How do I avoid sending customers wrong AI answers?

You have already sent one confidently wrong answer, and it stung. Let that sting teach you rather than shame you. The trouble is that the AI sounds just as sure when it is wrong as when it is right, and that confidence is exactly what fooled you. Its tone is not evidence. A reply can be polished, friendly, and completely mistaken about your product or this customer's actual situation. Your job is not to pass along what sounds good but to send what is true. That means the suggestion is a starting point you verify, never an answer you forward on trust. When the stakes are real, check it against what you actually know. Make one habit: before you send anything the tool wrote, ask whether you know this is true or it just sounds true. If you are not sure, look it up or ask someone. Those extra thirty seconds are the difference between help and harm, and the customer can always tell which one they got.
