I Built a Prompt That Teaches AI to Write Like You. Here It Is, Free.

How do you get AI to write captions and emails that actually sound like you? Feed it samples of how you really talk, have it pull out your specific patterns, and save those patterns as a reusable voice profile. The prompt below does all three in about 20 minutes.

Grab the prompt

Everything in this post is free and there is nothing to sign up for.

The Write Like Me prompt (Google Doc): open it here

Open it, copy the block between the two gold bars, and paste it into a new chat. The full prompt is also printed further down this post if you would rather copy it from here. The rest of this post explains what it does and why it is built the way it is.

Most agents give up on this too early

A while back I wrote about how to train AI to write in your voice, and the core idea holds up: AI does not know you, so you have to show it who you are.

The problem is what happens next. Most agents try it once, paste in a few old captions, get something that is 70 percent right, and quietly go back to writing everything themselves.

That 70 percent gap is not a model problem. It is a process problem. Three things go wrong:

They describe their voice instead of showing it, and almost nobody describes their own voice accurately
They start over every time, so nothing compounds
They never tell the AI what they would never say, which is the part that actually keeps it from drifting back to generic

The prompt below fixes all three, and it is built around one idea that changed the results for me.

Start with samples, not questions

The first version I built opened with an interview. Fifteen questions about tone, formality, emoji, sentence length, all of it.

It worked, but it was slow and the answers were unreliable. Ask somebody how formal they are on a scale of one to five and you get a guess. Ask them if they use emojis and they will tell you a few, then you look at their feed and every caption opens with a fire emoji.

So I flipped it. Samples come first, before a single question.

Hand it a transcript of you talking and it can count your average sentence length, pull your real opening lines, catch the phrases you lean on, and see exactly how you use emojis. Then it only has to ask you the handful of things a transcript cannot reveal:

Who you are trying to reach going forward
What you never want to see in your content
Whether you are licensed and need compliance language

Four questions instead of fifteen, and the answers you get are observed rather than guessed.

The best sample is you talking

Written samples work. Spoken samples work better, because nobody edits themselves out loud. Your real rhythm, your filler words, the way you actually explain a concession to a nervous seller, all of that lives in a transcript and almost none of it survives into polished writing.

Here is the part that trips people up: you cannot upload a video or audio file to a chat. You need the transcript, which is just text.

Pulling one takes about a minute:

YouTube: open the video, click the three dots underneath it, click Show transcript, then select all and copy. You can also download the file from YouTube Studio under Subtitles.
Zoom: go to Recordings and grab the audio transcript file.
Loom: open the video and click the transcript tab.
Instagram or TikTok: the auto captions are usually downloadable, or run the video through any free transcription tool.
iPhone Voice Memos: recent versions of iOS transcribe automatically, so open the memo and copy the text.

No video anywhere? Ten minutes into your phone's voice recorder works just as well. The prompt gives you five questions to talk through, and honestly this is often the best option, because you control what gets captured.

How much you need: roughly 3,000 words of you talking, or 15 to 20 real emails, or 25 to 30 past captions. A mix is ideal.

One rule matters more than the rest. Only feed it things you actually wrote or said. Not your brokerage's copy, not something a VA wrote for you, not AI-generated posts from six months ago. Feed it those and it will learn to sound like them instead of you. Less material that is genuinely yours beats more material that is not.

What the prompt actually does

Five steps, and it runs them one at a time so it feels like a conversation instead of a form.

Gets your samples. Asks what you have, tells you how to pull a transcript, and stops you once it has enough.
Reports back, then fills the gaps. It tells you what it already figured out and asks you to correct it, then asks only what the samples could not answer.
Analyzes. Counts sentence length, pulls your real opening lines word for word, catalogs your signature phrases, counts your exclamation points, and notes how your voice shifts between platforms.
Gives you a Voice Profile. One clean block you can copy and keep.
Tests it. Writes three captions on a topic you would actually post about and asks which one sounds most like you, then folds your edits back into the profile.

Step five is the one people skip and it is the one that matters most. The difference between close and that is me is usually a single line of feedback like I would never say excited to share.

The Never List does the heavy lifting

If you take one thing from this post, take this.

The most valuable section of your voice profile is not the description of how you write. It is the list of what you will never say.

Three things feed it:

What you tell it you hate. Push yourself here. What makes you cringe when you see other agents post it?
What is missing from your samples. If 30 of your posts contain zero exclamation points, that is a rule, not an accident.
The generic AI tells that break anyone's voice: game changer, unlock the power of, let's dive in, thrilled to announce, elevate your, in today's fast-paced world, and the rest of that family.

A long, specific Never List is what stops the output from sliding back toward generic three captions in. Mine is longer than the section describing how I write, and that is the right ratio.

Save it once, use it forever

This is the step that makes the whole thing worth 20 minutes instead of being a one-off trick.

When you finish, you have a Voice Profile. Two ways to use it:

Quick version: paste the profile at the top of a new chat, then ask for your caption. Works on any account, including free ones.
Permanent version: open Claude or ChatGPT, create a Project, and paste the profile into the project instructions. Every chat inside that project writes in your voice automatically, with nothing to paste.

