Keep private information out of your prompts

Works with ChatGPT · Claude · Copilot

What you’ll be able to do

You can learn what not to paste and how to get help without sharing sensitive data.

The problem

It is easy to paste private details you should not share with a tool.

What this skill does

Ask AI to help using stand-ins instead of real names and numbers.

When to use it

  • Any time your task involves personal, financial, or confidential details.
