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

Welcome to 2025, the year AI and human copywriters are facing a real identity crisis. Because let's be honest: who can still blindly tell whether a text was written by a creative mind or by a clever algorithm?

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

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

B. "We provide tailor-made solutions with a smile and an eye to the future."

(Scroll down for the answer.)

The invisible hand of AI in copywriting

Thanks to significant advancements in generative AI, particularly in "prompt engineering" — the art of guiding AI with creative input — the lines between human and machine-generated content have become incredibly blurred. What was once easily identifiable by awkward sentences or clumsy metaphors is now often indistinguishable.

The key? The right prompts.

What exactly is prompt engineering?

Prompt engineering is the skill of guiding AI: you'll learn how to create smart, contextual, and creative prompts, so the AI writes as if a seasoned copywriter is at work.

Think of it like 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 autumnal tableware," then you know you're getting something special.

And that's how it works with AI texts too.

Example: one prompt, two completely different texts

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

AI output:

"We help businesses grow with advanced digital solutions and a personalized approach."

Prompt 2: "Write a playful, confident opening line for a B2B website targeting innovative growth companies."

AI output:

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

Can you see the difference? The same AI, but thanks to clever prompting, you get a completely different tone, rhythm, and impact.

Can you still see it?

Let's revisit 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 got it wrong: 74% of marketers in a recent ClickForest poll admitted that they can no longer confidently identify the difference.

What should you pay attention to in 2025?

• Consistency: AI can sometimes tend to shift styles within longer texts. A trained eye will spot that.

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

• Hyper-relevance: AI can use data to respond to trends extremely quickly, but weaving the true "soul" of a brand into a text remains a unique skill.

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

The limitations of AI copywriting in 2025

While AI is impressive, there are still challenges:

• Emotional depth: A human touch often remains necessary for genuine connection.

• Ethics and transparency: Who is responsible for AI-generated errors or misleading content?
