PII auto-detect
Click the shield icon. We scan every page for emails, phone numbers, SSNs, credit cards (Luhn-validated), URLs, and IBAN-shaped strings — and place redactions automatically. Review and remove false positives with one click.
True redaction, not just an overlay
Some "redaction" tools just draw a black rectangle on top — the underlying text is still there and can be copied out. FileHook removes the text, then draws the rectangle.
FAQ
Does redaction actually remove the text?+
Yes. The redacted region is rebuilt with the text content removed, then a black rectangle is drawn. Copy-paste returns nothing.
