The em dash is the most recognizable sign of AI-written text. CleanyAI finds every em dash and double dash in your copy and swaps it for natural punctuation, a comma, a period, or a clean hyphen, so your writing reads like a person wrote it.

  • Em dashes (the long dash) replaced with a comma, period, or hyphen by context

Em dash questions

Why is the em dash considered an AI tell?
Large language models lean heavily on the em dash because it is grammatically flexible. People type it far less often, partly because it is awkward to enter on most keyboards, so a string of em dashes is a common signal that text was AI-generated.
What does the em dash get replaced with?
CleanyAI picks natural punctuation based on context, usually a comma or a period, and falls back to a plain hyphen where a connector reads better. The goal is text that no longer looks machine-formatted.
Will it also remove other formatting?
Yes. In the same pass it can strip Markdown, headings, bold, and lists, so you get fully clean plain text, not just dash fixes.
