Is it safe to upload PDFs to ChatGPT, Claude, or Gemini?
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.
