Presidio JS — Client-Side PII Scanner

About Presidio JS — Client-Side PII Scanner

PresidioJS detects and anonymizes PII entirely in your browser. No servers, no API keys, no data ever leaves your machine. Supports regex-based detection (emails, phones, IBANs, credit cards, SSNs, crypto wallets, insurance numbers) plus browser-native NER for names, organizations, and locations using a local ML model. Built for privacy-first workflows like sanctions screening and compliance. One HTML file, zero dependencies, works offline. Open source and free.
