Frequently asked questions
Why replace em dashes?
Em dashes (—) are a strong tell that a piece of text was written or heavily edited by an AI model like ChatGPT or Claude. Swapping them for hyphens or commas makes the writing read more like a person.
What is the difference between -, –, and —?
'-' is a plain hyphen (used in compound words). '–' is an en dash (used for ranges like 2020-2024). '—' is an em dash (used for interruptions or asides). This tool targets em dashes by default and can optionally also replace en dashes.
Does this tool run any AI?
No. It's a simple find-and-replace running entirely in your browser - no API calls, no model, no cost, no data leaving your device.
Will it change any other punctuation?
No. Only em dashes (and optionally en dashes) are touched. Every other character in your text is preserved exactly.
Is my text uploaded anywhere?
Never. All replacement happens locally in your browser. Nothing is stored, logged, or sent to a server - safe for private drafts, client work, or anything sensitive.
Can I remove em dashes without leaving a hyphen?
Yes. Pick 'Remove entirely' and the em dash is deleted with adjacent double spaces collapsed. Use a comma or 'space - hyphen - space' if you want a more natural sentence break instead.
