See what's in your prompt before you send it
Paste text the way you'd send it to an AI tool, and see which parts look like personal data — before it leaves your machine.

Runs entirely in your browser. Nothing you type here is sent to MaskFlare or anywhere else.
What would be redacted
Redacted output will appear here as you type.
This demo matches emails, phone numbers, IP addresses, card numbers (Luhn-validated), IBANs, and US-format SSNs using pattern matching — it's illustrative, not the full MaskFlare detection engine, and it will miss names, addresses, and organization-specific identifiers a production policy would also cover.
Want this running automatically, before a prompt ever leaves your organization? Read how MaskFlare approaches PII redaction.
