## Overview

AI assistants are powerful document readers — and they process uploads under the AI vendor’s terms. That can be acceptable for non-sensitive drafts and unacceptable for payroll, IDs, or client secrets. Local sanitize does not replace enterprise AI controls; it reduces accidental oversharing.

## Verdict

Do not upload confidential PDFs to consumer AI chats. Sanitize and paste minimal text, or use your organisation’s approved AI workspace.
