Tame the Em Dash: 5 Simple Steps to Teach ChatGPT Not to Overuse the Em Dash

Introduction: Why This Matters Now

Many users have noticed that ChatGPT sometimes uses the em dash too often. Some writers want fewer em dash marks because they prefer clean, simple punctuation. Now you can guide ChatGPT to match your writing style.

Want to fix this quickly? Here are five clear steps you can follow right now.

Why Tell ChatGPT About Punctuation?

Punctuation shapes how writing feels. Too many em dashes can make sentences look dramatic or unnatural. Giving ChatGPT a style rule helps you get responses that sound more like your voice.

The update allows users to set writing preferences. That means you can teach the AI to follow rules like “avoid em dash” or “use short, direct sentences.”

Step 1: Open ChatGPT Settings or Personalization

1. Sign in to ChatGPT on your browser or mobile app.
2. Go to Settings or Personalization.
3. Look for Custom Instructions or Writing Preferences.

This section controls how ChatGPT writes for you.

Step 2: Add a Clear Style Instruction

Write a simple instruction in the box. For example:

1. Avoid using the em dash. Use commas instead.
2. Please don’t use the em dash. Write full sentences.
3. Keep punctuation simple. No em dashes.

Short, direct instructions work best.

Step 3: Test with a Short Prompt

Try a quick test:

1. “Rewrite this sentence without using an em dash.”

If ChatGPT follows the instruction, your setup is working.

If not, refine your instruction or make it stricter.

Step 4: Remind ChatGPT in New Chats

Each time you start a new conversation, add a small reminder:

1. “Use simple punctuation. Avoid the em dash.”

This reinforces your preference so the AI stays consistent.

Step 5: Edit and Train with Examples

If the AI still slips:

1. Paste the text.
2. Ask: “Rewrite this without using any em dashes.”

You can also share a short writing example of your style. The AI will follow similar patterns in future messages.

Helpful Tips for Better Results

1. Be specific. Tell the AI what to use instead.
2. Provide a small sample paragraph of your style.
3. Correct the AI when it slips. It improves the results.
4. Keep your instruction short and easy to understand.

Real-Life Example

A blogger named Arun disliked the heavy use of em dashes. He added a short instruction, “Avoid em dash. Use commas.” He also provided a sample paragraph. Within a few chats, the AI started matching his writing style. His editing time dropped a lot.

When You May Still Need a Human Edit

AI improves with your guidance, but long chats or complex tasks can cause small slips.

If you're writing something important like a blog or report, do a quick final check. This keeps your writing clean and professional.

Quick Style Checklist

1. Add your custom instruction.
2. Provide one example of your preferred style.
3. Remind the AI at the start of each new chat.
4. Ask for rewrites if needed.
5. Do a quick final edit yourself.
