Highcloak 作成者: Blueinit LLC

Highcloak catches personal data in your AI prompts before they leave your machine.

Paste a customer's Social Security number into ChatGPT? Highcloak blocks it. Type a credit card number into Claude? Blocked. Phone number in Gemini? You'll see a warning.

WHAT IT DETECTS

Social Security numbers
Credit card numbers (with Luhn validation)
Email addresses

Dates of birth

Driver's license numbers
HOW IT WORKS

You type into ChatGPT, Claude, Gemini, or Copilot
Highcloak scans your text locally in the browser
If PII is found, you see a warning or the send button is blocked
Choose to redact the data or remove it yourself
YOUR DATA NEVER LEAVES YOUR MACHINE All detection runs locally using pattern matching in the browser. Highcloak does not send your text anywhere. No cloud processing. No server required. No account needed.

Don't trust us — verify. The detection engine is open source.
