What to Never Paste Into AI

AI is a chat box that feels private, and that feeling is exactly the trap. You paste in a customer's message to get help with a reply, and without thinking you've just shared their name, their address, and a dollar amount with a system you don't control. Used carelessly, AI becomes a slow leak of the exact information you're supposed to protect. The good news: staying safe takes about five seconds and one habit.

You don't have to choose between using AI and keeping data private. You just have to strip the sensitive bits first.

Share the Problem, Not the Person

The core move is simple: the AI needs the situation, not the identity. It can write a perfect warranty reply without ever knowing the customer's name or where they live. Those details help you — they do nothing for the draft.

Picture an electrician in Sherwood Park drafting a reply to a warranty complaint. Before she pastes it in, she swaps the homeowner's name and the panel's address for [CUSTOMER] and [ADDRESS], keeping only the useful part: "breaker tripping after a subpanel install." The AI writes a spot-on reply, and nothing private ever touched the chat box. She drops the real name back in when she sends it.

That's the whole technique — placeholders. [CUSTOMER], [ADDRESS], [PHONE], [AMOUNT]. Keep the situation intact, mask the identity.

The Hard "Never" List

Some things don't get placeholders — they just never go in at all:

• Passwords, PINs, and account logins. No exceptions, ever.
• Full credit card, bank, or SIN numbers. Not yours, not a customer's.
• Other people's private data in bulk — a whole customer list, a spreadsheet of contacts.
• Anything under a confidentiality or legal agreement you'd have to explain in court.

If leaking it would embarrass you, cost you a customer, or break a law, it stays out of the chat entirely. Placeholders are for context; secrets are for nowhere.

Check Your Settings Once

One more habit worth five minutes: look at your AI tool's privacy settings. Some use what you type to train their systems by default. Most business-grade tools let you turn that off — do it once, and you've closed the biggest quiet risk.

None of this should make you nervous about using AI. It should make you confident. Once masking is automatic — a quick swap before you paste — you stop second-guessing every message and just get the help you need with nothing to regret later.

Private bits masked, situation intact, secrets left out. That's the entire rulebook, and it takes seconds once it's a habit.
