100% Client-Side Privacy
All detection and text replacement execute strictly inside your browser memory. No data is ever transmitted over the network.
Luhn Algorithm Card Validation
Validates 13-19 digit card numbers using the standard Luhn checksum algorithm to prevent false positives on general numbers.
Flexible Redaction Formats
Switch between uniform [REDACTED] blocks and contextual tokens like [EMAIL_1] or [API_KEY_1] to preserve text structure.
Custom Regex Pattern Support
Add your own custom regular expressions to automatically mask proprietary IDs, ticket numbers, or internal account codes.
Granular Match Review
Inspect every single match individually with line context before applying redactions to ensure accurate results.
