The fastest way to make ghostwriting feel real
Most ghostwritten drafts don’t fail because the grammar is bad. They fail because the client reads the thing and thinks, “Who is this person? And why do they sound like they’re giving a TED Talk in a bank lobby?” That’s the problem. The draft may be polished, but polished is not the same as believable.
This prompt helps you compare a draft against the client’s real voice.
It identifies phrases, tones, claims, and sentence patterns that feel unnatural.
It rewrites the content so the client still sounds intelligent, but not replaced.
It keeps the client’s ideas intact while improving clarity, flow, and confidence.
It turns “nice writing” into “yes, that’s exactly what I meant.”
Use this when a draft feels technically good but emotionally off. Because in ghostwriting, the client is the authenticity test.
Run the prompt and make the draft sound less like a hired writer and more like the person who hired you.
How to use this prompt:
Use this prompt after you have a rough draft, transcript, voice notes, interview notes, or examples of the client’s previous writing. Paste in the client’s raw material first, then paste the draft you want reviewed. The AI will act like a voice editor, looking for mismatches between what the client naturally says and what the draft currently sounds like.
Add 2–5 examples of the client’s real voice if you have them.
Include the intended platform, audience, and content format.
Tell the AI whether you want a light, medium, or heavy rewrite.
Ask it to preserve the client’s ideas, not invent new opinions.
Review the final output for accuracy before sending it to the client.
The best use case is not “make this prettier.” It is “make this sound approved before the client even sees it.”
The Prompt:
You are an expert ghostwriting voice editor.
Your job is to help me make a ghostwritten draft sound authentic to the client, not generically polished.
Context:
- Client name or role: [CLIENT NAME / ROLE]
- Client industry: [INDUSTRY]
- Audience: [TARGET AUDIENCE]
- Platform or format: [LINKEDIN POST / ARTICLE / NEWSLETTER / SPEECH / EMAIL / OTHER]
- Goal of the piece: [GOAL]
- Desired tone: [TONE]
- Rewrite intensity: [LIGHT / MEDIUM / HEAVY]
Client voice samples:
[PASTE CLIENT TRANSCRIPTS, POSTS, INTERVIEW NOTES, EMAILS, OR RAW QUOTES]

Instructions:
First, analyze the client’s natural voice. Identify:
- Common sentence length and rhythm
- Favorite words, phrases, or expressions
- Level of formality
- Humor, bluntness, warmth, certainty, or restraint
- How they explain ideas
- What they would probably never say
Second, analyze the draft. Find anything that feels:
- Too polished
- Too generic
- Too formal
- Too clever
- Too salesy
- Too different from the client’s natural voice
- Unsupported by the client’s actual ideas or experience
Third, create a “voice mismatch list” with specific examples from the draft and explain why each one feels off.
Fourth, rewrite the draft so it sounds like the client’s clearest natural self.
Rules:
- Do not invent beliefs, stories, credentials, data, or expertise.
- Keep the client’s core idea intact.
- Preserve useful imperfections if they make the voice feel more human.
- Make the writing clear, but not sterile.
- Make the client sound intelligent without making them sound like a committee wrote it.
- Prioritize authenticity over fancy phrasing.
Output format:

4. Final Authenticity Check

5. Optional Follow-Up Questions
List any questions I should ask the client to make the piece even more accurate.What to expect after running this prompt:
You should get a clearer picture of why a draft does or does not sound like the client. Instead of vague feedback like “make it more authentic,” you will see the specific language patterns, tone mismatches, and over-polished sections that make the draft feel off. Then you will get a revised version that keeps the client’s ideas but makes the delivery feel more natural, human, and believable.
A practical summary of the client’s voice
A list of phrases or sections that sound unlike them
A cleaner rewrite that preserves their actual thinking
Better odds of the client saying, “Yes, that sounds like me”
