How I Trained ChatGPT to Write in My Clients’ Voices

Most people open ChatGPT and ask it to “write like me.”
Then they’re shocked when the result sounds like a corporate intern on their first day.

That’s because AI doesn’t know your client’s voice it knows language patterns.
If you want it to write like them, you have to train it like a ghostwriter.

Here’s exactly how I did it.

Step 1: Stop Asking for Style. Start Feeding Personality.

When I onboard a ghostwriting client, I don’t ask for adjectives like “inspirational” or “authentic.”
I collect receipts.

Old emails. Social posts. Podcast transcripts. DMs. Even voice notes.

Why?
Because words reveal personality patterns:

  • Sentence length = energy level.
  • Word choice = authority vs. approachability.
  • Rhythm = confidence vs. contemplation.

Once I have those, I drop them into ChatGPT and say:

“Analyze this text and describe their tone, rhythm, sentence structure, and emotion.”
