Anonymize personal data before it reaches your AI chat assistant. Encrypt PII, auto-decrypt responses. Privacy by design. cloak.business — Anonymize personal data before it ever reaches an AI chat. cloak.business automatically detects and anonymizes personal and sensitive information in your prompts before they are sent to an AI chat assistant. Sensitive values are encrypted on the way out and seamlessly decrypted inside the AI's response — so you keep full, readable answers while your real data stays under your control. HOW IT WORKS 1. Type your prompt as usual. 2. cloak.business intercepts it and detects PII — names, emails, phone numbers, addresses, IDs, secrets and more. 3. A preview shows exactly what was found and how it will be protected. You stay in control. 4. The anonymized prompt is sent to the AI. 5. The response is automatically decrypted in place, so you read the original values — highlighted, with a one-click toggle between original and protected view. KEY FEATURES • Detects 317 entity types — names, emails, phone numbers, postal addresses, national IDs, payment data, API keys and infrastructure secrets • 5 anonymization methods: Encrypt (reversible), Replace, Mask, Redact and Hash • Country presets so you protect data according to the rules that matter to you • Reversible encryption with AES-256-GCM using your own encryption keys • Automatic in-response decryption with visual highlighting and detail tooltips • Preview modal — review and adjust every detection before anything is sent • Anonymize the text of common document and data files • Fully localized in 48 languages SUPPORTED AI ASSISTANTS Works directly inside leading AI chat assistants such as ChatGPT, Claude and Gemini — and other AI chat platforms you choose to enable.
