Tips › How to prompt better

What should you not paste into an AI tool?

What you paste into an AI tool is sent to the service that runs it. Before you paste, it is worth thinking about what is in the text.

Personal data

Names, addresses, health details and student or customer records belong to someone. Remove or replace them unless you are sure the service and your rules allow it.

Secrets and credentials

Passwords, access keys and private documents should not go into a prompt. Use placeholders for anything of that kind.

Unpublished material

Drafts, contracts and internal plans may be covered by confidentiality. Check your organisation's rules first.

How to do it safely

Replace sensitive parts with plain placeholders such as [NAME] or [AMOUNT], and fill them in again after you have the result. If a text cannot be made anonymous, it may be better not to use the tool for it.
