Privatiser

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)
