What can I safely paste into AI?

Describe what the information is, don’t paste the actual sensitive content:

I'm about to paste something into an AI tool. Here's what it is,
described rather than shown: [DESCRIBE THE INFORMATION, NOT THE
INFORMATION ITSELF, e.g. "a customer's full billing address and
order history"]

Is this generally safe to paste (green), something to pause and
check against my company's policy first (yellow), or something
that should never be pasted, only described structurally (red)?
Give a one-line reason and a safer alternative if it's yellow or red.
