PII & Secret Redactor for Prompts

Scan text for emails, API keys, tokens, and other sensitive data before pasting it into ChatGPT, Claude, or any LLM — everything runs in your browser, nothing is uploaded.

Detection is pattern-based (regex + Luhn check for card numbers) and will miss context-dependent secrets or produce occasional false positives — treat this as a second pair of eyes, not a guarantee. Nothing you type here is sent anywhere; it never leaves your browser.

About the PII & Secret Redactor

Copy-pasting logs, support tickets, or debug output into a chat LLM is one of the easiest ways sensitive data ends up somewhere it shouldn't. This tool scans text for common patterns — emails, phone numbers, IP addresses, credit card numbers (Luhn-validated), and API keys/tokens from OpenAI, AWS, GitHub, and Slack — and produces a redacted version you can safely paste instead.

Key Features

  • Detects emails, phone numbers, IPs, SSNs, credit cards, JWTs, and common API key formats.
  • Toggle detection categories on or off and see exactly what was matched before redacting.
  • 100% client-side — the text you paste here is never sent to a server.
