In the last episode, we explored how to automate business workflows using GPT. Now, we’ll focus on how to make your GPT sound like your brand, ensuring consistency across all communications.
By the end of this episode, you will know:
- How to define your brand’s tone and style for GPT.
- How to adjust GPT’s personality to fit your business needs.
- How to refine GPT’s responses to align with your brand identity.
Let’s get started.
Step 1: Defining Your Brand’s Tone and Style
Every business has a unique communication style. Some brands sound friendly and casual, while others are formal and professional.
Before customizing GPT, you need to define:
- Tone – Is your brand friendly, professional, authoritative, or playful?
- Formality level – Do you use casual or business-like language?
- Sentence length and complexity – Should responses be short and direct or detailed and informative?
For example, if your company is a tech startup, you might want a modern, conversational tone. If you’re in finance or law, you may prefer a professional and precise tone.
Decide what fits your business, then apply it to your GPT’s customization settings.
Step 2: Setting Personality Traits for GPT
You can adjust GPT’s personality to match your brand’s communication style.
Some personality traits to consider:
First, Friendly and engaging – Best for brands that focus on customer relationships and social engagement.
Second, Authoritative and professional – Ideal for businesses in finance, legal, or B2B industries.
Third, Creative and energetic – Perfect for marketing, advertising, and content-driven brands.
Fourth, Supportive and empathetic – Great for customer service and HR applications.
To set this up, use clear instructions in GPT’s settings.
Example instruction for friendly and engaging:
"Use a warm, conversational tone. Responses should feel like a friendly chat while remaining professional. Avoid overly formal language."
Example instruction for authoritative and professional:
"Maintain a formal and precise tone. Use business-appropriate language and well-structured responses. Avoid casual expressions."
By setting clear personality traits, GPT will communicate in a way that feels natural for your brand.
Step 3: Refining Word Choice and Phrasing
GPT’s word choice plays a big role in brand consistency.
Here’s how to refine it:
First, decide on preferred terminology – If you use specific industry terms or jargon, ensure GPT includes them.
Second, avoid unwanted phrases – If there are words your brand never uses, tell GPT to avoid them.
Third, set phrase structures – If your brand prefers short, clear sentences, instruct GPT to follow that style.
Example instruction:
"Avoid corporate jargon. Use clear, easy-to-understand language. Keep responses structured with short sentences and direct messaging."
Refining word choice ensures consistency in communication across emails, social media, and customer support.
Step 4: Testing and Adjusting Responses
Once you’ve customized GPT’s tone and personality, test its responses to see if they align with your brand.
Try asking GPT business-related questions and evaluate:
- Does it sound like your company’s usual communication style?
- Is the level of formality appropriate?
- Are the responses engaging and clear?
If the responses feel off, refine the instructions.
For example, if responses are too formal, modify the instruction:
"Make responses sound more conversational and engaging. Avoid overly technical terms."
If responses are too informal, adjust to:
"Maintain a professional and polished tone. Avoid casual expressions."
Fine-tuning ensures GPT consistently reflects your brand’s voice.
Example Prompts for Refining Brand Voice
First, for a conversational brand, try this.
"Write a product description in a fun and engaging tone. Keep it light and easy to read."
Second, for a professional tone, try this.
"Generate a company announcement with a formal and polished tone. Keep it business-like and structured."
Third, for a friendly customer service approach, try this.
"Write a customer support response that is empathetic and reassuring. Keep it helpful and polite."
Fourth, for marketing copy, try this.
"Create a social media post that sounds energetic and persuasive. Make it attention-grabbing."
Fifth, for a legal or technical brand, try this.
"Summarize this document in a professional and precise manner. Use formal business language."
These refinements help GPT consistently match your brand’s voice.
Now it is time for your action task.
Step one. Define your brand’s tone and personality – Decide if it should be friendly, professional, or something else.
Step two. Write down a few key words and phrases that define your company’s communication style.
Step three. Update GPT’s instructions to match this style – Ensure it follows brand tone and avoids unwanted language.
Step four. Test GPT by asking it to generate emails, social posts, or customer replies and check if it aligns with your brand voice.
Step five. Refine and adjust until the responses feel natural and consistent.
By the end of this task, your GPT will communicate exactly the way your brand does.
Next time, we will explore how to use GPT for real-time decision support. We’ll cover how GPT can help analyze options, summarize key data, and assist in making business decisions.
