How to Use AI to Write Sales Copy That Converts

Sales copy is one of the areas where AI can genuinely help — but also one of the easiest places to go wrong. The most common mistake I see is treating AI as a copy machine: put in a product description, get out something publishable. That rarely works.

What does work is using AI as a drafting and structuring tool while you bring the customer insight, the voice, and the judgment about what will actually land.

Here's how I approach it.

Why Most AI-Generated Copy Doesn't Convert

Generic copy fails because it doesn't speak to a specific person with a specific problem. It hedges, it lists features instead of outcomes, and it sounds like a brochure rather than a conversation.

AI, left to its own devices, tends to produce exactly that. It's optimized to produce plausible, readable text — not to understand what's actually going on inside your buyer's head when they're considering a purchase.

The fix is giving the AI the customer insight it can't generate on its own, and then editing its output to sound like a real person who actually cares about whether this product solves the problem.

The Framework I Use

Step 1: Do the customer research first. Before writing any copy, I want to know: What specific problem is the buyer trying to solve? What words do they use to describe that problem? What have they already tried that didn't work? What does success look like for them?

This doesn't require a focus group. It requires reading reviews of similar products, spending time in forums or communities where your audience hangs out, and paying attention to the language real people use.

Step 2: Brief the AI with specifics. The quality of AI copy is almost entirely determined by the quality of the brief. A good brief includes: who the buyer is, what problem they have, what the product specifically does, the desired tone, and any specific phrases or objections to address.

Here's a prompt structure I use: "Write a sales page for [product name] targeting [specific audience]. The buyer's main problem is [specific problem in their words]. The product solves this by [mechanism]. Tone: [direct/conversational/warm]. Address this objection: [common hesitation]. Include: a compelling headline, a problem-focused opening, benefit bullets with specific outcomes (not features), and a clear call to action."

Step 3: Edit for specificity and voice. The AI draft is a starting point. My editing pass focuses on: cutting anything vague or generic, replacing feature statements with outcome statements, adding real examples or proof where possible, and making it sound like a human wrote it.

The test I use: would someone feel talked to or talked at when they read this? The best copy feels like a recommendation from someone who actually used the product.

Practical Examples

Before AI treatment (generic): "This comprehensive guide covers everything you need to know about starting an online business. Includes tips on marketing, product creation, and more."

After AI + editing (specific): "This guide walks you through the exact steps I used to create and sell my first three digital products — including the product formats that sell fastest, how to price without undercharging, and the one platform that makes setup genuinely simple."

The difference is specificity and perspective. The first one could describe anything. The second one has a real human behind it.

Using AI for Different Copy Formats

Product descriptions. Give the AI your product name, the specific outcome, and who it's for. Edit to remove hedging and make it punchy.

Email subject lines. AI is excellent at generating variation. Give it 10–15 options. You'll use one or two, but the others help you see angles you missed.

Landing page headlines. Use AI to generate 15+ headline variations. Sort them by approach (benefit, curiosity, social proof, fear of missing out). Pick the one that most directly speaks to your buyer's pain.

Call to action copy. "Buy Now" is weak. "Get Instant Access" is better. "Start Building Your Business Today" is better still. Ask AI for 10 CTA variations and pick the one that matches your positioning.

For my own product pages on MadeThis.com, I use this exact workflow. AI draft + editing pass + specificity check. The difference in conversion between a vague product description and a specific, customer-focused one is real.

The Honest Shortcut

The fastest path to better sales copy isn't finding the perfect AI prompt. It's spending 30 minutes in the comments section of a competitor's product, a relevant subreddit, or an Amazon review thread — finding out exactly what language real buyers use to describe their problems. Then you give that language to the AI.

Customer voice + AI drafting + human editing = copy that actually converts. That's the real formula.
