Six AI prompts that turn a single customer answer into homepage copy, ad lines, FAQ entries, subheadlines, and email subject lines — all in their words instead of yours. Works with Claude, ChatGPT, or any LLM.
Customers describe your business better than you can.
Every founder gets too close to their own product. You know what it does — so you describe what it does. Your customers don't care what it does. They care about the worry they had before they bought, and how it felt to be wrong about that worry.
The fastest way to write copy that converts isn't to be a better writer. It's to stop writing entirely for a minute and let a customer's own words become your headline, your ad, your FAQ, and your subject line. One open-ended answer is enough material for five headlines, ten ad hooks, three FAQs, and a week of email subjects.
You just need the question to ask and the prompts to run.
★ What's inside
The one question to ask customers
Prompt 01 · 5 homepage headlines
Prompt 02 · 10 ad hooks
Prompt 03 · 3 FAQ entries
Prompt 04 · 3 trust subheadlines
Prompt 05 · Voice-of-customer extract
Prompt 06 · 7 email subject lines
★ The Magic Question ★
Ask this one thing.
Every prompt below runs on the answer to this single question. Send it to recent customers via email, ask it on a call, or DM it to your warmest list. You only need one really honest reply to fuel the whole pack — three or four gives you a campaign.
What almost stopped you from buying — what hesitation did you have, and what made you do it anyway?
★ Three places to ask it
Post-purchase emailSend 7–14 days after the first purchase, when the value's landed but the memory of buying is fresh. One question, no survey form.
Customer call or interviewStart the call with it. Don't ease in. The most useful answers come when they're surprised by the question and have to think out loud.
Existing-customer DMPick 10 customers you have a real relationship with. DM the question directly. Replies feel like favors — and they almost always say yes.
The 6 prompts.
Copy each prompt into Claude, ChatGPT, Gemini, or whichever LLM you use. Replace [PASTE CUSTOMER ANSWER HERE] with the actual reply you got. Run all six on the same answer for a full campaign in 10 minutes.
You are a direct-response copywriter who specializes in pulling headline material from raw customer interviews. I'm going to paste a single customer's answer to the question "What almost stopped you from buying — what hesitation did you have, and what made you do it anyway?"
Your job: write 5 homepage headline candidates that:
1) Lead with their hesitation (not the product feature)
2) Use the customer's own words wherever possible — verbatim phrases beat polished ones
3) Are under 12 words each
4) Sound like a real person talking, not a brochure
5) Each take a different angle (problem-first, social-proof, contrarian, before/after, direct)
Format each as:
HEADLINE: [single line]
ANGLE: [one of the five types]
No commentary, no preamble.

Why this works
Most homepage headlines describe the product. The ones that convert describe the doubt that almost stopped someone from buying it. Forcing 5 different angles in one shot means you walk in with options to A/B, not a single bet to defend.
What to do with it
Drop your top 2 into a homepage A/B test for a week each. Whichever wins becomes the new baseline. The losers don't go to waste — they become subject lines and ad hooks.
★ Prompt 02 ★
10 ad hooks.
Output: 10 scroll-stoppersUse: Meta / Google / socialTime: 1 minute
Prompt
You are a performance-marketing copywriter who writes ad hooks for social-media feeds. I'm pasting one customer's answer to "What almost stopped you from buying us — what was your hesitation, and what made you do it anyway?"
Generate 10 short ad hooks (under 14 words each) that:
- Open with the objection itself, stated as the customer felt it
- Use their language — keep their slang, their hedging, their actual phrasing
- Mix three formats: 3 questions, 3 statements, 4 "I almost didn't ___ until ___" lines
- Each should work as the FIRST LINE of a Meta or YouTube ad (the scroll-stopper)
Format: numbered list, one hook per line. Tag each one [Q], [S], or [I] after a single space. No commentary.
Customer answer:
"""
[PASTE CUSTOMER ANSWER HERE]
"""
Why this works
Ad creative dies on the first 3 seconds. Hooks built from objection language stop the thumb because they sound like the comment section, not the brand. Mixing question/statement/almost-didn't formats gives you ammo for different ad placements.
What to do with it
Pick 3 hooks per ad set. Test as first-line text on Meta, as TikTok opening lines, or as Google Performance Max headlines. The "I almost didn't" format is the one most marketers skip — try those first.
You're writing the FAQ section for a small business. I'll paste one customer's answer to "What almost stopped you from buying — what hesitation did you have, and what made you do it anyway?"
Pull the 3 distinct hesitations from their answer (even if they only said one explicitly — read between the lines for the implied ones). For each, write an FAQ Q&A pair where:
- The QUESTION is phrased the way a hesitating customer would Google it or ask in a chat box (not how a marketer would clean it up)
- The ANSWER is 2–3 sentences max, addresses the hesitation directly, and where possible references what the customer in the source said helped them get past it
- No bullet points in the answers — keep them conversational
Format:
Q: [question]
A: [answer]
Customer answer:
"""
[PASTE CUSTOMER ANSWER HERE]

