Which one exactly? Can you be more specific. Depending on chatbots/ai detection tools isn't that reliable. I have used many AI detection tools in the past, none of them are that good. They were never accurate and gave false positive results. So accusing someone based on those is not something I would prefer. In many cases, I have seen one tool would detect a content as AI and another tool detect the same content as human made. What would you make of that then!. Instead, I rely on my instinct, you can tell whether its AI or not. Not always, but your guts can tell something is wrong/fishy. That's the most powerfully tool.
