
[Paste your 2-3 sentence Brand Voice Summary]
Tone: [Your three adjectives]
Audience: [One sentence about who you serve]
Never use: [Your avoid list]
Now, using this voice, please:This prefix takes 10 seconds to paste and ensures every piece of content stays on-brand. Think of it as your AI's personality settings.
Test Your Voice Guide
Before moving on, run a quick test. Paste your prompt prefix followed by:
Write three short social media posts (2-3 sentences each) about
[a topic relevant to your business]. Make each one a different style:
one educational, one promotional, one engaging/conversational.Read the results out loud. Do they sound like you? If something feels off, refine your voice guide:
- Too formal? Add "use casual, conversational language" to the tone
- Too salesy? Add "focus on value over selling" to the do's list
- Too generic? Add more specific vocabulary from your industry
- Missing personality? Add a line like "occasionally use humor" or "reference pop culture"
Iterate until the output reads like something you would actually post. This investment pays off in every step that follows.
