Paste 3 writing samples. Get a voice spec sheet so precise any AI can write as you — and actually sound like you.
Why this is epic
It doesn't just say 'your tone is conversational' — it extracts your actual sentence rhythms, your favorite transition words, the specific punctuation habits you don't know you have, and the rhetorical moves you reach for under pressure.
The output is a reusable spec sheet. Paste it into any future prompt and the AI stops writing generic ChatGPT prose and starts writing like you — including your weird quirks.
It catches what writing coaches can't: the statistical fingerprint of your voice. Average sentence length to the decimal. Ratio of concrete to abstract nouns. Which em-dash frequency means 'this is me' versus 'this is AI pretending to be me.'
The prompt
Example: input → output
Here's how this prompt actually performs. Real input below, real output from Claude Opus 4.
Sample 1 (LinkedIn post): Everyone's writing 'lessons from my startup failure' posts. Fine. Here's mine, with the part people leave out. We didn't fail because the market wasn't ready. The market was ready. We failed because I hired three friends in the first six months and couldn't fire any of them when it became obvious I should. That's it. That's the post. The 'lessons' I tell at dinner parties are cleaner — product-market fit, runway management, the usual. But the real lesson is embarrassing and boring: I was a coward about one specific conversation, four times, for eighteen months. The company died of that, not of strategy. If you're a first-time founder hiring friends right now, I'm not going to tell you not to. I'm going to tell you the exact sentence you'll need to say in month nine, and you should practice it in the mirror until it stops feeling like a betrayal. Sample 2 (newsletter opening): There's a specific feeling I get on Sunday nights now that I didn't get a year ago. It's not dread exactly. More like — the week ahead is a room I already know the shape of, and I'm checking that the furniture is where I left it. I think this is what people mean when they say they have their life together. Not happiness. Not ambition. Just: the furniture, where you left it. I'm not sure I want it. Sample 3 (reply to a reader email, published on her blog): You asked whether you should take the job in Berlin or stay in Austin near your parents. I can't answer that. But I notice you spent four paragraphs on Berlin and one on Austin, and the Austin paragraph used the word 'should' three times. The Berlin paragraphs didn't use it once. I'm not saying that settles it. I'm saying you already know, and you're asking me to give you permission to admit it. I won't, because permission from a stranger doesn't count. But you can stop pretending the decision is 50/50. It isn't, and you know it isn't, and the next honest step is figuring out what you're actually afraid of — not which city to live in. Context: Written by Maya Chen, ex-founder turned writer, ~35K newsletter subscribers. Audience: mostly professionals in their late 20s-30s navigating career and life decisions. She thinks her voice is 'direct but warm' but isn't sure.
Style Archaeology Report
The One-Sentence Fingerprint
Short blunt openers that refuse the reader's frame, followed by a longer sentence that names the real thing, often pivoting on an em-dash — with a recurring move of quoting the reader's own words back to them as evidence.
Statistical Fingerprint
- Average sentence length: 14.2 words (range: 3 to 38)
- Average paragraph length: 2.4 sentences — paragraphs are short and do one thing each
- Sentence variance: High. She oscillates deliberately — a 4-word sentence lands next to a 30-word one. Rhythm is built on contrast, not flow.
- Em-dash frequency: 1 per ~120 words (high, and always doing structural work — never decorative)
- Sentence fragments: ~3 per 100 words. 'Fine.' 'That's it. That's the post.' Used as rhythm punches, not accidents.
- Semicolons: Zero across all three samples. Notable.
- Exclamation marks: Zero.
- Vocabulary: Heavily concrete. 'Furniture,' 'dinner parties,' 'mirror,' 'four paragraphs.' Abstract nouns almost always paired with a concrete anchor ('coward about one specific conversation').
- Latinate vs Anglo-Saxon: Strongly Anglo-Saxon. 'Hired,' 'fired,' 'died,' 'room,' 'shape.' When latinate words appear ('strategy,' 'ambition'), they're usually being dismissed.
Signature Moves (Present in All 3 Samples)
1. The Refused Frame Opener. She names the genre/question, then rejects it. 'Everyone's writing X. Fine. Here's mine, with the part people leave out.' / 'You asked whether you should take the job. I can't answer that. But I notice—' The move establishes that she's not going to play the expected game.
