Auto-Redact PII
Local PII detection finds email addresses, phone numbers, credit-card numbers (Luhn-validated), Indian PAN numbers, Aadhaar-style IDs (Verhoeff-validated), IP addresses and custom regexes. Every finding is a suggestion: review, deselect, then redact permanently with verification.

Frequently asked questions
▸Does detection send my text anywhere?
No. All scanning happens in this browser tab using local pattern matching and checksum validators.
▸Can it miss things?
Yes - detection covers common patterns only. Review carefully; run OCR PDF on scanned pages first because image-only pages have no text layer to inspect.
