What ChatGPT inserts into your text

ChatGPT formats every response in Markdown: **bold** asterisks, ## headings, em-dashes (—), curly quotes, and invisible zero-width characters (U+200B, U+FEFF). Paste into Word, Gmail, Notion, or a CMS and the raw syntax breaks your formatting. TextPurify strips all of it without touching your actual content.

Bold & Italic Asterisks

ChatGPT wraps key terms in **double asterisks** for bold and *single asterisks* for italic. Outside markdown-rendering apps these symbols appear literally.

**important point** → important point
#

Markdown Headings

ChatGPT prefixes section titles with ## or ### which appear as literal hash symbols when pasted into plain-text editors, email, or most CMSs.

## Introduction → Introduction

Em-Dashes

ChatGPT uses the em-dash character (—) as a stylistic separator. It causes layout issues in CMS rich-text fields, spreadsheet imports, and some email clients.

Smart / Curly Quotes

ChatGPT outputs typographic "curly quotes" instead of straight quotes. These break JSON strings, code, HTML attributes, and some CMS field validation.

"hello" → "hello"
👻

Zero-Width Characters

Invisible Unicode chars (U+200B zero-width space, U+FEFF byte-order mark) travel with copied ChatGPT text and cause broken word counts, search mismatches, and encoding errors.

Unicode Ellipsis

The single-character ellipsis (…) is not the same as three dots (...) and breaks string comparisons, CMS character limits, and feed validators.

Frequently Asked Questions

Why does ChatGPT text look weird when pasted?

ChatGPT is trained to format responses in Markdown for rendering in its own interface. When you copy and paste into a plain-text context — Word, Gmail, a CMS — the raw syntax (**, ##, —, curly quotes) becomes visible. TextPurify strips it before you paste.

How do I remove asterisks from ChatGPT text?

Paste your ChatGPT text into TextPurify and click Clean Text. The tool removes both bold (**text**) and italic (*text*) markers while keeping the words. You can also enable 'Remove asterisks' to strip every * character.

How do I remove em-dashes from ChatGPT output?

Enable the 'Dashes' option in Cleaning Options and TextPurify will normalise em-dashes (—) and en-dashes (–) to standard hyphens. The preset for ChatGPT has this on by default.

Does this work with GPT-4o and o3 outputs?

Yes — all ChatGPT model variants (GPT-3.5, GPT-4, GPT-4o, o1, o3) produce the same Markdown-formatted output. TextPurify cleans any version.

Is my text sent to a server?

Never. All cleaning runs 100% in your browser using JavaScript. Your text never leaves your device.

What is the difference between Strip Markdown and Remove Asterisks?

Strip Markdown intelligently handles **bold** and *italic* by removing the syntax markers while keeping the enclosed text. Remove Asterisks is a blunt pass that deletes every * character — useful if you just want bullet-point symbols gone.
