How to Write Sales Page Copy with AI That Doesn't Sound Generic

To write a sales page with AI that doesn't sound generic, give the assistant your customers' real words before you ask it for a single line of copy. Generic sales pages come from generic input. When you ask Claude or ChatGPT for "a sales page for my course" with nothing else, it fills every gap with the average of every sales page it has read. When you give it the exact phrases your buyers use, a one-page brief and one section at a time, it writes something that sounds like it was written for them.

This post is the whole process: collect, brief, structure, prompt, edit, test. It works with either assistant, on free or paid plans.

Why AI sales pages all sound the same

Read three AI-written sales pages and you will notice the same shape. A question headline. "Imagine a world where..." Three benefits in a row, each with two adjectives. "Whether you're a beginner or a pro." A guarantee called "risk-free" and a button that says "Transform your life today."

None of that is the model being lazy. It is the model doing what you asked: writing a plausible sales page. Plausible means average, and average is what sounds generic. The fix is not a cleverer prompt. It is better material and smaller requests.

Step 1: Collect real customer language first

Before you open the assistant, spend an hour collecting what customers actually say. You want exact phrases, not your summary of them.

Where to look:

• Reviews and testimonials of your product, or of competing products if you have none yet. Three-star reviews are the best: they name what people wanted and did not get.
• Sales calls and discovery calls. If you record them, search the transcripts for how people describe the problem before they knew your product existed.
• Emails and support tickets. The question people ask right before buying is an objection your page must answer.
• Community threads where your audience talks without a seller in the room.

Paste everything into one document with three headings: the problem in their words, what they want instead, and what almost stopped them. Keep the spelling and the slang. "I spend Sunday night dreading Monday's posts" is worth ten times more than "content creation is time-consuming."

If you use the objection-miner prompt from the ten prompts solo marketers reuse, this is where it fits: paste the reviews in and ask for objections, grouped, with the exact quotes underneath.

Step 2: Write a one-page brief

The brief is the context the assistant keeps coming back to. Write it yourself; it takes twenty minutes and it is the difference between your page and everyone else's.

Include:

1. Who it is for, in one sentence, and who it is not for.
2. The problem in two or three sentences, using phrases from your collection.
3. The offer: what they get, in concrete terms. Number of modules, pages, calls, templates. Price. Delivery.
4. The result a buyer can realistically expect, and in what time.
5. Proof you actually have: testimonials with permission, your own results, the number of people who bought. If you have none, say so; the assistant must not invent any.
6. The top five objections, from your collection.
7. The guarantee, exactly as you will honor it.
8. Voice: five phrases you would use and five you never would.

Store the brief and the customer-language document where you can reuse them. Both Claude and ChatGPT offer Projects on their free plans (checked September 2026): you upload the files once and every chat in that project can use them. Claude's free plan allows up to five projects; ChatGPT's free plan allows five files per project.

Step 3: The page structure

A sales page is a sequence of answers to the questions a buyer asks in order. This is the structure that works for most digital products and services:

1. Headline and subheadline. What it is and the result, for whom. Clear beats clever.
2. The problem. The situation in the reader's own words, so they think "that's me."
3. The offer. What they get, what it does, what changes. Specific parts, not vague benefits.
4. Proof. Testimonials, results, examples of the work. Real only.
5. Objections, as an FAQ. The five things that almost stopped past buyers.
6. The guarantee. What happens if it does not work, in plain words.
7. Call to action. One button, one action, and what happens after the click.

For a low-priced first product, the page can be short and some sections merge. The minimum viable funnel shows where this page sits between the opt-in and the delivery page.

Step 4: Prompt section by section

Do not ask for the whole page in one go. A single long request averages out every section. Ask for one section at a time, with the brief and the customer language attached, and ask for options rather than one answer.

The opening message in your project:

You are helping me write a sales page. The brief and the customer language are in the project files. Rules for everything you write: use the customers' own phrases where they fit; never invent testimonials, numbers or results; no words from my "never" list; short sentences; write the way I would say it on a call. Confirm you have read both files and list the three strongest customer phrases you found.

That last line is a check. If the phrases it picks are not the ones you would have picked, fix the files before you go further.

Then one section per prompt:

• Headline: "Write ten headlines for this page. Five should use a phrase from the customer language. Each under twelve words. No questions."
• Problem: "Write the problem section in 120 words, second person, using at least three exact customer phrases. No 'imagine'."
• Offer: "List what the buyer gets from the brief, then write one sentence per item on what it does for them. Concrete nouns only."
• Proof: "Here are my real testimonials. Pick the three that answer the biggest objections and write one line introducing each. Do not change their wording."
• Objections: "Turn the five objections in the brief into FAQ questions in the buyer's words, and answer each in under 60 words, honestly."
• Guarantee and CTA: "Write the guarantee exactly as the brief states it, in plain words, then three button labels that describe the action, not a feeling."

Choose the best option per section yourself, and paste it into your working draft. The assistant generates; you decide. That split is what keeps the page yours.

Step 5: The edit pass that strips AI tells

Once the draft is assembled, read it top to bottom with a checklist. These are the patterns that make copy sound machine-written:

• Warm-up openers. "In today's fast-paced world" and anything like it. Delete the first sentence of each section and see if it reads better. It usually does.
• Lists of three. "Faster, smarter and easier." Keep one, the true one.
• Stacked adjectives. "A powerful, comprehensive, easy-to-use system." Replace with one concrete fact.
• Hype words. Seamless, unlock, supercharge, game-changer, transform. Cut them all.
• Symmetrical sentences. "It's not just X, it's Y." Once per page at most.
• Abstract claims. "Save hours every week" becomes "write next week's posts on Sunday in forty minutes" only if that is true for your buyers.
• Invented specifics. Check every number and every result against the brief. If the assistant added one, delete it.

Then read the page aloud. The rules in our guide to AI video scripts that don't sound like AI apply to sales copy too: if a sentence sounds odd spoken, it reads odd on the page.

You can ask the assistant to help here as well: "Mark every sentence in this draft that uses a pattern from this list, and suggest a plainer version." Accept the fixes one by one; do not let it rewrite the page wholesale, or the tells come back.

Step 6: Test with real visitors

A sales page is a guess until people read it. Testing on a small site is simple:

1. Ask five people from your audience to read the page and tell you the one thing that made them hesitate. Their answers are your next FAQ entries.
2. Test one element at a time, starting with the headline, then the offer, because those carry the most weight. Keep each version live long enough to see a difference, not a day.
3. Treat the first sales as research. What people ask before buying goes into the objections section. What they say after buying goes into the problem section, in their words.

Every revision starts back at step 1: new customer language in, better page out.

The 15-minute version

If you want to start today:

1. Open a new project in Claude or ChatGPT.
2. Paste in ten reviews, testimonials or forum posts about the problem your product solves.
3. Ask: "List the ten most specific phrases these people use to describe their problem, exactly as written."
4. Write a five-line brief: who it is for, the offer, the price, the guarantee, and your proof.
5. Ask for ten headlines, each under twelve words, at least five using one of those phrases.

Pick one. You now have a headline written in your customers' language, which is more than most AI sales pages ever get.