Why this works
The best FAQ section isn't "how do I reset my password" — it's the doubts your prospect is having right now, answered before they have to ask. Mining one real customer reply gets you closer to that than 100 internal brainstorming sessions.
What to do with it
Drop these on your sales page above the buy button and in your FAQ section. The "answer 3 distinct hesitations" framing is also gold for sales call scripts — give them to your team as objection-handlers.
You're a conversion copywriter. I'll paste a customer's answer to "What almost stopped you from buying — what hesitation did you have?"
Write 3 supporting subheadlines that go directly under a main headline on a landing page. Each should:
- Address one of the hesitations the customer mentioned (or implied)
- Be 12–20 words long
- Speak to the prospect at the moment of their worst doubt
- Use the customer's actual words at least once per subheadline
- Avoid jargon, superlatives, and exclamation points
Format: numbered list, no commentary. After each subheadline, tag with the specific hesitation it addresses in italics or brackets.

Why this works
The space directly under the hero is where most pages waste copy on a feature list. Use it to disarm doubt instead. A subheadline that names the prospect's exact worry — in their words — is more persuasive than three benefits stacked vertically.
What to do with it
Pair your winning Prompt 01 headline with the matching subhead from this output. Also drops cleanly into the opening line of email campaigns and the intro of landing-page sections.
★ Prompt 05 ★
Voice-of-customer extract.
Output: 5–7 stealable phrasesUse: All copy everywhereTime: 30 seconds
Prompt
You're a voice-of-customer analyst. I'll paste a customer's answer to "What almost stopped you from buying — what was your hesitation, and what made you do it anyway?"
Pull out:
- The 5–7 EXACT phrases or word combinations the customer uses (verbatim — no paraphrasing, no cleanup)
- For each, note what category of objection it represents (price, time, trust, fit, complexity, results, social/identity, other)
- Flag which 2 phrases are the most "stealable" — meaning they sound like something a real human would Google or say out loud, not marketing speak
Format:
PHRASE: "[exact quote]"
CATEGORY: [objection type]
STEAL THIS: [yes/no — only 2 yes flags total]
Customer answer:

Why this works
This is the prompt that upgrades all the others. The 2 "steal this" phrases are the ones you start using in every headline, every email subject, every ad. Verbatim customer language outperforms polished copy in every single A/B test we've ever shipped.
What to do with it
Save the output to a "voice-of-customer" doc and let it shape the next 90 days of writing. When you run Prompts 01–04 and 06 again on a new answer, the doc compounds — eventually you have a vocabulary list that's pure conversion gold.
You're an email copywriter. I'll paste a customer's answer to "What almost stopped you from buying — what was your hesitation, and what made you decide anyway?"
Write 7 email subject lines that:
- Address the same hesitation other prospects feel, before they have to ask
- Stay under 50 characters where possible (deliverability + mobile preview)
- Mix curiosity (3), direct objection (2), and social-proof framing (2)
- Use lowercase if it makes them feel more like a personal email — sentence case is fine, all-caps never
- No emoji in the subject line; leave them in the preheader if you must
Format: numbered list. After each subject, in parentheses tag with type [curiosity / objection / social-proof] and the character count.

