How to Write Marketing Copy with AI (Without Sounding Like a Robot)

Why Most AI Copy Sounds Terrible

Let's be honest: most AI-generated marketing copy is obvious. It overuses phrases like "game-changer," "leverage," "in today's fast-paced world," and "unlock your potential." It reads like a corporate press release written by a committee. And your audience can smell it from a mile away.

The problem isn't AI itself — it's how people use it. They type a vague prompt like "write me a sales email" and expect magic. What they get is generic output that could apply to any business in any industry. The solution? Better inputs, better editing, and a clear brand voice framework.

The Brand Voice Framework

Before you ask AI to write anything, you need a brand voice document. This doesn't have to be complicated — a simple one-page brief works. Include:

• Tone words: Three adjectives that describe how your brand sounds (e.g., "direct, warm, irreverent")
• Audience description: Who you're talking to and what they care about
• Words to use: Vocabulary that fits your brand personality
• Words to avoid: Corporate jargon, clichés, and phrases that don't fit
• Example sentences: 3-5 sentences that capture your brand voice perfectly

When you include this framework in your AI prompts, the output quality jumps dramatically. The AI has a clear target to hit instead of defaulting to generic corporate-speak.

The Prompt Engineering Approach

Great AI copy starts with great prompts. Here's a formula that works consistently:

1. Role: Tell the AI who to be ("You are a direct-response copywriter who writes in a conversational, no-BS tone")
2. Context: Provide background ("This is for a small business coaching brand targeting solo entrepreneurs making $50-200K")
3. Task: Be specific ("Write a 200-word email introducing our new workshop")
4. Constraints: Set boundaries ("Don't use the words 'leverage,' 'synergy,' or 'game-changer.' Use short paragraphs. Address objections about time commitment.")
5. Examples: Show what good looks like ("Here's an email that performed well: [paste example]")

Our AI prompt library has pre-built prompts for every type of marketing copy — emails, ads, landing pages, social posts, and more. Each prompt follows this framework and is ready to customize for your brand.

The Editing Process

AI gives you the clay; editing is where you sculpt. Here's a three-pass editing process that turns AI output into genuinely good copy:

Pass 1 — Voice Check: Read the copy out loud. Does it sound like your brand or like a robot? Replace any phrases that feel corporate or generic with how you'd actually say it to a friend.

Pass 2 — Specificity: Replace vague claims with specific details. "Grow your business" becomes "add $2,000/month in recurring revenue." "Save time" becomes "reclaim 10 hours a week." Specificity builds trust.

Pass 3 — Human Touch: Add one or two unexpected elements — a personal story, a contrarian opinion, a bit of humor, or a vulnerable admission. These are the things AI can't generate authentically, and they're what make your copy memorable.

Types of Copy AI Handles Best

Not all copy is created equal when it comes to AI assistance. Here's where AI delivers the most value:

• Product descriptions: AI excels at generating multiple variations of benefit-focused descriptions
• Email subject lines: Volume is the advantage — generate 20 options and pick the best
• Social media captions: Quick, repetitive content that benefits from batch creation
• Ad copy variations: Generate dozens of hook/body/CTA combinations for testing
• Blog outlines & first drafts: AI handles structure well; you add the expertise and personality
