Does your website sound formal, your social content sound playful, and your marketing emails sound like they came from another business?
A brand voice guide gives your writing a consistent starting point. Instead of asking AI to “sound professional,” you explain how your business communicates, which words fit, and which claims it must avoid.
To create a brand voice guide with AI, provide your actual services, target audience, preferred personality, and a writing sample. Then review the suggested rules, test them on real content, and remove anything that misrepresents your business.
Here is a practical approach, including a reusable template and examples using Stellar Sixty6.
What Is a Brand Voice Guide?
A brand voice guide describes how your business should sound in writing. It helps you, your team, and AI writing tools make consistent choices.
A useful guide includes:
- Your audience and what they need to understand.
- Voice characteristics supported by examples.
- Rules for vocabulary, sentence structure, and formatting.
- Words and unsupported claims to avoid.
- Before-and-after examples of copy.
It does not need to be a lengthy branding document. A short guide with specific instructions is more useful than pages of adjectives nobody knows how to apply.
Brand Voice vs Tone: What Is the Difference?
Voice is your consistent personality. Tone changes with the situation.
A friendly, straightforward business can sound enthusiastic when announcing a service and calm when explaining a delay. It should still sound like the same business.
For example, “Your website design is ready to review” and “We need one more detail before we can finish your design” share a clear voice while addressing different situations.
Your guide should allow that flexibility instead of requiring every message to sound equally cheerful.
1. Start With Facts About Your Business
Before choosing a personality, write down what you actually offer. AI needs this information to avoid filling gaps with invented services or benefits.
Here is an example brief for Stellar Sixty6, using the confirmed service scope:
Business: Stellar Sixty6
Services: Website design and development.
Audience: Business owners who want to establish an online presence.
Scope: Design and development only. Hosting and ongoing maintenance are not included.
This is more useful than “helping businesses succeed online” because it explains what customers receive.
Keep customer goals separate from product claims. A customer wanting more sales does not establish that your service increases sales. Similarly, offering development does not automatically mean you provide hosting, SEO, or ongoing technical support.
2. Describe the Reader’s Situation
“Business owners” identifies a broad audience. Adding their situation gives the writing a clearer purpose.
For a campaign aimed at first-time website buyers, you could write:
Business owners planning their first website who are unfamiliar with design and development terminology. They want to understand the deliverables before making a decision.
Only use that description if it matches your intended customers. It suggests practical writing choices: explain unfamiliar terms, describe the scope clearly, and avoid assuming technical knowledge.
You do not need an elaborate customer persona. Focus on what the reader is trying to do and what they need explained.
3. Turn Personality Into Writing Rules
“Friendly,” “confident,” and “professional” are starting points, not complete instructions. Translate each characteristic into something a writer can apply:
- Friendly: Address the reader naturally without forced jokes or exaggerated enthusiasm.
- Clear: Name the service directly and explain unfamiliar terms.
- Confident: State confirmed capabilities without superlatives or guaranteed outcomes.
For Stellar Sixty6, “We design and develop websites for business owners” fits those rules better than “We deliver revolutionary digital experiences.”
Avoid rigid rules such as “Every sentence must be short.” Prefer concise sentences, but allow enough detail to explain the offer properly.
4. Add a Writing Sample and Boundaries
A short passage you genuinely like can communicate your preferences more clearly than a long list of adjectives. An illustrative sample for this brief could be:
Planning a website for your business? Stellar Sixty6 offers website design and development. Hosting and ongoing maintenance are outside our service scope.
Ask AI to identify useful patterns in the sample, such as direct wording and transparent scope, rather than repeating its sentences everywhere.
Also list boundaries. These might include avoiding “guaranteed results,” not implying hosting is included, or never stating an unconfirmed turnaround time. Remove private customer information from any examples you share.
5. Generate Your First Brand Voice Guide
Use the Wise Minds AI Brand Voice & Style Guide Generator to turn your brief into proposed voice guidance.
Enter your brand name, actual capabilities, and audience. Add values, a writing sample, and prohibited claims when available. Choose a personality, tone, and writing channel suited to your needs.
Treat the result as an editable proposal, not verified information about your business. For another AI writing workflow, adapt this prompt:
Create a practical brand voice guide using the business brief below. Separate supplied facts from suggested writing preferences. Include a voice direction, editorial rules, preferred vocabulary, words to avoid, and two before-and-after examples. Do not invent services, results, credentials, or commitments. If information is missing, ask a question rather than assuming an answer. Explain how the voice should adapt to my selected writing channel.
Business brief: [Insert your confirmed business information.]
Writing sample: [Insert an approved example, if available.]
Primary channel: [Website, email, social media, or another channel.]
6. Review the Examples, Not Just the Rules
A guide can say “avoid unsupported claims” and still introduce one in its examples. For Stellar Sixty6, compare these versions:
Unsupported: “We build high-converting websites that grow your business.”
Grounded alternative: “Stellar Sixty6 designs and develops websites for business owners.”
Development is part of the confirmed offer. The problem is the unverified conversion and growth claims.
Also check whether the rewrite is genuinely better. Replacing ordinary words with polished jargon is not an improvement. A useful rewrite makes the meaning easier to understand while retaining accurate details.
A Brand Voice Guide Template for Small Business
Use this structure to keep your approved guide easy to reference:
Brand name:
Confirmed products or services:
Target audience and situation:
Voice characteristics:
What each characteristic means in practice:
Preferred words:
Words and unsupported claims to avoid:
Sentence and formatting preferences:
Tone adjustments by channel:
Approved example copy:
Details that still need confirmation:
Keep suggested preferences separate from established facts. Choosing a helpful voice does not mean your business offers ongoing support.
7. Test the Guide on Real Content
Try the guide on a homepage introduction, an email, and a social post. Compare the results using the same questions:
- Is every service and benefit supported by the brief?
- Would the intended reader understand the message?
- Does the writing sound recognizably consistent?
- Does the tone suit the situation?
- Has AI repeated phrases or introduced generic filler?
Revise the guide when you find a recurring problem. If every paragraph begins with “We,” add a preference for varied sentence openings instead of rewriting each paragraph separately.
Once the guide works, use it when repurposing content with AI so different formats retain a consistent voice.
Frequently Asked Questions
Can I create a brand voice guide without existing content?
Yes. Start with confirmed services, the reader’s situation, and a few writing preferences. Treat the initial guide as provisional and improve it as you approve real examples.
Will AI remember my brand voice automatically?
Do not assume it will. Include the approved guide in each writing brief unless your chosen tool explicitly stores and applies it.
Is a brand voice guide the same as a visual brand guide?
No. A voice guide covers language and communication. A visual guide covers elements such as logos, colors, typography, and imagery.
How do I stop AI from making my brand sound generic?
Give it concrete writing examples, an accurate service description, and specific editorial rules. Review the output for vague phrases that could describe almost any business.
Create a Guide You Will Actually Use
The goal is not to make every sentence sound identical. It is to make your writing consistent, understandable, and accurate.
Start with your real offer, define a few usable rules, and test them before approving the guide. Use the brand voice generator for your first draft, then make the final editorial decisions yourself.
