Why Does ChatGPT Add Asterisks?

What Are Asterisks in ChatGPT?

Asterisks in ChatGPT are formatting markers. They tell apps how the text should look. ChatGPT uses a system called Markdown to add structure to its answers — a simple way to write text that looks plain but can be turned into bold, italic, headings, and lists by apps that understand it.

In simple words: ChatGPT is trying to make the answer easier to read. It uses symbols to mark what should become a heading, bold word, or list item. The issue is that not every app can turn those symbols into clean formatting.

What Do Two Asterisks Mean in ChatGPT?

Two asterisks around a word mean bold text. This is one of the most common things people see after copying from ChatGPT. The symbol **deadline** is ChatGPT's way of writing the word "deadline" in bold. Inside ChatGPT's own interface, the ** symbols disappear and the text just looks bold. The moment you paste it anywhere else, the symbols reappear.

ChatGPT almost always bolds labels like Timeline:, Budget:, Next Steps:, and Summary:. That's why you see double asterisks most often around section labels in emails, bullet lists, and structured outputs — exactly where the raw symbols look most out of place.

**Budget**
**Next Steps**
**Summary**

Why Do Asterisks Appear After Copy-Paste?

Here is the simple explanation of what happens every time you copy from ChatGPT and paste into another app:

1. 1
   ChatGPT writes in Markdown

   The answer uses symbols like **, *, #, and backticks to mark formatting.

2. 2
   The answer looks clean inside ChatGPT

   ChatGPT's own interface converts the Markdown into visible formatting. You see bold text, not asterisks.

3. 3
   You copy the text

   When you copy, the raw Markdown symbols are copied along with the words.

4. 4
   You paste into another app

   Gmail, LinkedIn, WordPress text mode, Word, and most form fields do not fully convert Markdown.

5. 5
   The raw symbols appear

   Instead of bold text, you see **bold text**. Instead of a list, you see * item.

I call this formatting pollution — when useful writing gets buried under symbols that were never meant to be seen. The table below shows exactly which platforms are affected and how.

My Real Gmail Test: Before & After

Here is an exact test I ran while building CleanTextTools. I asked ChatGPT to write a short project update email, copied the output, and pasted it directly into Gmail. The difference was immediate.

**Project Update**

**Timeline:** Complete by Friday
**Budget:** Approved
**Next Steps:** Review the draft

Project Update

Timeline: Complete by Friday
Budget: Approved
Next Steps: Review the draft

The left version looks like a code file, not a professional email. The right version is clean, readable, and ready to send. The words did not change at all — only the formatting noise was removed. That is the entire point: you do not need to rewrite your text to fix this problem.

Common Asterisk Problems I Have Seen

After testing AI text across Gmail, Google Docs, WordPress, LinkedIn, Microsoft Word, and Notion, these are the most frequent formatting problems. The frustrating part: the actual writing is usually good. The problem is never the content — it is the visible clutter around it.

Mistakes People Make When Removing Asterisks Manually

Most people try to fix the problem by hand. That works for one sentence. But it gets painful fast for longer text.

How to Stop ChatGPT from Using Asterisks

The easiest fix is to ask ChatGPT for plain text before it writes the answer. Don't just say "make it clean." Say exactly what you don't want. Here are four ready-to-use prompts:

Write your answer in plain text only. Do not use Markdown, asterisks, bold text, italics, headings, bullets, tables, backticks, hashtags, or special formatting of any kind.

Draft this email in plain text only. No Markdown, no asterisks, no bold text, no bullet symbols, no headings. Keep it ready to paste into Gmail.

Write this LinkedIn post in plain text only. No Markdown, no asterisks, no hashtags used as headings, no bold text, no special formatting.

Write this blog section in clean plain text. No Markdown symbols such as asterisks, hashtags, backticks, or code blocks.

How to Remove Asterisks from ChatGPT Text

You have four main options when you already have text with asterisks and need to clean it:

The fastest method for everyday use is the Remove ChatGPT Formatting tool at CleanTextTools. It runs entirely in your browser — no signup, no uploads, no rewriting. Paste your text, click Clean, and copy the result. Done in under five seconds. If extra spacing is the main issue, use the dedicated ChatGPT spacing fixer instead.

Step-by-Step Clean Copy-Paste Workflow

1. 1
   Ask for plain text before ChatGPT answers

   Add to your prompt: "Respond in plain text only. No Markdown formatting."

2. 2
   Check the answer before copying

   Scan for **, *, #, or backtick characters. If you see them, proceed to step 3.

3. 3
   Paste into CleanTextTools

   Go to cleantexttools.com, paste your text, and click Clean Text. No signup needed.

4. 4
   Copy the clean version

   Click Copy and move the clean plain text to Gmail, Google Docs, LinkedIn, WordPress, or Word.

5. 5
   Read it once before sending

   A final scan takes 20 seconds and prevents the embarrassment of sending a message that looks like broken code.

Does Claude or Gemini Do This Too?

Yes. This is not a ChatGPT-only problem.

In my own testing, I saw similar asterisk and Markdown formatting issues when copying text from ChatGPT, Claude, and Gemini into Gmail, Google Docs, WordPress, LinkedIn, and Microsoft Word. All three AI tools can produce structured Markdown output. All three create the same copy-paste problem when the destination app doesn't support Markdown.

The CleanTextTools formatting remover works with output from ChatGPT, Claude, Gemini, Perplexity, Copilot, Grok, and any other AI tool that generates Markdown-style text. It does not matter which AI you used — if the text has asterisks, it can clean them. For Google Docs specifically, use the Google Docs cleaner which handles Docs-specific artifacts too.

When Should You Keep the Asterisks?

You do not always need to remove them. Sometimes the asterisks are exactly what you want.

If your LinkedIn posts are showing asterisks from ChatGPT output, the Remove Asterisks from LinkedIn tool strips every asterisk symbol in one click — no install or signup required.