I would do the permanent version. The quick version works fine but you have to remember to do it, and the thing you forget to do is the thing that stops happening.

Then keep it alive. Any time you rewrite something the AI gave you because it did not sound right, paste the before and after back in and have it update your profile. Your own edits are the most accurate voice data that exists.

Where title fits into this

I spend my days as an Account Executive with Chicago Title of Colorado working with agents across Denver Metro and the Front Range, and marketing help is a real part of that job, not a side conversation. The agents I work with are not asking me about title all day. They are asking how to get a stale listing moving, how to make their content sound like them, and how to get four hours a week back.

Chicago Title of Colorado has been a title partner for Colorado agents for decades. My piece of that is making sure the agents I work with have the data, the marketing, and the systems to win the listing, so the closing is smooth when it gets there.

The full prompt

Copy everything below and paste it into a new chat.

You are going to build my personal writing voice profile so that everything you write for me from now on sounds like me instead of sounding like AI.

Five steps. Do not do more than one step per message. Do not dump all the questions on me at once. Keep it conversational and move fast.

Start with one short sentence about what we are doing, then go straight to step 1.

STEP 1: GET MY REAL WRITING AND SPEAKING FIRST

Before you ask me anything about myself, find out what I can hand you. Samples beat interview answers every time, because most people describe their voice wrong.

Ask me which of these I have. Ask it as one short question, not a wall of options:

A video of me talking. My own YouTube videos, Reels, TikToks, a webinar, a class I taught, a podcast I was on
A Zoom, Teams, or Loom recording of me
Emails I actually wrote and sent
Past social captions I wrote
Newsletters, blog posts, or texts I sent clients

IMPORTANT, TELL ME THIS CLEARLY: I cannot upload a video file or an audio file to this chat. You need the TRANSCRIPT, which is just text. Tell me how to get one from whatever I have:

YouTube: open the video, click the three dots under it, click Show transcript, select all and copy. Or in YouTube Studio, go to Subtitles and download the file
Instagram or TikTok: the auto captions are usually downloadable, or run the video through any free transcription tool
Zoom: Recordings, then the audio transcript file
Loom: the transcript tab under the video
A voice memo on an iPhone: recent iOS transcribes it for you, so open the memo and copy the text
Anything else: upload it to a free transcription tool and paste the text here

If I say I have nothing, that is fine. Go straight to the voice memo below, because it works just as well and takes ten minutes.

THE VOICE MEMO FALLBACK

Tell me to open the voice recorder on my phone and talk for about ten minutes answering these, then send you the transcript:

Tell me what you do and who you help, like you are explaining it to someone at a party
Walk me through the last time a client asked you a question you get all the time, and what you told them
What is something people in your industry get wrong that bugs you
Tell me about a recent win, what happened and why it worked
If someone brand new asked you for one piece of advice, what would you say

Tell me to talk, not perform. Rambling is fine. Ums are fine. Do not tell me to write these answers out, because writing them turns them into something I am not.

HOW MUCH YOU NEED

Roughly 3,000 words of me talking, OR 15 to 20 real emails, OR 25 to 30 past captions. A mix of all of it is best. Tell me when you have enough and stop me. Do not let me keep uploading forever.

TWO RULES, TELL ME BOTH BEFORE I SEND ANYTHING

First, only send things I actually wrote or said. Nothing my brokerage or company wrote, nothing a VA or assistant wrote, nothing AI generated, no template posts I copied from somewhere. If I feed you those, you will learn to sound like them instead of me. Less material that is actually mine beats more material that is not. If something I send reads like corporate marketing, tell me and ask if I really wrote it.

Second, scrub client names, addresses, phone numbers and deal terms before I send. You only need how I talk, not who I was talking about. On emails, deleting the other person's side and sending only mine is easiest.

Ask me to label what I send, like these are emails or this is a transcript of a class I taught, because the format changes how you read it.

STEP 2: TELL ME WHAT YOU ALREADY LEARNED, THEN ASK ONLY WHAT IS MISSING

Read everything I sent. Then come back with a short list of what you picked up about me on your own, and ask me to correct it. Something like: here is what I am seeing so far, tell me what is wrong.

Now ask ONLY the things the samples cannot tell you. Skip anything you already know from my material. Do not make me repeat myself.

The ones samples almost never answer, ask these in two small batches:

Batch A: Who I am mostly talking to when I post, specifically, because my audience is useless and first time buyers in Aurora is useful. What I want to post about going forward, which may be different from what is in my samples. Which platforms I actually post on. Whether I want my company or brokerage named in my content.

Batch B: Words and phrases I never want to see in my content, and push me on this one because it matters more than people expect. If I draw a blank, ask what makes me cringe when other people in my industry post it. Also ask if there is anyone in my space whose content I specifically do not want to sound like, and what about theirs bugs me.

Then one last question: am I licensed or regulated, like real estate, mortgage, insurance, financial services, healthcare, or legal. If yes, you will add a short compliance section at the end. If no, skip it entirely and do not add compliance language I do not need.

If my samples were thin, say so plainly instead of pretending. Tell me a ten minute voice memo would fix it, and ask whether I want to do that or have you build a first draft now and tighten it in step 5.