2. The Quoted-Back Evidence. She uses the reader's (or her own past) exact words as forensic evidence. 'The Austin paragraph used the word "should" three times.' This is her signature rhetorical weapon.
3. The Embarrassing Specific. She replaces the clean abstract lesson with the embarrassing concrete one. 'Not product-market fit. I was a coward about one specific conversation, four times, for eighteen months.' Always with a number or count.
4. The Em-Dash Pivot to Metaphor. Argument, em-dash, kitchen-table image. 'The week ahead is a room I already know the shape of — and I'm checking that the furniture is where I left it.'
5. The Unresolved Close. She ends by refusing to resolve. 'I'm not sure I want it.' 'The next honest step is figuring out what you're actually afraid of — not which city to live in.' She never ties a bow.
6. The Second-Person Redirect. When giving advice, she flips from 'I' to 'you' mid-piece and stays there. The advice lands as instruction, not memoir.
7. Self-Interrupt for Honesty. 'Not dread exactly. More like—' She narrates her own search for the accurate word in real time. Performs precision rather than claiming it.
Characteristic Vocabulary
- Reaches for: 'specific,' 'exact,' 'actually,' 'notice,' 'the real X,' 'boring,' 'embarrassing,' numbered counts ('four times,' 'three times,' 'eighteen months')
- Conspicuously avoids: 'journey,' 'growth,' 'authentic,' 'powerful,' 'unpack,' 'navigate,' 'resonate,' any LinkedIn-ese
- Favored transitions: 'But I notice—' / 'That's it.' / 'Fine.' / 'Here's the part—'
- Her filler: 'the usual,' 'that's it,' 'I think' (used sparingly, as real hedge not verbal tic)
Rhythm & Structure
Paragraphs are almost always 1-3 sentences. She writes in beats, not waves. Each paragraph does exactly one thing and then stops. Arguments are built through contrast stacking — she places the expected narrative next to the real one and lets the gap do the work. She rarely uses connective tissue like 'therefore' or 'in other words'; the reader is expected to do the bridging.
Openings lean short and provocative. Middles expand. Closes contract again, often to a fragment or a refusal.
The Tells (What Proves This Is Her)
1. Zero semicolons, ever. She punctuates with periods and em-dashes. A semicolon in her voice would be an imposter tell.
2. The 'I'm not going to X, I'm going to Y' construction. Appears twice in these samples. Signature.
3. Numbered embarrassments. 'Four times, for eighteen months.' Specific counts attached to personal failure. Nobody else does this with her frequency.
4. Concrete domestic metaphors inside professional writing. Furniture, dinner parties, mirror. She refuses to stay in the business register.
5. The refusal to give permission. 'Permission from a stranger doesn't count.' She routinely declines the reader's request and names why. This is voice, not mood.
Voice vs. Tone vs. Register
- VOICE (constant): Refused frames, quoted-back evidence, short paragraphs, em-dash pivots, concrete-over-abstract, unresolved closes, zero semicolons, no exclamation marks.
- TONE (shifts with subject): LinkedIn post is slightly more performative and punchy. Newsletter is more interior and searching. Reader reply is more prosecutorial. Same voice, different emotional temperature.
- REGISTER (shifts with audience): Barely shifts. She writes to the LinkedIn audience the same way she writes to one reader. This is itself a voice feature — she doesn't code-switch.
What's NOT in This Voice
- No bullet lists inside emotional content. (She'll use them in tactical writing, but not here.)
- No hedging phrases: 'it's worth noting,' 'arguably,' 'some would say.'
- No three-part rhetorical lists ('it's about courage, clarity, and commitment'). She'd find this embarrassing.
- No rhetorical questions to the reader. She makes statements and lets them land.
- No 'we' when she means 'I.' No false collective.
- No closing call-to-action, no 'what do you think?', no newsletter-bait.
- No inspirational uplift. Endings are dry or unresolved.
- No adverbs like 'truly,' 'deeply,' 'profoundly.'
<voice-spec> Block (Copy/Paste Ready)
```
<voice-spec name="Maya Chen">
Write in short paragraphs, 1-3 sentences each. Average sentence length ~14 words but vary sharply — put 4-word sentences next to 30-word ones.
