The line I never let cross into cloud tools

Every business has a few kinds of information that should never land in a general cloud AI tool: full client contracts, bank details, medical notes, passwords, anything with someone else's private information attached. Once you paste that kind of text into a tool you do not control, you cannot fully take it back.

I keep a short mental list of what falls into that category, and I treat it the same way every time, no exceptions for a quick question or a busy afternoon. The rule only works if it is automatic, not something I have to think through each time I open a chat window.

A local model changes the math here. Because the text never leaves your machine, the same sensitive information becomes fair game for a tool that lives on your own computer instead of a stranger's server.

Try this today: write down the three kinds of information in your business that should never go into a general cloud AI tool, and keep that list somewhere you will actually see it.
