Em Dashes and AI Writing: Style Choice, Not Proof
An em dash is normal punctuation. Frequency can be a style signal, but a single character cannot identify who wrote a passage.
Em dashes have been used by human writers for centuries. They create interruption, emphasis or an aside. Modern language models also use them because they are common in edited prose.
Why people associate them with AI
Generated drafts may use a polished explanatory style and repeat the same punctuation pattern. Readers notice the repetition, then treat the character itself as evidence. The real issue is usually rhythm and variety, not the existence of an em dash.
When conversion is appropriate
Use a hyphen or rewrite the sentence when a publishing style guide forbids em dashes, a legacy system requires ASCII, or the paragraph genuinely overuses interruptions. Keep the character when it improves clarity.
