Teach AI to write the way you talk,
so everything it drafts sounds like you.
“It doesn’t sound like me”
That’s the thing people say about AI writing, and they’re usually right.
If you’ve ever asked AI to write a caption or email, you probably know the feeling.
It’s grammatically correct. It sounds professional. And you wouldn’t say half of those things.
So you start changing a few words, and somehow you’re rewriting the whole thing, which is exactly what you were hoping to avoid.
Often, the missing piece is direction. You’ve told AI what to write about, but you haven’t shown it how you actually write - the words you use, how you explain things, whether you’re a little sarcastic or would never, under any circumstances, say “unlock your potential.”
We’re gonna give it that context.
In this guide, I’ll walk you through creating a voice profile - a short description of your writing style that you can share with ChatGPT or Claude whenever you want help writing.
It covers your tone, the rhythm of your sentences, your punctuation habits, and the words and phrases that feel natural to you. We’ll also point out the ones you’d never use.
Then we’ll test it and make a few adjustments so you can see what works.
The goal is a first draft that feels more like something you’d actually say, with less time spent fixing sentences that looked fine until you read them out loud.
Your ideas, opinions, and the final edit are still yours. You’re just getting a little help putting them into words.
You can use your voice profile for captions, emails, your bio, digital product creation, sales page, or whatever content you’ve been left writing from scratch at 11pm.
Five Steps at a Glance
through the steps
Your casual texts, a voice note, an email to someone you know well (real, unpolished writing, not your best writing).
Paste in one prompt with your samples, and get back a detailed description of how you write.
Using your voice profile, ask for three captions, then read them out loud, like they’re on a teleprompter.
Tell it what doesn’t sound like you, with specifics. Two or three rounds of revisions usually get there.
Somewhere you’ll find it again, so every draft from here starts with you. If you have Claude, you can save your voice profile to a project or skill.
Find three real samples
Take a few minutes to find at least three samples of your own writing. Choose ones that sound like you, even if they’re a little messy. You probably already have plenty to work with.
Your text messages. Start with a conversation with a friend or family member. Look for messages where you’re explaining something, telling a story, or sharing an opinion. A few sentences will be more helpful than “sounds good!”
A voice note. You can transcribe one you’ve already sent, or use the dictation feature in your notes app to talk about something you’re interested in. Imagine you’re telling a friend about it, and leave in the little asides and tangents.
An email to someone you’re comfortable with. Choose one you wrote without overthinking every sentence. A casual work email can work too, as long as it sounds like you.
An old post or caption. Look for something you wrote yourself and still feel good about (it could be from your personal account). It doesn’t need to have performed well, we’re just looking at how you write.
Choose samples where you weren't performing. When you write for an audience, you tidy yourself up, and what gets lost in the tidying is exactly what makes you sound like you. A mix works best, like a text, a voice note and an email.
Save your samples in a note or Google Doc. Add a short heading above each one, like "Text to a good friend" or "Email giving advice to a coworker." Keep the wording as is, but remove any names or personal details. Aim for at least a few hundred words in total.
Can't find enough to work with? The end of the prompt has a backup plan.

Build your voice profile
Open Claude or ChatGPT and paste this prompt into the chat, swapping the highlighted parts for your own words and samples.
I want you to learn how I write, so you can sound like me. What I want help writing: [captions, emails, newsletters…] Who I'm usually writing for: [your audience, or "still figuring this out"] Here are some things I wrote myself. They're casual and unpolished on purpose, because that's closer to how I sound than anything I'd write professionally. [attach your samples or paste them here] Study these and tell me how I write. Be specific and mechanical about it. Include: - Sentence length and rhythm. Do I run long or short? Do I mix them? - Paragraph length and how I move between ideas. - Punctuation and emojis. Exclamation marks? Dashes? Capitals for emphasis? Periods where other people would use a comma? - Contractions. Which ones, and how often? - How I open. How I close. - Words and phrases I reach for. - How I make a point: stories, examples, questions, or straight to it. - Whether I use humor, and what kind. Two rules: - Only describe what's actually in the samples, and quote the line that shows each habit. Don't describe how you think I'd like to sound. - If something appears only once, say so, rather than treating it as a habit. Some things in texts won't belong in what I'm writing, like typos or missing capitals. List those separately. Then write it up as a short profile I can paste into future conversations. Write it as instructions for writing as me, and end it with three short lines from my samples as examples. Add a short "Avoid" section to the profile with these defaults, unless my samples show I actually do them: - Hype words like "game-changer," "unlock," "elevate," "dive in" or "delve" - "It's not X, it's Y" and other dramatic reframes - Openers like "In today's fast-paced world" and closers like "I hope this helps" - Em dashes, lists of three, and summaries that wrap everything up at the end - More exclamation marks or emojis than I use - Sounding like an ad: hard sells, big promises, urgency or pushy calls to action, unless I ask for one - Stories, feelings or results about me that I didn't give you Last, ask me no more than three questions about anything you had to guess. If my samples are too short or too alike, tell me what would be helpful to add. If I don't have anything else, give me a few questions to answer in my own words instead, the way I'd text a friend, and use my answers as extra samples.
Mechanical, not flattering
Those two rules at the bottom of the prompt are important.
It describes what’s actually in your samples, not how it thinks you’d like to sound.
Anything that shows up only once gets flagged, instead of being treated as a habit.
“Your writing is warm, engaging, and authentic.”
That’s flattering, but it describes an aspiration rather than a habit, so it can’t help AI write like you.
“Uses periods where most people would use commas.”
“Rarely uses exclamation marks except when genuinely excited.”
“Opens with the point rather than context.”
Left to its own devices, AI will describe how you’d like to sound. What you want is mechanical, because that’s the part it can actually copy.
