Almost every discussion of AI writing voice for coaches treats voice as something you repair at the end. Generate the draft, then edit until it sounds like you again. That’s backwards, and it’s why so many coaches quit after two weeks of rewriting every paragraph by hand.
For a coach, your voice and how you come across to clients is crticially important. It’s all a prospect has to go on before they book a call with you. Your blog, your emails, and your posts are where someone decides whether or not you’re the person they trust to get in the trenches with them.
Why the default output sounds like nobody
Researchers at Cornell ran a study with 118 participants, about half American and half Indian, writing on culturally grounded topics with and without AI autocomplete. The suggestions pushed both groups toward Western defaults and thinned out their own reference points. The paper, presented at the CHI conference in Yokohama in April 2025, is called “AI Suggestions Homogenize Writing Toward Western Styles and Diminish Cultural Nuances.”
That study is about culture, not about coaching. But the mechanism behind it is the same one you fight every time AI-generated output comes back sounding competent… but generic. An AI model with no specific information about you reaches for the statistical middle of everything it has read. That middle ground is exactly where every other coach already is. And differentiation is the name of the game.
Coaches aren’t sitting this technology out, either. Constant Contact’s 2026 research on small business owners found 44% using AI to compose content, with “saving time” being the most useful benefit. That’s small businesses broadly rather than coaches specifically, but the direction is clear. The question isn’t whether you’ll use these tools. It’s whether what comes out the other side is recognizably yours.
What a voice profile actually is
A voice profile is a document about how you write, saved as a file you can paste into any AI tool as context. Not a prompt you retype every time. A reusable reference the model reads before it writes a single word.
But what goes into a voice profile is far more than just a list of banned words and phrases. It should also capture your tone and energy, language patterns like sentence length and contractions and punctuation, the phrases you reach for, and the words and phrases you never use.
Telling a model what you avoid corrects the output faster than telling it what you like, because generic writing is mostly made of things you’d never say.
Without that context, an AI editor smooths out your sentences, removes your quirky phrasings, and pushes everything toward some generic pattern. With a real voice profile in place, edits will come back sounding like a colleague who has followed you for years and knows your specific style.
The good news is that you don’t have to create your voice profile from scratch, and then spend months tweaking and fine-tuning it. That’s because our very own CEO, Chris Lema, has created a tool at YourVoiceProfile.com that teaches any AI exactly how you write. Your tone. Your rhythm. Your perspective. That means you can get AI-assisted content that actually sounds like you.
What Your Voice Profile delivers
Your Voice Profile is a $19.99 one-time purchase. You answer 13 multiple-choice questions covering tone, formality, sentence structure, and humor, then link 1-5 pieces of your own published writing. What you get back is a robust markdown document covering tone, rhythm, vocabulary, sentence structure, humor style, and platform adaptations. You can drop that file into Claude, ChatGPT, or any AI tool, either as a system prompt or as a context file.
Two parts of that are worth taking your time to get right.
First are your written samples. Thirteen questions on their own would produce a description of how you think you write, which is a different document from how you actually write. Most of us are poor witnesses to our own habits. Real, written samples are where the patterns you can’t see get surfaced.
The file format is the second. A markdown document isn’t locked into one company’s app. You can paste it into whatever tool you use today and whatever you switch to in two years, and you can hand a copy to a VA or a contract writer. That portability is worth the twenty dollars by itself.
Who should skip it
As helpful as Your Voice profile is, there are three types of people it’s not a fit for:
- You don’t already use an AI tool. The profile does nothing by itself. It’s context for software you have to be using in the first place.
- You only publish a few times a year. The math only works if you write often enough for the setup to pay itself back. Two posts a year doesn’t clear that bar.
- Your voice is still forming. If you’ve published a handful of pieces and none of them sound especially like you yet, a profile will faithfully describe writing that hasn’t found itself. Write more first.
The built-in alternatives, and where they stop
Every major assistant now ships something in this territory, and for many coaches one of these is enough.
- ChatGPT custom instructions. Free, and applied to every new chat. The standard field holds about 1,500 characters, which is a paragraph or two of guidance rather than a real profile.
- Claude custom styles. Lets you upload writing samples and build a style from them, which is the closest free equivalent to the sample-based approach.
- Gemini Gems. A saved assistant with persistent instructions and files you can attach for context, including documents from Drive.
All three share the same two limits. None of them walks you through what to describe, so you have to already know what makes your writing yours. And each one lives inside a single company’s app, so nothing travels with you when you change tools or hand the work to someone else.
Build a rough profile yourself in twenty minutes
If you want to test the idea before spending anything, you can get most of the way there on your own. Gather three to five pieces you’ve published that sound like you at your best, paste them into whichever assistant you already use, and run this:
Analyze the writing samples below and produce a reusable voice profile.
Cover each of these, quoting examples from the samples:
1. Tone and energy.
2. Sentence length and rhythm, including how often fragments appear.
3. Punctuation habits: dashes, colons, ellipses, exclamation points.
4. Vocabulary the author reaches for, and words the author clearly avoids.
5. How pieces open and how they close.
6. Recurring phrases that belong to this author.
7. An anti-pattern list: words and constructions that would signal the
writing is not theirs.
Write it as a markdown document addressed to an AI assistant, in the
second person, telling it how to write as this author. Be concrete
rather than general.Read what comes back and correct it. The model will get some of it wrong, and the corrections you make are the most valuable lines in the finished file. Then save it and paste it at the top of any session where you’re writing something that carries your name.
What a profile still can’t do
There are still a couple of limitations you should be aware of, although neither on is a reason to skip it.
Your voice drifts over a long conversation. The further you get into a single session, the more the model’s own defaults creep back in, and a long thread often ends up back in generic prose. Starting fresh sessions for new pieces of content solves most of that.
A voice profile can copy how you might tell a story. But it can’t come up with the story. Every specific detail that makes your writing worth reading — the situation you actually worked through, the thing your client actually said to you in the middle of a session — still has to come from you. A profile that produces eloquent paragraphs about experiences you never had is worse than no profile at all.
We’ve talked about this line before on this blog. The part of your work nobody can automate is the part where you’re actually present with another person, and that hasn’t changed. What has changed is how much of the surrounding work you have to do by hand, and whether the words that carry your name out into the world still sound like they came from you. That second part is what turns a casual reader into someone who books a call with you.
At the end of the day, it can’t hurt to try it. Teach the model your patterns once. Then see if it works well enough to help you reclaim a few hours of your valuable time for the work that only you can do.
