In today’s episode, let’s talk about improving your writing style training with generative AI.

One of the problems you’ve probably noticed when asking generative AI to imitate your writing style is that it does a half-ass job. The reason for this is twofold.

First, most people provide a writing sample and say, “Mimic my writing style,” without defining what aspects to imitate. Writing style is an umbrella term—it includes many elements:

  • Language tone
  • Technicality
  • Sentence structure and syntax
  • Figurative language
  • Rhythm and pace
  • Sound patterns
  • Rhetorical patterns
  • Voice
  • Word economy and lexical choices
  • Descriptive language
  • Punctuation (some people love em-dashes)
  • Emotions and mood
  • Consistency
  • Paragraph structure
  • Intertextuality and analogies

When you say, “Mimic my writing style,” you don’t give generative AI enough specifics to understand what that even means. That’s part of why it’s not a great instruction.

Second, language choice matters. If you want AI to truly capture your writing style, you can’t feed it only your work writing—your professional, nonfiction content.

Consciously or not, our work writing tends to be stilted. We follow real or imagined guidelines about “professional” writing. Phrases like “Per my last email” or “Circling back on this” appear in emails but rarely in casual conversation.

Imagine hanging out with friends at a bar or pickleball club—would you say, “Circling back on the thing?” No, unless you’re being sarcastic. Outside of work, we write more naturally, casually, and informally.

Open your text messages—how many “Per my last message” texts do you have with friends? Probably none (unless it’s sarcastic).

If you train AI solely on work communications, you’ll get a dry, robotic version of yourself. You’ll look at the output and think, “That’s not me. Where’s the zing? Where’s my personality?”

Well, it’s not in the data you trained on—so AI won’t replicate it.

How to Fix This

If you have examples of writing you’ve done for fun—poetry, short stories, novels, or even unhinged group chats with friends—that material captures your real style.

Even in a professional setting, incorporating your outside-of-work voice adds missing spice. If you tell AI:

“Mimic my writing style—here’s how I write at work, and here’s a short story I wrote,”

…you’ll capture much more of who you really are.

An Exercise to Try

Write some fiction—short stories (1,000 words, about two pages). You don’t need to publish them or even show anyone. Fiction writing exercises your creative brain and teaches AI how to write like the real you.

“Dance like nobody’s watching. Write like nobody’s reading.”

When you feed AI both work and non-work writing and say, “Mimic my complete style,” you’ll be surprised how much better it performs.

That’s it for today. Thanks for tuning in—talk to you next time!
