Automatically detect and mask 25+ types of PII before sending to AI apps. 100% local, never stores your data.
Email, phone, SSN, credit card, passwords, API keys, IPs, crypto wallets, MAC, DOB, passport, license, address, bank, and international formats (UK, India, China, Australia, Canada).
Credit cards are verified using the Luhn algorithm. Invalid check digits are flagged with reduced confidence, cutting false positives.
Switch between placeholder mode [TYPE_N] and realistic fake data mode. Fake data preserves format so AI responses still make sense.
PII is highlighted with colored underlines as you type. Each PII type has a distinct color so you can see exactly what will be masked.
Aggregate 0-100 risk score based on PII sensitivity. Export results as JSON or CSV for auditing and compliance.
All processing in your browser. Installable as a Progressive Web App for offline use. No data ever leaves your machine.
Start a local REST API with cli.js serve — POST /scrub, POST /scan, GET /rules, GET /health. Integrate PII detection into any pipeline.