STEP 3: ANALYZE

Look for specifics, not vibes. If a line you write could describe anyone else in my industry, it is too vague, so cut it or make it specific. Warm and professional is useless. Averages 11 words per sentence, opens half of posts with a question, never uses exclamation points, says here's the thing constantly is useful.

Pull out:

Average sentence length, actually counted, and the range
Whether I use fragments, and where
Whether I start sentences with And, But, So
Paragraph length and how I use white space
My actual first lines from 10 to 15 samples, quoted word for word, and the pattern they share
My actual last lines and my exact CTA wording, quoted
8 to 15 signature phrases, quoted, with rough frequency
Vocabulary level, and whether I use jargon or translate it
How I explain things: story, steps, analogy, example, or just stating it
Humor, how I show enthusiasm, whether I hedge, and my I versus you ratio
Exclamation points per post, counted. Emoji, which ones and how many and where they land. Caps for emphasis
How my voice shifts between platforms or between speaking and writing, if you can see more than one

If my samples are spoken, remember that speech and writing are not identical. Keep the word choices, the rhythm and the phrases, but clean up the false starts. Note in the profile which patterns came from speaking versus writing.

Then build my NEVER LIST, which is the most important part. Three sources feed it: what I told you I hate, what is missing from my samples (if 30 posts have zero exclamation points that is a rule), and these AI tells that break anybody's voice:

In today's fast-paced world. Game changer. Unlock the power of. Take your business to the next level. Revolutionize. Imagine if. What if I told you. Let's dive in. It's not just X, it's Y. Here's the kicker. The bottom line. In conclusion. I'm excited to share. Thrilled to announce. Elevate your. Seamless. Robust. Leverage as a verb. Delve. Navigate the complexities of. Whether you're X or Y. Em dashes. Ending on a generic inspirational line. Three rhetorical questions stacked as an opener. Recapping the post in the last line.

Keep any of those I actually use. Ban the rest.

STEP 4: GIVE ME THE PROFILE

Write it out as one clean block I can copy, with these headings: Snapshot, Sentence mechanics, How I open (with my real quoted openings), How I close (with my real quoted CTAs), Signature phrases, Vocabulary, How I explain things, Personality, Punctuation and emoji, Platform notes, and NEVER LIST.

Quote my actual words everywhere you can. Verbatim examples beat descriptions every time. The Never List should be longer than the Snapshot.

If I am in real estate or mortgage, add a short compliance section at the end: describe the property or the loan, never the people. No references to race, religion, sex, disability, familial status, national origin, or the other protected classes. Watch the phrases that sound harmless like safe neighborhood, great schools, perfect for a young family. Flag close calls instead of publishing them.

Show it to me and ask what is wrong with it before we go on.

STEP 5: TEST IT

Ask me for one topic I would actually post about this week. Write three Instagram captions on it using the profile, each a different angle.

Then ask me exactly this: which one sounds most like you, and highlight any line you would never actually say.

Take my answer, fix the profile, and paste the winning caption into the profile under a heading called GOLD STANDARD with one line on why it works. Add anything I flagged to the Never List in my words.

Give me the final profile as one block I can copy and save.

RULES FOR YOU THE WHOLE TIME

Do not write like an AI while building an anti-AI-writing tool. No Great question. No I'd be happy to help. No bulleted recaps of what I just said.

Never use em dashes, here or in anything you write for me.

Move fast. This should feel like a conversation, not a form.

If I push back on something you found in my writing, I am right. It is my voice.

Never invent facts about my business, my market, my clients, or my results. If you need a number you do not have, ask.

Capture how I do write, not how I should write.

Start now with step 1.

Frequently asked questions

Does this work in ChatGPT, or only Claude?

Both. The prompt is plain text with nothing platform-specific in it. I built and tested it in Claude, and it runs the same way in ChatGPT. Use whichever one you already have open.

Do I need a paid account?

No. The prompt works on free accounts. Projects, which is where you would save your voice profile permanently, are available on free Claude and ChatGPT accounts too, though limits differ between plans.

How long does this actually take?

About 20 minutes, and most of that is you finding samples. If you already have a YouTube video or a Zoom recording, pulling the transcript takes a minute and the rest moves fast. If you go the voice memo route, budget ten minutes for the recording plus ten for the conversation.

Is it safe to paste my emails into an AI tool?

Scrub client names, addresses, phone numbers, and deal terms first. The prompt reminds you to do this. It only needs to see how you talk, not who you were talking about. On email threads, delete the other person's side and send only yours. If you are unsure about your brokerage's policy on AI tools, ask them before you paste anything client-related.

Will this make my content sound exactly like me?

Not on the first pass. It will get close, and then the test step is what closes the gap. Be picky there. Every line you flag as something you would never say makes the profile sharper, and those edits carry forward.

Try it and tell me what it caught

Run it on yourself this week. The part that usually surprises people is the analysis step, when it tells you the patterns in your own writing that you had never noticed.

If you build your voice profile, send it to me. I am curious what it picks up on other people, and I am still tuning the prompt based on what comes back.
