How I Trained ChatGPT to Sound Like Me
It’s not just about tone—it’s about patterns, purpose, and punctuation.
Let’s be clear: ChatGPT didn’t magically start writing like me.
It didn’t read my Substack and say, “Ah yes, this girl loves ellipses, righteous snark, and abrupt plot twists.”
That’s not how it works.
If you want AI to sound like you, you have to teach it—on purpose.
🧠 What Voice Training Actually Means
Training AI to match your voice isn’t about uploading your soul into the cloud.
It’s about giving structure to your tone, habits, and phrasing so the model can mirror the patterns that matter.
Think of it like building a brand guide—but for your personal style.
✍️ Start With What You Already Write
If you’ve published content (newsletters, blog posts, social captions, long rants in your Notes app), you already have the raw material.
Pick 3–5 pieces that feel “most like you.”
Then look for patterns in:
Sentence length and structure
Punctuation style (Do you love em dashes? Hate exclamation points?)
Favorite phrases
Formal vs. casual tone
How you open and close
Whether your jokes are dry, loud, weird, or mean
🧱 Then Build a Simple Voice Summary
You don’t need a PDF. You just need a few clear statements like:
I use humor for clarity, not fluff
My tone is assertive, not aggressive
I like smart analogies and short punchlines
I write like I talk—but slightly edited for power
I use sentence fragments. On purpose.
You want to describe your voice in a way that AI can recognize and replicate, not just admire.
🔁 Start Prompting With Context
From here, you can give ChatGPT actual direction like:
“Write this in my voice: smart, sharp, confident, slightly snarky, with occasional short punchline lines for rhythm. Use em dashes, avoid exclamation points, and don’t over-explain.”
Do it consistently, and refine the outputs over time.
The more specific your instructions, the better the output.

TL;DR
If you want ChatGPT to sound like you, you need to give it something to work with.
Start with your writing.
Define your patterns.
Prompt with clarity—not vibes.
It won’t get it right on the first try.
But it will get better—if you get specific.
