How the privacy checker works
The checker uses local regular-expression patterns to find common things people accidentally paste into AI tools: emails, phone-like strings, SSN-like IDs, credit-card-like numbers, API keys, bearer tokens, private key headers, and common secret variable names.
It is intentionally conservative. A false positive is cheaper than accidentally sending a real credential, customer email, or internal token to a third-party AI system.
Limitations
Pattern matching cannot understand every secret. It may miss names, addresses, internal project codes, unusual credentials, screenshots, proprietary text, or regulated data that does not match a simple pattern. Treat the output as a checklist, not approval.

Frequently asked questions
Does this guarantee my text is safe to paste into AI?
No. This is a pattern-based reminder tool. It can miss sensitive information and can flag harmless text. Review the text yourself before sharing it.
Is the text uploaded for scanning?
No. The checks run in your browser with JavaScript. Your text is not sent to a server.
What should I do when something is flagged?
Remove, redact, or replace the sensitive value before sending the text to an AI tool. For example, replace real emails with person@example.com and real keys with [API_KEY_REDACTED].
