You know the feeling. You ask ChatGPT to write an email, and it comes back sounding like a corporate press release. "I hope this message finds you well." Nobody talks like that. Not you, anyway.
The fix is simple: teach it your voice once, then reuse it forever. Here is how, in about two minutes.
Step 1: Give it two samples of your writing
Pick two emails, posts, or messages you wrote that actually sound like you. Paste them into ChatGPT and say:
Here are two things I wrote. Learn how I write from these, and remember it for everything you write for me.
That is the whole trick. ChatGPT is good at matching patterns when you show it real examples instead of describing yourself in the abstract.
No samples handy? Answer these five questions instead:
- Formal or casual? Who are you usually writing for?
- Short sentences or long flowing ones?
- Do you use humor? What kind?
- Words or phrases you use all the time?
- Words or phrases you hate and never want to see?
Step 2: Make it write down your voice profile
Once it has your samples, ask for this:
Write up my voice profile: rhythm, word choices, tone, how I open things, how I close things, and a list of things to never do.
Save that profile somewhere you can find it again. A note in your phone works. This profile is the product. Everything after this is just reuse.
Here is what a finished one looks like:
# My Voice Profile
## Rhythm
Short sentences. One idea per paragraph. Rarely more than three paragraphs.
## Word choices
Plain words, contractions, occasional slang. Never uses "leverage" or "synergy."
## Tone
Warm but direct. Confident, never hedgy. Dry humor in asides.
## Openings
Jumps straight in, no greeting.
## Closings
One-line summary, then done.
## Signature moves
Rhetorical questions to make points. Parenthetical asides.
## Never do
No emojis. No exclamation points. No "hope you're well."
Read it back and fix anything wrong. If it says you are formal and you are not, correct it now. The profile only works if it is actually you.
Step 3: Use it every time
From now on, start writing requests like this:
Using my voice profile, write a follow-up email to a client who has not replied in a week.
Then check one thing after every draft: does it sound like you, or like a robot wearing your name? If something is off, tell ChatGPT exactly what to change and update the profile. It gets better every time you correct it.
One rule that saves a lot of awkward emails: if a request conflicts with your profile, say so out loud. Need a formal letter but your profile is casual? Tell ChatGPT which one wins this time. Do not let it silently guess.
Why this beats rewriting every draft
Most people use ChatGPT like a vending machine: put a prompt in, fix the weird output, repeat forever. A voice profile flips that. You do the setup once, and every email, post, and message after that starts from your voice instead of the default robot voice.
It works for more than email, too. Social posts, product descriptions, cover letters, even birthday messages. Anything where "sounding like me" matters.
