  Aegis Personal — Use AI safely.

  Protect your personal data while using AI chatbots.
  
  Aegis Personal is a privacy-first browser extension that guards your sensitive information when interacting with AI services.
  
  It uses a machine learning model (NER) to intelligently detect personal information in your prompts and automatically masks it before sending — then restores it in AI responses so your workflow stays seamless.
  
  🔒 Smart PII Detection (ML-Powered) • Uses a trained Named Entity Recognition (NER) model to detect personal information with high accuracy (F1: 0.98+) • Goes far beyond simple pattern matching — understands context to catch PII that regex-based tools miss • Detects 18 categories of sensitive data including:
  
  Names (given name, surname)
  Contact info (email, phone number)
  ID numbers (SSN, passport, national ID, driver's license, Korean RRN)
  Financial data (credit card, bank account number)
  Location (street address, city, zip code)
  Digital identity (username, password, IP address)
  Other (date of birth, company name)
  🔄 Automatic PII Proxy • Detected personal data is replaced with realistic fake values before being sent to AI • AI responses containing pseudonymized data are automatically restored with your original information • Your real data never reaches AI servers
  
  ⚡ Silent & Seamless • Works quietly in the background — no interruptions for safe conversations • Shield badge indicates real-time protection status • Alerts only appear when PII is detected • Weekly protection reports show your safety stats
  
  🌐 Wide Compatibility Works with 30+ major AI chatbot services. See our homepage for the full list of supported sites.
  
  🏢 Enterprise Ready • Connect to AEGIS Server for organization-wide policy enforcement and advanced threat protection • API key-based activation for enterprise features
  
  🔐 Privacy First • All PII detection and masking runs locally in your browser • ML model inference via WebAssembly — no cloud API calls for analysis • No account required for personal use • No tracking or analytics • Open source (AGPL-3.0)
  
  Aegis Personal — Use AI without exposing your identity.
