The Truth About AI Copywriting: How to Sound Human and Increase Sales

The AI Copywriting Epidemic

We have all read them. The LinkedIn posts that start with "In today's fast-paced digital landscape..." and end with "Let's navigate this journey together! 🚀"

This is raw, unguided AI output. It is wordy, soulless, and most importantly, it does not convert.

Good copywriting is about human psychology, rhythm, and emotion. AI models, by default, are programmed to be helpful assistants, not persuasive salespeople.

If you want to use AI to write landing pages, emails, or ads that actually make money, you must learn to override its default behavior.


3 Dead Giveaways of AI Copy (And How to Fix Them)

1. "The Thesaurus Vomit"

AI loves big words. Elevate, unlock, transform, navigate, delve, comprehensive.

The Fix: Force reading levels.

Add this to your prompt: "Write at a 6th-grade reading level. Use simple, punchy words. Never use the words: delve, unlock, elevate, or landscape."

2. The Flawless (Boring) Grammar

AI writes perfectly structured sentences. Humans don't speak like that. We use fragments. And start sentences with conjunctions. Like this.

The Fix: Command a conversational tone.

Add: "Write conversationally. Use short, choppy sentences. It is okay to start sentences with And or But. Use varied sentence lengths to create rhythm."

3. The Lack of Specificity

AI speaks in broad generalizations ("Our software saves you time"). Good copy is hyper-specific ("Cut your invoicing time from 4 hours to 12 minutes").

The Fix: Provide the raw data.

Never ask AI to "make up benefits." Feed it bullet points of raw facts, statistics, and customer quotes, and ask it to assemble them.


The "Style Mimic" Prompting Framework

The most powerful way to generate human copy is to train the AI on a human's voice.

Claude 3.5 Sonnet is currently the best model on the market for mimicking tone.

Step 1: The Voice Analysis

Feed the AI 3 pieces of your best writing (or writing from a copywriter you admire, like Gary Halbert or Justin Welsh).

Prompt:

Analyze the writing style, tone, sentence structure, and vocabulary of the provided text.

Create a comprehensive "Voice Profile" detailing exactly how this person writes.

Identify their typical hooks, transition phrases, and formatting habits.

Step 2: The Application

Save that Voice Profile. Whenever you need copy, use it.

Prompt:

Using the Voice Profile we generated above, write a 300-word promotional email for a new SEO course.

The core pain point is [X]. The solution is [Y].

Ensure it sounds exactly like the author from the Voice Profile.


The Cyborg Approach to Copywriting

The best copywriters in the world are not letting AI write their final drafts. They are using AI for ideation and structuring.

  • Angles: Ask AI to generate 20 different emotional hooks for a product (Fear, Greed, Vanity, Logic).
Objections: Ask AI: "Act as a skeptical buyer. Give me 10 reasons why you wouldn't buy this $500 course."* Then write copy addressing those objections.

Editing: Write a messy first draft yourself, full of emotion. Then ask AI: "Make this 20% shorter, punchier, and fix the grammar, but do not change the core tone."*

AI will not replace great copywriters. But a copywriter using AI will absolutely replace one who isn't. Master these advanced workflows at AIMasterclass.
