How this works

This scanner runs the exact public regex patterns from the LeakSnitch engine, right in your browser tab. It shows what a chatbot would receive if you submitted the text above. The real LeakSnitch extension adds context signals, entropy analysis, and checksum validation on top, so blocking decisions are even more precise than this quick check.

  • 100% client side, nothing is uploaded
  • 55+ public patterns covering keys, tokens, passwords, and PII
  • Severity mirrors the production scoring engine
  • Instantly see leaks before an AI ever would

Stop these leaks automatically

The scanner checks manually. The LeakSnitch extension blocks in real time, under 50ms, on every AI platform your team uses.
