An interactive Claude prompt that runs a four-phase process — interview, content analysis, voice profile build, then test-and-refine — until the agent can write anything in your voice without it feeling like AI. Block 30–60 minutes and have a few samples of your real writing ready before you start.
Step 1 — Personalize the prompt
Only four fields. The interview itself is where the real work happens — these just make the agent address you by name and ground its questions in your market. Leave anything blank you don't want to specify.
Step 2 — Copy the prompt and paste it to Claude
Yellow = unfilled. Green = your value.
Important: this prompt kicks off an interactive session. After you paste it, Claude will start the interview with one question and wait for your answer. Don't try to answer all the questions in your first message — go one at a time the way Claude asks.
Step 3 — What happens after you paste it
Phase 1 — Interview (15–30 min)
Claude asks questions one at a time across five blocks: identity and positioning, tone and personality, experience and stories, communication style, contrarian thinking. Wait for each question, answer it, then it asks the next. Expect Claude to push back if your answer is vague — that's the prompt working. Don't pre-write your answers, don't try to look polished, just talk.
Phase 2 — Content analysis (5–10 min)
Claude asks you to paste 3–5 social posts, 2–3 emails or texts, 1 listing description, and any scripts or transcripts. Have these ready before you start. Don't clean them up — Claude needs the raw version to spot patterns.
Phase 3 — Voice profile build (5 min)
Claude produces a structured breakdown: core tone, sentence style, vocabulary patterns, banned phrases, humor usage, persuasion style, how you open and close, signature phrases. Copy this output and save it. This is the asset you'll feed into every other agent going forward.
Phase 4 — Test and refine (10–20 min)
Claude drafts four pieces in your voice: a Facebook post about the market, a listing description, a recruiting post, and a client message. You rate each from 1 to 10. Anything below a 9, Claude rewrites until it lands. Don't be polite — flag every off-voice phrase you spot.
Where to run it
Open a new Claude conversation — Cowork mode, claude.ai, the mobile app, or any agent you've built on top of Claude.
Paste the prompt as your first message. Claude will reply with one short acknowledgment line and then ask Phase 1, Question 1.
Answer one question at a time. Don't rush. The interview is the highest-leverage part — bad answers here cascade into a weak voice profile.
When you hit Phase 2, paste in your samples. When you hit Phase 3, save the profile. When you hit Phase 4, rate honestly.
Make the output reusable
The Phase 3 voice profile is the deliverable that matters long-term. Save it as voice-profile.md in a folder you'll remember, or paste it into a claude.ai Project's custom instructions, or drop it into the system prompt of any custom agent you've built.
Once it's saved, you don't need to run this whole process again for a while. You can paste the saved profile into any new Claude with: "This is my voice profile. Write/post/draft in this voice for everything in this conversation."
Re-run Phase 2 and Phase 4 every 6 months with fresh content samples. Your voice drifts — the profile should reflect how you sound now, not 12 months ago.
Tips that materially improve the output
Treat the interview like you're talking to a smart friend who's calling you on your BS. The prompt explicitly tells Claude to challenge vague answers — let it.
When Claude asks for examples, give actual examples. "I'm blunt" is useless. "I told a buyer last month their offer was a fantasy and we needed to come up 7% or stop wasting our time" is the kind of answer that builds a real voice profile.
For Phase 2, paste messy raw samples — your DMs, voice-note transcripts, draft posts you never published. The polished published stuff hides your actual voice under copy editing.
In Phase 4, if a draft is a 7 or 8, don't just say "8." Say why — which phrase felt off, which line sounded like a generic agent, which sentence you'd cut. The refinement only works if Claude knows what failed.
Don't end the session at "good enough." The prompt's end goal is "indistinguishable from you." A 9 or 10 means a friend reading the post wouldn't be able to tell it wasn't yours. Settle for that.
Quick troubleshooting
Claude tries to ask all the interview questions at once → reply: "One at a time. Wait for my answer before moving on." It'll comply.
Claude's drafts in Phase 4 still sound generic → your Phase 2 samples were probably too polished or too few. Paste in more, messier, more recent ones, and have Claude redo the profile.
Claude softens your tone in drafts ("you said you were blunt but I rounded the edges") → tell it explicitly: "Don't smooth me out. The rough edges are the voice." The prompt's "prioritize accuracy over politeness" rule covers this but sometimes needs reinforcement.
The conversation gets long and Claude starts forgetting earlier answers → ask it to re-print the Phase 3 voice profile and confirm it's still using it. If it's drifting, paste the profile back into the chat.
Privacy note: the interview will surface beliefs, hot takes, stories, and writing samples. Treat the resulting voice profile like business IP. Don't paste it into agents you don't trust, don't post the raw profile publicly, and be deliberate about what stories you share in Phase 1 — once they're in the profile they're in every piece of content the agent generates downstream.
Step 4 — Before you paste, run this checklist
Three things should be true before you start. Miss any of them and you'll either stall mid-session or end up with a weak profile.
1. You have 30–60 minutes blocked
This isn't a 5-minute task. The interview alone is 15–30 minutes if you're honest with your answers.
If you only have 10 minutes right now, don't start. The session works best uninterrupted — pause-and-resume sessions lose context and Claude has to re-anchor.
2. Your sample content is ready to paste
3–5 social media posts (Instagram captions, LinkedIn posts, Facebook posts — any platform).
2–3 emails or texts you've sent to a client or lead.
1 listing description you wrote.
Optional but high-value: any scripts, video transcripts, or voice-note transcripts. Voice notes especially — they're the closest thing to how you actually talk.
Don't polish them. Raw beats edited.
3. Copied with the button, not by hand
Use the Copy entire prompt button in Step 2. It captures the full text including the rules and acknowledgment instructions at the bottom.
If you select and copy manually, you'll likely miss the closing rules — which are the part that keeps Claude from sliding back into generic-agent voice.
The order, in one sentence
Fill in the four fields → click Copy entire prompt → open a new Claude conversation → paste as the first message → answer Phase 1 questions one at a time → paste samples in Phase 2 → save the profile after Phase 3 → rate drafts honestly in Phase 4 until you're at a 9 or 10.
