What Is a Prompt Injection Checker?

The Prompt Injection Checker scans a prompt for common injection and jailbreak patterns, such as attempts to override instructions, reveal the system prompt, escalate privileges, or request secrets. It labels findings as high-risk or caution to help you review untrusted input.

How to Use This Prompt Injection Checker

1
Paste the promptEnter a prompt or a user-supplied message.
2
Read the findingsReview each detected pattern and its risk level.
3

Frequently Asked Questions

No. This is a heuristic scan that catches common known patterns. Robust defenses combine input validation, output filtering, least-privilege tool access, and monitoring.

Instruction overrides, system prompt extraction, role-delimiter injection, privilege escalation, secret disclosure requests, persona takeover, and known jailbreak phrasing.

Yes. Legitimate text can match a pattern (for example, a support article about 'ignore previous instructions'). Use the findings as a review aid, not a final verdict.
