Secure Your AI Use · Lesson 1Free~12 min readEssential for everyoneYour never-paste list by the end

Use AI without getting burned.

AI is a force multiplier and a data leak waiting to happen if you’re careless. This lesson is the safety basics everyone should have: what you must never paste, where your data actually goes, the quiet risk of “shadow AI,” and a few simple rules that keep you protected without slowing you down.

The mental model

AI is powerful but leaky. Safety comes down to two questions: what am I sharing, and where does it go?

Every time you paste something into an AI, you’re sending it to someone else’s computer. Often that’s fine. Sometimes it’s a serious problem. The whole of personal AI safety is learning to tell the difference before you hit enter — because once something’s sent, you can’t pull it back.

The Reframe

Treat the prompt box like a public postcard. Before pasting, ask: would I be comfortable if this ended up somewhere I didn’t control? If not, don’t paste it as-is.

Step 01 What never to paste

Keep these out of any AI tool unless you’ve confirmed it’s approved and protected for that use:

Step 02 Know where your data goes

Not all AI tools treat your data the same. Before trusting one with anything sensitive, check:

The “is it private?” check

  1. Does it train on your inputs? Many consumer tiers may; many business/enterprise tiers don’t.
  2. Consumer vs business tier. Business and enterprise plans usually add data protections and admin controls.
  3. Is there a clear policy? If you can’t tell what happens to your data, treat it as not private.

Step 03 The shadow-AI risk

“Shadow AI” is employees quietly using random AI tools with company data — no approval, no protections. It’s usually well-intentioned and genuinely risky: confidential data flowing into tools nobody vetted. Naming it is the first step to fixing it.

Step 04 Simple personal rules

The convenience trap gets careful people: pasting a whole customer email or a full contract for a “quick summary” leaks every detail inside it. The fix is usually easy — remove the sensitive parts, or use an approved tool — but you have to catch yourself before you paste, because there’s no undo.

Your challenge: audit your own habits

Take an honest look at how you use AI. Then:

  1. List the AI tools you currently paste work into.
  2. For each, check whether it trains on inputs and what tier you’re on.
  3. Write your personal “never paste” list of data types.
  4. Pick one safer habit to adopt this week (anonymizing, an approved tool).

That’s the difference between using AI and getting burned by it. Next, turn personal safety into a business AI policy your whole team can follow — that’s Lesson 2.

What you can do now

  • Ask “what am I sharing and where does it go” before pasting
  • Recognize the data types you must never paste
  • Check whether a tool trains on inputs and is private
  • Understand and name the shadow-AI risk
  • Adopt simple personal rules that keep your data safe