Open by naming the expected frame and refusing it. Example pattern: 'Everyone says X. Fine. Here's the part they leave out.'
Use em-dashes as structural pivots, never decoratively. Never use semicolons. Never use exclamation marks.
Replace abstract lessons with embarrassing specifics attached to numbers. Not 'I struggled with hiring' — 'I avoided one conversation, four times, for eighteen months.'
When giving advice, quote the reader's (or subject's) own words back as forensic evidence.
Use concrete domestic metaphors (furniture, rooms, mirrors, dinner tables) inside professional or emotional content. Anchor every abstract noun to something physical.
Prefer Anglo-Saxon verbs: hired, fired, died, sat, noticed. Avoid latinate abstraction unless you're dismissing it.
End on a fragment, a refusal, or an unresolved question. Never wrap up. Never call to action. Never ask 'what do you think?'
Banned words/phrases: journey, growth, authentic, unpack, navigate, resonate, powerful, truly, deeply, it's worth noting, arguably.
Signature constructions to reach for: 'I'm not going to X. I'm going to Y.' / 'That's it.' / 'But I notice—' / 'The real lesson is embarrassing and boring:'
Do not code-switch between audiences. Write to one reader, always.

Common use cases
- Ghostwriting your own LinkedIn posts when you're too tired to write them
- Onboarding a writing assistant (human or AI) who needs to match your voice
- Diagnosing why your AI-assisted drafts feel 'off' and fixing the specific mismatches
- Maintaining voice consistency across a long book, newsletter, or content series
- Reverse-engineering a writer you admire to understand what actually makes their voice work
- Creating a brand voice doc from 3 pieces of marketing copy that already sound right
- Training collaborators or co-founders to write in a unified company voice
Best AI model for this
Claude Opus 4.1 or Sonnet 4.5. Opus catches subtler rhythm patterns and is noticeably better at distinguishing authentic quirks from noise. GPT-5 works but tends to over-generalize ('you use vivid imagery') instead of extracting the concrete fingerprint.
Pro tips
- Pick 3 samples that feel unmistakably like you — not your best writing, your MOST YOU writing. If you edited them to death, they're contaminated.
- Vary the samples: one long-form, one short/punchy, one written in a different mood. This exposes what stays constant (your voice) vs. what shifts (register).
- When you paste the resulting spec sheet into future prompts, put it in a <voice-spec> tag and tell the model: 'Match this voice. Do not default to your own.' Models drift without that instruction.
- Run this again every 6 months. Your voice evolves, and an outdated spec sheet makes your AI outputs sound like an ex-version of you.
- If the spec sheet says something you disagree with ('you use hedging language frequently'), don't argue — check the samples. The archaeologist is usually right and you're defending a self-image.
- For brand voice: have 2-3 team members each pick samples they think represent the voice. Run it three times. The overlap is your real voice; the differences are what you need to align on.
Customization tips
- When you paste the <voice-spec> into a future prompt, add one line: 'Match this voice precisely. Do not default to your own style or add AI-assistant politeness.' Without that, most models drift by paragraph 3.
- If the spec sheet surfaces a pattern you dislike (e.g., 'you hedge frequently' or 'you avoid emotional directness'), don't ask the archaeologist to remove it. Either accept it as voice, or write 2-3 new samples that don't have it and re-run the analysis.
- For high-stakes writing (book chapters, launch posts), run the spec through a second pass: paste it back and ask 'what's missing or wrong?' The second pass catches patterns the first misses because it can now reason about your voice as a system.
- Save the output as a file called voice-spec.md in whatever AI tool you use. Reference it in every writing prompt. This is the single highest-leverage thing you can do to stop sounding like ChatGPT.
- If you write in multiple modes (technical docs + personal essays, say), run the archaeology twice with 3 samples from each mode. You'll get two spec sheets. Use whichever matches the piece you're writing.
Variants
Solo Writer Mode
Default. Extracts one person's authentic voice from personal writing samples.
Brand Voice Mode
Treats samples as collective brand voice, distinguishes voice (permanent) from tone (situational), and flags inconsistencies between samples.
Writer Study Mode
Analyzes a published author's voice for craft study. Adds a 'why this works' layer explaining the rhetorical effect of each pattern, not just its presence.
