Hi everyone 👋 Luis & Rui here with another practical guide on how to set up ChatGPT so it writes in your voice every time.

Follow the steps below and by the end of the hour ChatGPT will be able to draft emails, blog posts, social captions and support replies that sound like you wrote them yourself.

Let’s begin.

1. Understand the four parts of writing style

Your personal style has four moving parts:

Voice – how you sound (casual, formal, storyteller)
Tone – the feeling or attitude you bring (playful, sarcastic, hopeful)
Style – choices you make with words and sentences (short lines, no jargon, lots of detail)
Structure – how you order ideas (straight story, list, Q and A)

Knowing these labels will let you talk to ChatGPT in a way it understands.

2. Collect and prepare your sample texts

Pick three to five pieces of writing that feel the most like you.
Digital copies work best. If a piece is only on paper, type or scan it so you can paste the text.
If you have many short pieces (tweets, captions), bundle them into one long document and paste the bundle as a single sample.

Tip: Choose samples that match how you want ChatGPT to write in the future. If you plan to write product reviews, choose past reviews, not diary entries.

3. Use ChatGPT to analyse those samples

Open a chat in ChatGPT and keep all the work in that chat. Paste one sample and run this prompt:

Act like an expert writer. Your task is to read the text below and list bullet points for:
• Voice
• Tone
• Style
• Structure
Only return the four bullet lists.

[PASTE YOUR TEXT]

Repeat the paste‑and‑prompt loop for every sample. You will end up with several sets of bullet lists.

Now ask ChatGPT to merge and filter:

Combine the bullet lists you just made. Show only the traits that appear two or more times. Group them under Voice, Tone, Style and Structure.

The result is a clean list of traits that show up in most of your work. Copy that list to your notes app. This is your writing DNA.

4. Build a clear, short style sheet

ChatGPT performs best with a tight brief, so boil the DNA list down to a sheet of four to six lines. Example:

Voice: friendly teacher, plain words
Tone: upbeat, light jokes
Style: short sentences, no jargon, emojis allowed
Structure: hook > context > three steps > call to action

Keep it under 120 words if you can. Short is easier for the model to lock onto.
