How to Create a Custom GPT AI Assistant That Sounds Just Like You

Let’s get into it, because today, we’re talking about how to clone your voice using AI and finally get some content support that actually sounds like YOU.

If you’ve ever said:

“I need help creating content… but I don’t want it to sound generic or robotic,”

then this blog post is your answer.

In this step-by-step guide, I’ll show you how to build a custom GPT (AI assistant) that’s trained to write captions, answer DMs, support your digital product buyers, and do it in your exact voice. 🙌

You don’t need tech skills. You just need ChatGPT Pro, a little prep, and this system.

Let’s build your digital clone, my friend!

What Is a Custom GPT (and Why Should You Care?)

GPT stands for Generative Pre-trained Transformer...a fancy way of saying:

“This AI can write, think, and talk like a human.”

But with Custom GPTs, you can teach it to talk like you.

That means you can:

• Upload your voice, tone, product details, and writing style

• Train it to answer questions, brainstorm ideas, write social posts, emails & more

• Use it like a virtual assistant, minus the salary or learning curve

This isn’t just automation, this is brand-aligned support.

What You Need to Create Your Custom GPT

Before we dive in, here’s what you’ll need:

1. ChatGPT Pro Plan for $20/month (this unlocks the custom GPT builder)

2. Your brand voice + mission – We’ll paste this in as part of your GPT setup

3. Optional: Past posts, captions, email samples, or product copy

Pro Tip: Have your “I help” statement ready.

Example:

“I help women over 50 build digital income streams with digital products, Canva, and AI tools, all without burnout.”

Step-by-Step: How to Build Your Own GPT (No Tech Overwhelm)

Let’s walk through this together.

Step 1: Go to the GPT Builder

1. Open ChatGPT (make sure you’re on the Pro plan)

2. Click “Explore GPTs”

3. Click “Create a GPT”

4. Choose “Configure”

Name it something fun and on-brand like:

1. Lady CEO Assistant

2. Boss Babe GPT

3. Digital CEO Genie

Step 2: Add Your Instructions

In the “Instructions” box, paste this prompt:

“You are a sassy, empowering digital business coach who helps women over 50 build profitable online businesses using digital products, Canva, AI tools, and simple marketing strategies. You write in a conversational, motivational tone with a dash of sass. Use short sentences, lots of encouragement, and keep things simple and clear. Do not use corporate language or jargon. Focus on results, action, and fun.”

Then add:

• Your mission

• Your product details (e.g., “I sell Canva templates, mini courses, and MRR products”)

• Common phrases you use (“Let’s gooo!” or “You got this, Lady CEO!”)

You can also upload past social posts, emails, or PDFs — to really train the voice.

Step 3: Save and Start Using It!

Once your GPT is created:

1. Bookmark it for easy access

2. Talk to it just like ChatGPT, but now it answers as YOU

3. You can keep editing the prompt over time to fine-tune your tone

How to Use Your Custom GPT in Your Business

This is where things get fun (and productive!).

Here’s how real business owners are using their GPT:

✔ Write Your Captions

Use prompts like:

“Write a 3-part Instagram series on overcoming content burnout in the voice of Michelle Spark.”

Pro Tip:

Your GPT can also draft:

2. Canva placeholder text

3. Welcome emails

4. Sales scripts

5. AND MORE

This is content support on demand and it’s always in your voice.
