What should a complete beginner avoid typing into an AI chatbot?
Information to keep out
Passwords, verification codes, and full account numbers should never go into a chat. Government ID numbers, Social Security numbers, and passport details also belong somewhere else. Even partial details can help someone piece together who you are.
Health information and private family matters deserve caution too. A chatbot can still help with general questions if you describe the situation without names or exact records.
Work and client material
Company documents, unreleased plans, customer lists, and source code can violate workplace policies when shared with outside tools. Check your employer's guidance before pasting anything, and remove names and identifying details first.
Summaries of general topics are usually safer than full files. You can describe the problem in general terms and still get useful help. Treat privacy settings and sensitive data as the first lesson, before you learn any advanced prompt tricks or features, since they matter more.
Habits that help beginners
Read the app's privacy notice once, even if it is long. Use a separate account for experiments, and delete chats that contain anything sensitive. Good habits take a few minutes and prevent most avoidable problems. Once these habits feel normal, they take almost no extra effort at all.
Common mistakes
- Pasting a full customer list into a chatbot to save time on a spreadsheet task.
- Assuming a chat window is as private as a text message to a trusted friend.
