What is the safest way to get AI help on a confidential document?
Describe the task abstractly and ask for a template or framework without sharing the real sensitive text
Paste only the first page because partial disclosure is always harmless
Convert the document to PDF first because PDFs are safer than pasted text
Paste the entire document and ask the AI to promise confidentiality
Explanation
The safest pattern is to abstract the problem. Ask for a structure you can apply yourself, rather than sending the actual confidential material.
