AI Privacy and What Not to Paste

You're mid-task. You have a messy email thread, a spreadsheet, a contract draft, maybe a customer's complaint with their name and account number in it. The chatbot is right there, and it would clean all of this up in ten seconds. Your finger hovers over paste.

Stop for a moment. That paste is the whole privacy question in one gesture. Whatever you put in that box leaves your machine, travels to a company's servers, gets processed, and may be stored for a while - sometimes a long while. Most of the time nothing bad happens. But "most of the time" is not a plan, and the times it goes wrong tend to involve exactly the data you'd least want loose: a password, a customer's medical detail, an unannounced acquisition, the API key that runs your production system.

This guide is for normal people doing real work - founders, ops folks, writers, support agents, anyone who reaches for AI to get through the day. You don't need to understand how these models are built. You need three things, and that's the arc of the four phases here. First, a clear picture of where your words actually go after you hit send: who keeps them, for how long, and the real gap between a free consumer account and a paid business one. Second, a concrete list of what should never go into a general chatbot - secrets, credentials, customer personal data, regulated information, and your company's unreleased plans - with examples so you can recognize them in the wild. Third, the habits that let you keep using AI for almost everything anyway: redacting before you paste, sticking to tools your organization has actually approved, knowing when a model running on your own machine is the right call, and finding out what your own AI policy says before someone in legal finds out for you.

None of this is about fear, and none of it means you should stop using these tools. It's about drawing one line in the right place so you can move fast everywhere else without lying awake about it.
