Detect & Redact
🔍 What Was Redacted
No PII Detected
This text appears safe to share with AI. No personal data was found.
How It Works
Step 1: Regex Scan
Instantly detects emails, phones, credit cards, API keys, IPs, and IDs using pattern matching.
Step 2: AI Detection
Claude AI finds names, addresses, and company names that patterns can't reliably catch.
Step 3: Safe Text
All PII replaced with clear placeholders like [NAME], [EMAIL], [PHONE]. Ready to share.
Frequently Asked Questions
Is my text sent to a server? ▼
Regex detection runs 100% in your browser — no data sent anywhere. The optional AI detection (for names and addresses) sends text to our secure API which uses Claude. You can disable AI detection with the toggle if you prefer fully local processing.
What replacement placeholders are used? ▼
Each PII type gets a clear, readable placeholder: [NAME], [EMAIL], [PHONE], [ADDRESS], [COMPANY], [CREDIT_CARD], [API_KEY], [SSN], [IP_ADDRESS], [BANK_ACCOUNT]. This lets the AI understand the context without seeing the real data.
How accurate is the detection? ▼
Regex patterns are ~95%+ accurate for structured data (emails, phones, cards). AI detection is ~90% accurate for names and addresses. Always review the sanitized text before sharing sensitive documents.
Does this work with Norwegian personal data (NIN)? ▼
Yes! Norwegian National Identity Numbers (11-digit fødselsnummer) are detected and redacted, along with international formats. Norwegian phone numbers (+47 format) are also fully supported.
