Why em dashes became a problem
The em dash is perfectly good punctuation, but AI chat models use it far more often than most human writers do. Several em dashes per paragraph has become one of the most recognizable signs of machine-written text, so editors, teachers, and readers now notice them instantly. If you use AI for drafting, swapping the dashes out is the fastest way to make the text read like your own voice.
Choosing a replacement
- Comma. The most natural choice for ordinary prose. An em dash usually marks a pause that a comma handles just as well.
- Hyphen. Keeps a visible dash, just the plain ASCII one. Useful for plain-text environments like code comments or commit messages.
- Space. Simply opens the sentence up. Works when the dash was decorative rather than structural.
- Delete. Removes the dash and closes the gap. Best for lists and headings where no pause is needed.
The tool also handles en dashes and horizontal bars, trims doubled spaces left behind, and fixes spacing before punctuation. For a deeper clean that also straightens quotes and strips Markdown, use the AI Text Cleaner listed below.
Frequently asked questions
What is the difference between an em dash, en dash, and hyphen?
A hyphen (-) joins words, an en dash spans ranges like 2020 to 2024, and an em dash is the long dash used as a pause in a sentence. This tool replaces em dashes, en dashes, and horizontal bars, and leaves ordinary hyphens alone.
Why does ChatGPT use so many em dashes?
The writing the model learned from uses em dashes as a flexible connector, and the model leans on that habit heavily. The density of em dashes in AI output is much higher than in typical human writing, which is why it reads as a tell.
Will replacing dashes with commas always be grammatical?
Almost always, because an em dash usually marks the same pause a comma does. Skim the result for the rare sentence where a period would read better.
Does the tool change anything besides dashes?
It only replaces the dash characters and tidies the spacing around them. Words, quotes, and formatting are untouched.
Is my text uploaded?
No. The replacement happens in your browser and the text never leaves your device.
