The one-character edit that de-AIs your text
The em dash became the most talked-about punctuation mark of the AI era. ChatGPT, Claude, and Gemini all use it heavily — often several times in a single paragraph — and readers noticed. Whatever you think about that, if you publish AI-assisted drafts, dash density is now the first thing to fix.
Paste your text, pick a replacement, and every em dash is swapped in a way that keeps the sentence readable: spacing is normalized around the replacement, and if you choose period, the following word is capitalized automatically.
Fixing more than dashes?
Em dashes rarely travel alone. If the text came from an AI assistant, run it through the AI Text Cleaner instead — it handles em dashes with the same options, plus curly quotes, hidden characters, and a highlighter for stock AI phrases.
