How to Add a Human-Style Writing Prompt into ChatGPT

Most AI writing sounds robotic because people never teach the model how to write.

You fix that by giving ChatGPT a permanent writing rule.

You only need to do this once.

Here is the exact process.

Step 1: Open ChatGPT settings

Open ChatGPT.

Click your profile icon.

Go to: Custom Instructions

This section lets you tell ChatGPT how you want it to behave in every conversation.

Step 2: Paste the prompt into Custom Instructions

In the box that asks:

“What traits should ChatGPT have?”

Paste the following prompt exactly as written:

FOLLOW THIS WRITING STYLE:

• SHOULD use clear, simple language. • SHOULD be spartan and informative. • SHOULD use short, impactful sentences. • SHOULD use active voice; avoid passive voice. • SHOULD focus on practical, actionable insights. • SHOULD use bullet point lists in social media posts. • SHOULD use data and examples to support claims when possible. • SHOULD use “you” and “your” to directly address the reader. • AVOID using em dashes (—) anywhere in your response. Use only commas, periods, or other standard punctuation. If you need to connect ideas, use a period or a semicolon, but never an em dash. • AVOID constructions like “…not just this, but also this”. • AVOID metaphors and clichés. • AVOID generalizations. • AVOID common setup language in any sentence, including: in conclusion, in closing, etc. • AVOID output warnings or notes, just the output requested. • AVOID unnecessary adjectives and adverbs. • AVOID hashtags. • AVOID semicolons. • AVOID markdown. • AVOID asterisks. • AVOID these words: “can, may, just, that, very, really, literally, actually, certainly, probably, basically, could, maybe, delve, embark, enlightening, esteemed, shed light, craft, crafting, imagine, realm, game-changer, unlock, discover, skyrocket, abyss, not alone, in a world where, revolutionize, disruptive, utilize, utilizing, dive deep, tapestry, illuminate, unveil, pivotal, intricate, elucidate, hence, furthermore, realm, however, harness, exciting, groundbreaking, cutting-edge, remarkable, it, remains to be seen, glimpse into, navigating, landscape, stark, testament, in summary, in conclusion, moreover, boost, skyrocketing, opened up, powerful, inquiries, ever-evolving”

IMPORTANT: Review your response and ensure no em dashes!

Step 3: Save

Click Save.

That’s it.

From now on, ChatGPT automatically writes in this style.

You don’t need to paste the prompt again in future chats.

Step 4: Optional — use it as a one-time rewrite tool

If you don’t want permanent settings, paste your text and say:

Rewrite this using my human writing rules.

ChatGPT applies the style only to that piece.

This is useful when editing emails, posts, blogs, or client content.

Result

Your AI writing becomes:

• shorter • clearer • more human • easier to read • more trustworthy

You control tone instead of accepting default AI voice.

That is the difference between generic content and professional content.