If the profile you get back reads like a compliment, while it's nice, it's not gonna be as useful for writing in your voice. You can tell it to be more specific and mechanical, and run it again.
If it asks you questions, answer them in your own words, then ask for the updated profile before moving on.
Test it
Take a few minutes to test the profile and find out how well it works by giving it this prompt:
Using the profile you just created for me, write me three Instagram captions about [something you'd post about, or anything you know well, like a recent weekend, a favorite recipe, or a tip you always give friends]. Then, separately, tell me which specific choices you made because of my profile. I want to see whether you actually used it or whether you just wrote normally and hoped. Flag anything you had to guess because the profile didn't cover it. Follow the Avoid section in my profile. If a caption needs a personal detail you don't have, leave a short note in [brackets] about what goes there, like [your brief morning routine], so I can fill it in.
That second paragraph is important because it makes the AI show its work.
Then read the captions out loud, as if they’re on a teleprompter. You’ll know very quickly if it feels natural or if it’s off.
If you’re not already posting on social, pick any topic you know well.
We're just testing how it sounds right now, not what it says.
Refine it
It's unlikely that it'll be just right the first time, but that's ok, because fixing it with specifics will improve the profile the most.
Look for words you'd never use, enthusiasm you don't truly have, places where it explains things too much, or sounds more formal than you are.
Anything that makes you cringe is information that you can use to improve it.
Give specific feedback like this example, then run it as many times as you need (2-3 rounds usually get there).
[I'd never say "dive in". There are too many exclamation marks. It's trying too hard to be upbeat. I don't explain things in that much detail. Keep the rhythm mixed. Use some short sentences for emphasis, but let longer sentences happen naturally when explaining an idea or telling a story. Don't make everything punchy. Keep paragraphs relatively short, usually one to three sentences. No more than one emoji per caption.] Update my profile to account for that. Tell me exactly what you changed, then give me the full updated profile so I can save the new version.
Swap the first section for your own feedback.
The more specific, the better.
Add those words explicitly to your profile’s instructions, and be specific. Instead of “avoid jargon,” list the exact words: “Never use [list of words].”
Your profile instructions might be too vague. Instead of “keep it casual,” try: “Use short paragraphs (3–4 lines max). Conversational expertise, like I’m sharing knowledge with a friend. Never use transitions like ‘Furthermore’ or ‘Moreover.’”
You probably need more writing samples. Add two or three more examples of the specific content type you’re creating, whether that’s social captions, emails, or course content.
Save it
Claude
Ask it to save your profile as a skill, and it'll write like you in any chat. Or add it to a project, so every chat in it shares your profile.
ChatGPT
Paste your profile into Settings → Personalization → Custom instructions so every chat uses it.
Too long to fit? Put it in a project’s instructions instead, and write inside that project. Skip “remember this”. Memory keeps a brief summary, not your full profile.
Any plan
Keep it in a note or a Google Doc, and paste it at the top of any chat when you want something in your voice.
Here's how I write: [paste your profile]. Now create [type of content] about [subject].
I actually use both ChatGPT and Claude, for slightly different tasks. I appreciate ChatGPT for basic brainstorming, giving me feedback, and improving my copy.
I love Claude because it thinks through complex tasks with me. When I’m planning something, it asks the questions I didn’t think to ask, spots what I’ve missed, and tells me when an idea won’t work instead of just agreeing with me.
I use it in Cowork, where it can work right inside the apps I already use, like Canva, Google Drive and my email, so I’m not copying and pasting between tabs all day.
And a Claude project keeps your voice profile next to everything else about your business, so every draft starts from all of it instead of a blank chat.
Free Claude is good to start, and it can already connect to your other apps.
Claude Pro adds more usage, unlimited projects, Claude’s most advanced model, and Cowork, which helps once you’re writing or creating for your business most days.
Tips for continued improvement
Give it new samples. When you write something you’re happy with, paste it into a chat (with your profile if you have it saved somewhere else) and tell it to “Add this to my voice profile as an example, and update anything it changes.” Real writing teaches it more than any description ever will.
If a draft comes back wrong, tell it what’s off and ask it to update your profile, like you did in Step 4. Then everything it writes will improve.
Used AI for a while?
- Check your samples. Skip anything AI helped you write, even if you edited it. Otherwise your profile learns AI's voice instead of yours.
- Replace old tone instructions. If you've saved some before, like ChatGPT's custom instructions or a Claude style, swap them for your profile, so the two don't pull in different directions.
- Use what you've already taught it. If memory is on, run this after your profile is done.
If you remember feedback I've given you about my writing in past chats, like words I've banned or things I said sounded wrong, list them. Add the ones that fit to my profile's Avoid section. Don't change how the profile describes my writing; that only comes from my samples. Then give me the full updated profile.
It only moves your old corrections into the Avoid list.
How you write still comes from your samples.
Your writing
sounds like you again
You did it! You have a voice profile, and from now on, everything AI drafts for you starts from how you actually sound. Honestly, it's what I use most for captions, emails, and other content.
Now that your writing sounds like you, the next questions tend to show up pretty quickly:
What do I post about that people actually want?
And how do I turn that into an actual business?
That's where most people get stuck, and it's the reason I'm building
The Business Build™
It takes what you already know and turns it into a working digital business: the product, the audience, the store, the branding, the emails, and the social content, in the right order, with Claude speeding up the entire process.
You don't need an audience, a tech background, or even an idea yet.
Join the waitlist, and you'll be the first to hear when the doors open.
Everyone on this list will get the founding (discounted) price. I’m excited to see you there!
P.S. The Business Build™ uses the voice profile you just made, so you're already a step ahead 👏
