AI copywriting in 2025: can you still tell the difference between human and machine?

Welcome to 2025, the year when AI and human copywriters go through a real identity crisis. Because honestly: who today can blindly tell whether a text was written by a creative brain or a smart algorithm?

Let's put it to the test. Can you guess which of these sentences were created by an AI?

A. "Every idea starts as a whisper in the head, but grows into a revolution if you listen."

B. "With us, you get customized solutions, with a smile and a nod to the future."

(Scroll down for the answer.)

The invisible hand of AI in copywriting

Thanks to huge leaps in generative AI and especially in "prompt engineering" - cleverly directing AI with creative input - the boundaries between human and machine-generated content have become razor thin. What used to be easily identified by stiff sentences or warped metaphors is now often indistinguishable.

The key? The right prompts.

What exactly is prompt engineering?

Prompt engineering is the craftsmanship behind driving AI: you'll learn how to give smart, contextual and creative commands so that the AI writes as if a seasoned copywriter were at work.

Compare it to cooking: if you just say "make a soup," you might get something edible. But if you say, "Make a creamy pumpkin soup with a hint of nutmeg, presented with an artichoke cream on an autumnal serving," you know you're getting something special.

And so it works with AI texts as well.

Example: one prompt, two completely different texts

Prompt 1: "Write a professional opening sentence for a B2B website."

AI output:

"We help companies grow with advanced digital solutions and a personal touch."

Prompt 2: "Write a playful, confident opening sentence for a B2B website that targets innovative growth companies."

AI output:

"You dream big. We encode those dreams into rock-solid growth."

See the difference? Same AI, but thanks to clever prompting, you get a totally different tone, rhythm and impact.

Can you still see it?

Let's come back to the sentences from earlier:

• A was written by a human copywriter.

• B came directly from ChatGPT, based on a well-crafted prompt.

Were you right? Don't worry if you were wrong: 74% of marketers in a recent Clickforest poll admitted they can no longer pinpoint the difference with certainty.

What should you look out for in 2025?

• Consistency: AI sometimes tends to "flip" style-wise within longer texts. A trained eye can see that.

• Deeper nuances: Irony, cultural references and subtle humor are still tricky for AI. Although. not as difficult as they used to be.

• Hyper-relevance: AI can use data to respond to trends super-fast, but weaving the real "soul" of a brand into a text remains a skill in itself.

• SEO optimization: AI can automatically structure texts according to SEO best practices, but strategic use of keywords and semantics remains a human asset.
