How to make ChatGPT write in your exact voice (not robotic AI voice)

I wish I knew this before!

In partnership with

Hey there,

You asked ChatGPT to write something for you. You get a response that is, overly formal. Corporate buzzwords. Sentences that sound smart but say nothing.

Nobody writes like that in real life. But ChatGPT defaults to it every single time.

Here's how to fix it. You teach ChatGPT to write exactly like you.

Not "in a casual tone." Not "friendly and conversational." Like YOU. Let’s see how to do that in this post.

The Problem With Generic Tone Instructions

Most people do this:

"Write an email about X. Use a casual tone."

ChatGPT interprets "casual" its own way. You get something that's sort of casual. But it still doesn't sound like you.

Because "casual" means different things to different people.

Your casual might be short sentences and no fluff. Someone else's casual might be emojis and exclamation points.

ChatGPT can't read your mind. You need to show it exactly what your voice sounds like.

The economy isn’t clearly breaking. But who would say it’s fine? GDP says one thing. Sentiment says another. Markets bounce up and down. Even the pros can’t agree on what comes next.

Here’s the thing. Most everyday investors often stick with what they know. Stocks. Bonds. Cash.

Few people understand one key principle. An investment is one decision. A portfolio is another.

Data suggests smart portfolios are built on different asset classes that don’t all react to the same forces.

There’s one that serious investors use to diversify that’s moved independently for decades. 

Priced globally. Finite supply. Protected from flash crashes.

The Voice Cloning Technique

Here's the method that actually works.

Step 1: Give ChatGPT 3 examples of your writing.

Find three things you've written. Emails. Social posts. Blog paragraphs. Text messages. Whatever.

They need to be in YOUR voice. Not something you wrote for work that had to sound professional. Your actual voice.

Paste all three into ChatGPT and say:

"These three examples show how I write. Analyze my writing style. What patterns do you notice in sentence structure, word choice, tone, and rhythm?"

ChatGPT will break down your voice. Sentence length. Vocabulary level. How you start paragraphs. How you transition between ideas.

Step 2: Turn that analysis into instructions.

Now tell ChatGPT:

"Based on that analysis, write me a set of style rules I can use in future prompts to make you write exactly like me."

ChatGPT gives you a list. Could be 10 rules. Could be 15. Whatever captures your voice.

Save those rules.

Step 3: Use those rules in every prompt.

From now on, every time you want ChatGPT to write something, paste your style rules at the top.

"Write an email about X. Follow these style rules: [paste your rules]."

The output will sound like you wrote it.

Real Example: Before and After

Let me show you what this looks like.

Generic prompt: "Write a LinkedIn post about why consistency matters more than perfection. Casual tone."

What you get: "Consistency is the key to success. While many people chase perfection, the reality is that showing up every day matters more. Small, consistent actions compound over time and lead to remarkable results. What's one thing you're being consistent with? Share in the comments!"

Sounds fine. But it doesn't sound like any specific person.

Advanced prompt with voice rules: "Write a LinkedIn post about why consistency matters more than perfection.

Voice rules:

  • Use short, punchy sentences. Mix in longer ones for rhythm.

  • Start with a direct statement. No questions in the opening.

  • Use 'you' and 'your' to speak directly to the reader.

  • Avoid corporate buzzwords like 'leverage' and 'key.'

  • No rhetorical questions that feel forced.

  • End with a period, not an exclamation point, unless it's genuinely exciting.

  • Write like you're texting a smart friend."

What you get: "Consistency beats perfection every time. You don't need the perfect post. You need to post. You don't need the perfect workout. You need to show up. The people who win aren't the ones with perfect plans. They're the ones who kept going when it got boring. Small things done repeatedly always beat big things done once. Stop waiting for perfect. Start now."

See the difference? Same topic. Completely different voice.

The 3 Voice Elements You Need to Define

If you don't have examples of your writing handy, you can manually define your voice. Focus on these three elements.

Element 1: Sentence structure

How long are your sentences? Do you use fragments? Do you vary length for rhythm?

Example instruction: "Mix short sentences (5 to 8 words) with medium ones (12 to 15 words). Use occasional one word sentences for emphasis. Never go over 20 words."

Element 2: Word choice

What level of vocabulary do you use? Formal or casual? Do you use contractions? Any words you avoid?

Example instruction: "Use simple, everyday words. Always use contractions (you're, don't, it's). Avoid words like 'utilize,' 'leverage,' 'synergy.' If a 10 year old wouldn't understand it, don't use it."

Element 3: Rhythm and flow

How do you start sentences? How do you transition? What's your pacing like?

Example instruction: "Start sentences with action words when possible. Use 'But' and 'And' to start sentences. Keep paragraphs to 2 to 3 sentences max. Create white space. Make it scannable."

Combine all three and you have your voice profile.

How to Store Your Voice for Reuse

You don't want to paste your voice rules into every single prompt. That's annoying.

Here's what to do instead.

Option 1: Use ChatGPT's custom instructions.

Go to settings. Find "Custom instructions." Paste your voice rules there.

Now every conversation uses your voice automatically.

Option 2: Create a saved prompt template.

Save your voice rules in a Google Doc or note app. Title it "My Voice Rules."

Whenever you need ChatGPT to write something, copy your template and add the specific task at the top.

Takes 10 seconds. Works every time.

Why This Matters More Than You Think

When ChatGPT sounds like ChatGPT, people tune out.

They've seen that style a thousand times. It signals "this was written by AI."

When it sounds like you? People engage. Because it feels real.

This matters for emails. Social posts. Blog content. Client communication. Everything you write.

The difference between sounding like everyone else and sounding like yourself is just better instructions.

The Reality Most People Miss

Getting your voice right takes one session. Maybe 30 minutes.

After that, every piece of content ChatGPT writes for you sounds like you. Not AI. Not generic. You.

That 30 minutes saves you hours of editing every single week.

Here's How to Skip The Setup

I've built prompts that already include voice customization frameworks.

You don't spend 30 minutes analyzing your writing. You answer 5 questions and get a voice profile.

Then you use that profile with any of the 10,000+ ChatGPT prompts in my bundle.

Right now it's $19.99. Goes to $97 in 48 hours.

P.S. The moment someone can tell you used AI is the moment you lost them. Make ChatGPT sound like you and nobody will ever know the difference. That's the entire point of using it well.
