Guides to using AI without sharing private details
Plain answers on masking, redaction, and AI privacy. Each guide shows when it was last reviewed.
Before you share with AI
Questions to settle before a document goes into an assistant.
- Can accountants share spreadsheets with ChatGPT or Claude?
Before sharing client spreadsheets with ChatGPT or Claude, check authorization, confidential details, and what the task actually needs.
- Data masking vs. data redaction: which should you use?
Compare data masking, permanent redaction, and de-identification. Learn when a reversible working copy or a final redacted document fits your task.
- PHI vs PII: what is the difference?
Learn how PHI differs from PII, why document context matters, and which names, dates, and details need closer attention in a patient record.
- Can therapists use ChatGPT for session notes?
Yes, once the identifying details are out of the note. Your ethics code already covers this, and a business associate agreement reaches only some account types.
- Can you put patient information into ChatGPT?
Only on an account covered by a signed business associate agreement, which rules out consumer plans. No regulator certifies products, so check the contract.
- Can lawyers paste client documents into ChatGPT?
The confidentiality duty covers a client's business and affairs, not just privilege. Law societies have said it reaches these tools. Sort the task first.
- What metadata is stored in a photo or PDF?
A photo can carry the camera, the time, and the coordinates where it was taken. A PDF carries an author name. What is in there, and how to remove it.
- How to detect prompt injection in a document
Review visible instructions, disguised text, and concealed content in documents, with examples and clear detection limits.
Compare tools
What each kind of tool asks of you, and where it fits.
- PHI Mask vs. free redaction tools
Every free redactor makes you find the identifiers yourself. What Adobe, Preview, PDF24, Stirling, and LibreOffice document, and where detection changes it.
- PHI Mask vs. browser privacy extensions
Prompt-scrubbing extensions act on the chat box; document masking acts on the file. Where each one's coverage ends, and why running both is reasonable.
- PHI Mask vs. redaction software
A model, a cloud API, an SDK, and a subscription all redact. What each asks you to stand up first, and which of them read a screenshot.
