Guide - ChatGPT em dashes
Remove ChatGPT em dashes before you paste.
An em dash is not wrong. The problem is repetition: ChatGPT can use long dashes so often that the text starts to look generated.

Short answer
ChatGPT often uses em dashes for asides, transitions, and polished phrasing.
The practical fix is to clean the text before paste, then let the destination app handle simpler content.
Why this paste problem happens
ChatGPT often uses em dashes for asides, transitions, and polished phrasing.
In short workplace writing, repeated em dashes can stand out more than the words themselves.
Replacing every dash blindly is not ideal; sometimes the sentence should be split or rewritten.

The best manual fix is not always find-and-replace. Read each dash in context.
- Search for em dashes and spaced em dashes.
- Replace simple asides with commas or parentheses.
- Split long sentences when the dash is hiding two thoughts.
- Use a simple hyphen only when that fits the sentence.
- Check smart quotes and curly apostrophes while you are cleaning punctuation.
Where the manual fix breaks down
- Blind replacement can make sentences awkward.
- Find/replace does not catch every dash-like character.
- Manual cleanup is repetitive if you use ChatGPT for daily messages.
When you do not need Purifai
- The text is long-form editorial writing where em dashes are appropriate.
- There are only one or two dashes and they read naturally.
- You are already editing the sentence for tone.
When Purifai is worth it
Purifai is worth it when dash cleanup is a recurring final step before pasting AI-assisted work text.
- Normalize long dashes and related punctuation before paste.
- Clean smart quotes, curly apostrophes, and spacing at the same time.
- Prepare text for email, Slack, docs, and Teams without manual find-and-replace.
- Keep the cleanup local on your Mac.
Clean paste is not the same as rewriting
Purifai does not write for you. It only cleans text you already chose.
