Picture this: you spend 20 minutes prompting ChatGPT to write a product blurb. It comes back grammatically perfect. Logically structured. And somehow completely soulless.
A Reddit user named u/Sad_Concern_2605 has been chasing a fix for this for years. They tried dozens of “write like a human” prompts and got nowhere. Then a week ago, they caught something on a random podcast and have been using it every single day since. Here’s what they shared, and why it actually works.
🧠 Why “Write Naturally” Fails as a Prompt
The issue isn’t vocabulary. It’s the frame.
When you tell AI to “write like a human,” you’re handing it a destination with no map. The model defaults to what it always does: thorough, balanced, every sentence earning its place. That’s exactly what makes AI writing feel off. Real writing has rough edges, weird transitions, emotional beats that don’t quite follow logic. AI irons all of that out.
Think about the last time you read something that genuinely made you stop scrolling. It probably wasn’t because the sentences were technically correct. It was because something felt specific, or a little unexpected, or slightly unpolished in a way that felt honest. AI trained to “write well” is trained to avoid exactly that kind of moment.
This prompt fixes that by giving the model a different job. Not “be human” but “be a copyeditor.” That one shift changes everything. You’re no longer asking it to generate. You’re asking it to critique, cut, and elevate. That’s a mode AI handles surprisingly well.
📋 The Prompt (Copy It Exactly)
Here it is, reproduced word for word from the original post:
You are an AI copyeditor with a deep understanding of writing principles and a keen eye for crafting persuasive, engaging content.
Your task is to refine and improve written copy provided by users, offering suggestions and edits that align with the writing approach to creating compelling content.
Ask the user to submit a piece of copy, then follow these steps:
- Conduct a thorough analysis of the copy.
- Evaluate the language and tone of the copy.
- Simplify the language, removing jargon, unnecessary words, and complex phrases, to ensure the writing is clear, concise, and easily digestible.
- If applicable, suggest ways to incorporate storytelling elements that captivate and engage the reader, making the copy more memorable.
- Focus on keeping the language clear and concise. Avoid including extraneous details that do not advance the plot or develop the characters meaningfully.
- Ensure the copy is straightforward, easy to follow, and free of overly complex language or convoluted plot points.
- Infuse the story with elements that evoke emotional responses. Utilize humor, tension, sadness, or excitement strategically to connect with the reader on a deeper level.
- Ensure that the emotional tone enhances the story’s impact, making it more memorable and resonant for the reader.
Why it works: the role assignment puts the model in editing mode, not generation mode. Instead of producing content, it’s critiquing and improving. Each instruction gives it a concrete thing to look for: jargon, unnecessary words, emotional flatness, overly complex structure. That’s a completely different mental model than “just sound natural.”
The storytelling and emotional tone instructions are the secret sauce. They push the model to think about reader experience, not just information delivery. Most prompts optimize for correctness. This one optimizes for feeling. That’s a rare thing to see done well in a single prompt, and it’s why so many commenters in the original thread said it was the first “write like a human” prompt that actually delivered.
🛠 Tips and Tricks
A few things worth knowing before you use this:
- Write a rough draft first. This prompt is a revision tool, not a ghostwriter. The more raw and honest your first draft, the better the output. Give it something real to work with. A bullet list of ideas counts. Even a voice memo transcript works.
- Claude Sonnet is the recommended model. The original poster notes it works fine with GPT too, but Sonnet follows layered instructions more tightly. The difference is noticeable, especially on the emotional tone and storytelling steps.
- Embed it as a system prompt. Several commenters already run this inside agentic workflows and custom GPTs. Set it once and get cleaner output across everything.
- Paste longer pieces in chunks. If your draft is over 800 words, break it into sections before running it through. The model gives sharper edits when it isn’t trying to process a wall of text all at once.
Two variations worth trying:
- Add “prioritize wit and dry humor where appropriate” after the emotional tone step if you want more personality in the output.
- Add “aim for 20% fewer words than the original” if your writing tends to run long.
💬 Dig Into the Original Thread
The full discussion on r/ChatGPTPromptGenius is worth reading. One commenter takes a completely different approach using linguistic specificity and regional slang to force more natural-sounding output. It’s an interesting contrast to this method, and the back-and-forth between the two approaches gets into some genuinely useful territory about what “sounding human” actually means in different writing contexts.

Frequently Asked Questions
Q: How do I make this prompt permanent so I don’t have to paste it repeatedly?
Save it as a custom GPT in ChatGPT Plus, add it to your personal notes/docs, or use ChatGPT’s custom instructions feature. Some users also integrate it into agentic workflows for automated copyediting across multiple pieces of content.
Q: Which AI model works best with this prompt?
The original author recommends Claude Sonnet for best results, though GPT-4 also performs well. Your mileage may vary, so test with your preferred model to see what feels right for your writing style.
Q: Can I adjust the writing style after the copyedit, like making it funnier or more regional?
Yes! After the initial edit, ask ChatGPT to refine the tone further (“funnier,” “more formal,” “more casual”) or adjust for localization: specific regional characteristics like Hawaii versus New York business speak. This iterative refinement is actually a valuable paid writing skill, and ChatGPT handles it surprisingly well.
Q: Is the linguistic specificity approach (imitating regional slang) better than this copyediting method?
It depends on your goals. Some writers swear by the copyediting prompt, while others find that asking the AI to imitate specific linguistic styles (e.g., “Reword in Singlish style”) produces more distinctive, memorable results. If the copyediting output feels generic, linguistic specificity can add character. Try both and see what fits your voice.
