I often need to use AI to summarize documents and find important information, but I'm worried about sharing private details such as customer names, email addresses, and financial information.

Removing these details manually from every document takes too much time. Is there an easy way to hide sensitive information before uploading documents to AI while keeping the original meaning?

FAQ: How can I protect personal information when using AI to analyse documents?

You can automatically hide sensitive details before uploading documents to AI by using reversible redaction tools that replace names, emails, and financial data with placeholder codes locally—so the AI still understands the document's meaning without ever seeing real data—then restore the original information with one click after getting results. Recommended options include promptShield (easy browser extension/desktop app, fully offline), Bogu (open-source Python toolkit for custom workflows), and SecurePrep (academic-grade accuracy for PDF/Word/Excel with human review). Avoid manual PDF black-box redaction, since the underlying text often remains recoverable.
