🛡️ Prompt PII Scrubber
🔒 Secure & Client-side
Mask sensitive data (emails, phones, SSNs, credit cards, API keys, IPs, URLs) before pasting prompts into ChatGPT, Claude, or any AI service. Runs entirely in your browser — your text never leaves the page.
Masked items:
How to use
- Paste the prompt or document you want to send to an AI service.
- Toggle the categories you want to mask (default: all on).
- Click Scrub; the right panel shows the masked version with placeholders like
[EMAIL],[PHONE], etc. - Copy the scrubbed text and paste it into ChatGPT, Claude, Gemini, etc.
What is detected: standard email addresses; phone numbers in common international formats; US SSN and Korean RRN (주민등록번호); credit-card-like number sequences validated with the Luhn algorithm to avoid false positives; API keys matching well-known prefixes (sk-, pk-, AKIA, AIza, github_pat_, xoxb-); IPv4 addresses; and any HTTP(S) URL.
Heuristic limits: free-text addresses, names, and proprietary IDs are not detected. Always review the scrubbed output before sending.
