================================================================

"Paste into AI safely. Your secrets never leave your device."

One click. Zero exposure. Get the full power of AI without
risking your most sensitive data.

■ Why You Need PII Scrubber
----------------------------------------------------------------

Every day, engineers, IT teams, and business professionals paste
sensitive context into ChatGPT — log files with IP addresses,
colleague emails, API keys from config files, customer data from
spreadsheets.

One careless paste is all it takes to leak credentials that
cannot be unshared.

PII Scrubber automatically detects and masks sensitive data
before it ever reaches an AI model — entirely inside your
browser, with zero server contact.

  Click "Copy Masked" next to the ChatGPT send button. Your

  Paste and send with complete confidence.

  internal IDs — and they are replaced with [custom]
  automatically on every use.

Smart Precision
  Credit cards validated by the Luhn algorithm to eliminate
  false positives. Handles text directly attached to PII
