What Is a Brand Voice Guide?
Simply put, a brand voice guide is a lifetime document that defines how your business sounds across all communication channels. Think of it like brand guidelines, but focused on voice — the personality, tone, and style your business uses in writing emails, social media posts, website copy, presentations, and even in-person conversations.
This guide ensures that anyone communicating on behalf of your business—whether it’s you, an employee, or a hired professional—does so consistently and authentically. It’s the foundation of how you connect and engage with your customers and audience.
Do You Need a Brand Voice Guide?
If you’re just starting your business, you might not need a formal brand voice guide right away. However, it can be helpful if you find it challenging to communicate your message clearly and consistently. Here’s when a brand voice guide becomes essential:
Hiring employees: When you bring someone on board to help with writing, customer service, or communications.
Outsourcing work: If you hire copywriters, social media managers, graphic designers, or virtual assistants who create content on your behalf.
Scaling your business: As your business grows, maintaining a cohesive voice across platforms becomes critical to building trust and brand recognition.
In these cases, a brand voice guide ensures everyone involved in your business communications stays aligned with your brand’s personality and messaging style.
How to Use ChatGPT to Discover Your Brand Voice
I recommend a simple and effective way to use copywriting artificial intelligence—specifically ChatGPT—to help you uncover your brand voice. Here’s a step-by-step process:
Open ChatGPT: If you haven't already, create an account and log in to access the main chat screen.
Prepare your prompt: Type the following prompt - “Analyze this text for tone of voice and style;” then paste a piece of writing you’ve already created for your business.
Choose your writing samples: Select content from different areas such as social media captions, website copy, blog posts, or podcast descriptions. The more varied the samples, the better the analysis.
Submit and review: Let ChatGPT analyze the tone, style, and key characteristics of your writing and provide descriptive adjectives.
Repeat: Do this exercise three to five times with different samples to identify consistent themes and adjectives that define your natural brand voice.

Example Analysis
For example, when I pasted one of my Instagram captions into ChatGPT, it identified the tone as conversational, supportive, and encouraging, with casual language that conveys confidence and authenticity. The text empathizes with audience struggles and counters misconceptions about social media marketing—perfectly aligned with my brand.
Another example from a podcast episode description was analyzed as insightful, inviting, and enthusiastic, focusing on personal growth and curiosity. While some adjectives varied slightly, the core themes of empowerment, education, and authenticity remained consistent like my brand should be.
Best Prompts to Train ChatGPT in Your Brand Voice
Here are some prompts that help ChatGPT understand and replicate your brand voice:
“Rewrite this Instagram caption in a casual, empowering tone to match my brand voice.”
“Write a blog intro in the voice of a warm, confident educator that infuses my brand's personality and tone.”
“Act as a brand strategist. Analyze this writing and summarize the tone.” (great for if you don't have a brand voice yet or need to double check your writing is on brand)

What Makes AI Copywriting Different From Human Copywriting?
AI can produce content at lightning speed. But it’s not human—and it doesn’t understand your values, your unique point of view, or your audience’s emotional triggers.
That’s why I always say: use AI to assist, not replace. Let it help you brainstorm, structure ideas, and maintain voice consistency—but always review and edit with a human touch for deeper connection and accuracy.
How to Spot When Your Brand Voice Is Off
Feeling like your content sounds a little… off? Here are a few signs:
You're getting lower engagement
Feedback like “This doesn’t sound like you”
Confusion in your audience or inconsistent messaging
If this happens, go back to ChatGPT and run a tone analysis. Recenter your voice by reviewing your adjectives and reapplying them in your writing prompts.
Your brand voice can slowly get off track even when you're not using AI tools for content creation. Overtime our writing evolves, and our moods can impact our writing style. using tools like ChatGPT to proof read and analyze human written content before posting can be helpful to maintain brand ocnsistence if you're not regularly working with a copywriter.
Should You Use Copywriting Artificial Intelligence for Sales Pages and Launches?
Yes and no. Use ChatGPT or other AI tools to help draft frameworks, create options, and refine tone. But when it comes to high-stakes copy like sales pages or launch emails, your human touch (and copywriters) matters.
AI can’t replicate your lived experience or storytelling. Use AI as a powerful starting point, then layer in your personality, strategy, and unique voice.
Using Your Brand Voice Guide in Practice
Once you identify the key adjectives and tone descriptors that define your brand voice, you can use them to guide all your content creation. Here’s how:
Content creation with ChatGPT: When asking ChatGPT to write social media captions, blog posts, or emails, include your brand voice adjectives in the prompt. For example, say, “Write this in an empowering, relatable, casual, and educational tone.”
Communicating with your team: Share your brand voice guide with any employees, freelancers, or agencies working on your content. This ensures consistency across all platforms and touchpoints.
Maintaining consistency: Your brand voice should be a seamless experience for your audience, whether they’re reading your social media posts or browsing your website. Slight variations are okay depending on the platform, but the core voice must remain consistent.
For instance, social media content might lean more motivational and casual, while website copy could be more educational and focused on conversion. Both should still reflect your overall brand voice.

Copy.ai – Great for branded templates and brainstorming