Why this works
Subject lines are where most email programs leak the most money. An objection-led subject earns the open because the prospect feels seen. Mixing three types in one shot gives you fuel for a full sequence — welcome, nurture, abandoned-cart, re-engagement — from one customer reply.
What to do with it
Plug the 2 objection-led ones into your top abandoned-cart and welcome flows. Use the curiosity ones for newsletter sends. Save the social-proof ones for re-engagement campaigns to dormant subscribers.
The whole workflow.
Three steps. One customer answer becomes a full campaign of copy in roughly 30 minutes — most of which is just sending the question and waiting for the reply.
1
Ask the question
Send the magic question to 3–10 recent customers — email, DM, or on a call. Wait for one reply that's at least two paragraphs long. That's your fuel.
2
Run all 6 prompts
Paste the customer's answer into each prompt, one at a time. Run them in your LLM of choice. You'll have 5 headlines, 10 ad hooks, 3 FAQs, 3 subheads, a VoC list, and 7 subject lines in under 10 minutes.
3
Ship 2, A/B 2, save the rest
Pick 2 winners to ship live this week. A/B test 2 more against current copy. Park the rest in a doc you can pull from any time you need an email subject, an ad hook, or a hero line.
Tweaks by industry.
Three industries, three small changes to the master question and the prompts that get you sharper output.
E-Commerce
Products & subscriptions
Question swap: "What almost stopped you from clicking add-to-cart? What were you worried wouldn't be true when it arrived?"
When to ask: 14 days after first purchase via Klaviyo / Shopify Email — long enough to know if they love it, fresh enough to remember the doubt.
Best prompts to run first: Prompt 02 (ad hooks) and Prompt 06 (subject lines) — e-comm lives or dies on these two surfaces.
Pro move: ask repeat buyers AND one-time-only buyers separately. The hesitations are different, and so are the copy assets you'll write.
Service Pros
Trades, home services, consultants
Question swap: "What almost stopped you from hiring us? What were you worried we'd get wrong — and what made you trust us anyway?"
When to ask: within 7 days of project completion, by text or call. Skip email surveys — service customers don't fill them out.
Best prompts to run first: Prompt 03 (FAQs) and Prompt 04 (subheads) — service pros need objection-handlers on every sales page.
Pro move: when you get a really good answer, ask permission to use the customer's first name and city in your VoC quotes. "Sarah from Austin said it took her 6 months to call us" outperforms anonymous testimonials 4-to-1.
Creators & Coaches
Courses, coaching, programs
Question swap: "What almost stopped you from joining? What were you worried this would be — and what made you do it anyway?"
When to ask: at the end of week 2 of your program, when the early-quit risk has passed and the wins are starting. Reply rate is highest here.
Best prompts to run first: Prompt 01 (headlines) and Prompt 05 (voice-of-customer) — coach/creator landing pages need both.
Pro move: read the answers OUT LOUD before running the prompts. Your ear catches the verbatim phrases the LLM might smooth over. Mark the lines that made you pause — those are the headlines.
5 mistakes that kill the pack.
The prompts only work if you feed them the right answer and read the output the right way. Avoid these and the pack does the rest.
Mistake 01
Rewriting the question into "how could we improve?"
Improvement questions get you a product roadmap. The "what almost stopped you" question gets you marketing copy. Two different jobs. Don't blend them — the AI prompts depend on the doubt-language only the original question surfaces.
Mistake 02
Feeding it a one-sentence reply
"It was kind of expensive" isn't enough. If a customer answers short, ask one follow-up: "Tell me more about what you were worried it would be?" Two paragraphs of honest answer is the minimum input for prompts to find real material.
Mistake 03
Polishing the customer's actual words
The LLM might soften "I thought y'all were a scam" into "I was unsure about credibility." Don't accept it. Push back: "Use the customer's actual phrase verbatim." Their language is the asset; cleaned-up copy is the failure mode.
Mistake 04
Running prompts on fake/generated answers
Asking the LLM to "imagine a customer answer" then running the prompts on it gives you copy that sounds like every other landing page. The whole point is real friction language. Wait for the real reply. No shortcuts on the input.
Mistake 05
Shipping the first output unedited
The pack gives you 30+ candidate lines. Your job is to pick the 3–5 that hit hardest and ship those — not paste the entire list onto your homepage. The LLM does the heavy lifting; your taste does the choosing.
Mistake 06 · Bonus
Doing it once
This pack compounds. Run it monthly on a new customer answer and your voice-of-customer doc fills up with verbatim phrases that you can pull from forever. Each cycle gets sharper because you start recognizing patterns across customers.
