Detection and disclosure.
CAN PEOPLE TELL?
Frequently yes, from characteristic patterns: uniform structure, hedged generalities, absence of specifics, a particular register.
Heavily edited AI output with real substance added is much harder to identify.
DO DETECTION TOOLS WORK?
Unreliably, in both directions.
They flag human writing as AI, and miss AI writing that has been edited.
Do not rely on them for anything consequential.
WHAT GIVES IT AWAY
No specific examples No first-hand experience Balanced to the point of saying nothing Structure that is too even Absence of opinion
SHOULD YOU DISCLOSE?
Depends on context.
For a business's own marketing, generally not expected. For journalism, academic work, or where a client specified original writing, yes. Where a regulation or a professional body requires it, yes.
WHAT MATTERS MORE THAN DETECTION
Whether the content is accurate, useful and adds something.
Content that fails those tests is a problem regardless of authorship.
THE PRACTICAL ADVICE
Add your own substance. That makes the question largely irrelevant.
