How to let ChatGPT buy things safely

Why shouldn't I just give ChatGPT my card number?

Typing your card number into a chat means it could end up in your conversation history, be shared by mistake, or be used for a purchase you didn't expect. There's no built-in limit on what that number can be charged, so a single misunderstanding could become an expensive one.

AI assistants are helpful, but they can misread what you want. They may pick a pricier option, add an extra item, or follow instructions hidden on a shopping page. None of that is a problem if the card they're using physically can't go over a limit you chose.

That's the idea behind an allowance: you decide the boundaries once, and the card network enforces them every time.

How do I connect ChatGPT to AI Allowance?

Create a free AI Allowance account, verify your identity once, and save your Visa or Mastercard in the secure card form. Then add AI Allowance as an app in ChatGPT's settings using the connection link we give you. It takes a few minutes and needs no technical knowledge.

• Sign up at AI Allowance and verify it's you.
• Save your card — we only keep a label like “Visa ending 4242”.
• In ChatGPT, open Settings → Apps and add AI Allowance with your connection link.
• Ask ChatGPT to use AI Allowance when it's time to pay.

What limit should I set for ChatGPT?

Start small and specific. A good first allowance covers one job — say $75 a week for groceries — rather than “anything up to $500”. You can always raise it later. Pick an end date too, so the allowance doesn't keep running after you've stopped needing it.

You can choose how often the limit resets: one time (great for a single trip or gift), every week, or every month. You can also restrict it to store types such as groceries, books or travel, or to one single store.

Before you confirm, AI Allowance shows a sentence like: “Shopping helper can spend up to $75 a week on groceries until Dec 31.” If that sentence matches what you want, you're set.

What happens when ChatGPT tries to pay?

ChatGPT asks AI Allowance for a card number. If the purchase fits your allowance, it gets a one-time card number valid for that payment only. If it's over the limit or at a store you didn't allow, the request is declined. Either way, you get an alert.

The one-time card number isn't your real card number, and it stops working after it's used. So even if it were copied, it couldn't be used again.

How do I stay in control day to day?

Turn on alerts so you hear about every purchase, or just the declines and approvals. Add an “ask me first” amount so bigger purchases wait for your OK. And remember the off switch: one tap pauses ChatGPT, and “Pause all AIs” stops everything at once.

• Every purchase appears in your activity feed with the store, amount and status.
• Purchases over your “ask me first” amount show Approve and Decline buttons.
• If something looks wrong, pause first and ask questions later.

What if ChatGPT buys the wrong thing?

Contact the store first, as with any online order. Because the purchase was made on your own Visa or Mastercard, your card issuer's normal dispute protections still apply. Then tighten the allowance — fewer store types, a lower limit, or a lower “ask me first” amount.
