Why Mazkits?
Everything you need, nothing you don't.
Smart PII detection
Built-in rules for email, phone, ID cards, bank cards, IP addresses, and more — with China, Global, and Developer presets.
Preview before you export
See highlighted entities in the first 20 lines, review the pending redaction list, and dry-run replacements before writing any file.
Flexible redaction strategies
Mask sensitive data, hash it irreversibly, replace with fake data, or tokenize with a local vault for reversible redaction.
AI workflow ready
