## Description

AI PII Scanner is a Firefox sidebar extension that helps prevent accidental privacy leaks by scanning text for personally identifiable information (PII) - entirely locally in your browser.

Before sending prompts to AI tools like ChatGPT, Claude, or Gemini, use this scanner to detect:
• Email addresses.
• Phone numbers.
• Credit card numbers.
• Social Security Numbers (US).
• Street addresses.
• IP addresses.

Key Features:
• 100% offline: no data leaves your device.
• No tracking, no telemetry, no data collection.
• Transparent, deterministic pattern matching.
• Highlighted results with counts, examples, and recommendation.
• Right-click any selected text to scan instantly.
• Copy results for documentation.

Privacy-First Design:
Built for users who value data protection. All processing happens locally using safe, explicit regular expressions - no AI inference, no cloud analysis.

Ideal for:
• Professionals handling sensitive information.
• Privacy-conscious AI users.
• Security and compliance reviewers.

Part of a privacy-focused AI Analysis Toolkit, now expanding to four tools, that promotes responsible AI interaction without compromising personal data.

Note: This tool detects common PII patterns only. It is not a comprehensive privacy solution and should be used alongside good data hygiene practices.
