About this extension
Privatiser automatically anonymizes sensitive content when you paste into AI chat sites like ChatGPT, Claude, Gemini, and Copilot.
HOW IT WORKS:
• Paste into any supported AI chat — sensitive data is automatically replaced with consistent pseudonyms
• The AI can still understand and help with your text because the structure is preserved
• Copy the AI's response — original values are automatically restored to your clipboard
WHAT IT DETECTS:
• Secrets: API keys (AWS, OpenAI, GitHub, Slack), JWTs, bearer tokens, PEM keys, connection strings, SSH keys
• Network: IPv4 addresses, domain names, email addresses, MAC addresses, internal URLs
• PII: Phone numbers (US/UK), credit cards (Luhn-validated), Social Security numbers, passport numbers, IBANs
• Cloud: AWS account IDs, ARNs, S3 buckets, Azure subscription IDs, GCP project IDs
• Identifiers: UUIDs
FEATURES:
• Auto-anonymize on paste into AI chat sites
• Auto-restore originals when copying AI responses
• Right-click context menu for manual anonymize/deanonymize
• Toggle pattern categories on/off (Secrets, Network, PII, AWS, Cloud, Identifiers)
• Allowlist specific values to skip
• Built-in anonymize/deanonymize tool in the popup
• Mapping table to see what was replaced
PRIVACY:
• 100% local processing — no data is sent anywhere
• No analytics, no telemetry, no external requests
• Mappings stay in your browser session only
SUPPORTED SITES:
• ChatGPT (chat.openai.com, chatgpt.com)
• Claude (claude.ai)
• Gemini (gemini.google.com)
• Copilot (copilot.microsoft.com)
