A lot of people ask me, "Dean, how do you output so much content?"

My answer: AI.

I tell them I have my own GPT.

They look confused (as most Ai content sounds robotic, generic and takes a tonne of time to edit).

Then comes the question… “How long does it take to edit, so it sounds like you?”

My reply is: Not very long because I’ve taught it to write like me.

I see people saying “Steal my prompts” on LinkedIn all day long.

I really don’t need to.

I’ve built a system I can rinse and repeat.

One hour on ChatGPT will give me a week of content.

I don’t just give it a prompt and hope for the best.

I train it to write like me, think like me, and-if it had a pulse-probably drink coffee like me too.

So if you want ChatGPT to mirror your voice (or at least not sound like a corporate chatbot from 2009), here’s exactly how I do it.

Step 1: Capture your tone of voice

If you want ChatGPT to sound like you, you first need to define what "you" actually sounds like. That means creating a document that captures your writing style, tone, and personality.

What goes into this?

• Past blog posts, LinkedIn updates, and social media content.

• Emails and newsletters you’ve written.

• Any content that feels unmistakably “you.”

The goal is to build a document with at least 20,000 words of your writing or transcripts.. More is better, but this is a solid starting point.

Step 2: Create your tone of Voice Doc with ChatGPT.

Once you’ve created your tone of voice document, upload it to ChatGPT and give it clear instructions. Use a prompt like this:

Prompt:

You are an AI language model skilled at analysing text for writing style and tone of voice. I will provide a document containing examples of my writing, and your job is to analyse it and create a detailed "Writing Style and Tone of Voice Document." This document should include:

• An overview of my tone and style (e.g., conversational, direct, witty, etc.).

• How my tone varies across different platforms (e.g., formal for articles, casual for social media).

• Typical sentence structure and language choices I use.

• Common words and phrases I repeat.

• Formatting preferences (e.g., bullet points, short paragraphs, no fluff).

• How I connect emotionally with my audience.

Let ChatGPT process your writing and generate a style guide.

Step 3: Fine-tune with feedback

ChatGPT is good, but while it’s not perfect, it will reduce editing and allow you to scale your content output. That’s why you need to give it feedback.

Once it generates a few sample posts in your style, tweak them. Don’t just accept whatever it spits out-challenge it. Say things like:

• "I’d never use the word ‘utilise.’ Say ‘use’ instead."

• "This sentence is too robotic. Make it sound more natural."

• "I like this phrase, but I’d never say it quite like that-adjust it to sound more direct."

The more feedback you give, the better it gets.

Then, once you’re happy with it, take that and put it in a Google Doc. This becomes the anchor for your GPT.

Step 4: Train your custom GPT

If you want to take it a step further, create a custom GPT trained specifically on your writing. OpenAI allows you to upload documents and train ChatGPT to follow specific guidelines. Here’s what you do:

1. Upload your Tone of Voice Document.

2. Upload a document with examples of your best content.

3. Give it clear instructions what each document is for.

This way, every time you ask ChatGPT to generate something, it’s already working from a trained version of “you.”

This will mean your content output from here will more closely mirror your own voice and reduce down the edit time.

Step 5: Build a library of prompts for each type of content.

Now that you’ve trained ChatGPT to sound like you, use tailored prompts to get the best results. Here are some examples:

• Articles

• LinkedIn

• Video Scripts

• Tweets

What I like to do is create one longer piece (articles), then use secondary prompts to convert that into tweets, posts and scripts.

Spend the time making one big piece, then that becomes the source for everything else.

That way, an hours work can create 10x more content across all my socials.

The goal isn’t perfection-it’s consistency

ChatGPT will never be a perfect clone of you, but that’s not the goal.

The goal is to make it close enough that your content feels seamless, authentic, and recognisable.

This way, you reduce the time editing but 10x your output.
