Before It Reaches AI
Preview local regex masking for common identifiers before sharing text with AI tools. This browser demo is not the full Masker API.
Paste text to preview regex masking for emails, phone numbers, and card-like numbers. Review the result before use.
Pasted text is processed by this page's client-side JavaScript and is not sent to the Masker API.
The preview highlights email addresses, phone numbers, and card-like 16-digit strings.
Use the documentation to run the Python API locally and review its supported entities and deployment boundaries.
