Frequently Asked Questions

What counts as prompt injection?
Anything that tries to override your system prompt, extract secrets, or redirect the model. Examples: "Ignore previous instructions", role-reversal attacks ("You are now DAN"), system token injection, encoded payloads.
How reliable is pattern matching?
Catches ~70% of known attacks. Nonvel/obfuscated attacks need ML classifiers. Use this as a first filter — not your only defense. Layer with output filtering, tool-use restrictions, and privilege separation.
False positives?
Yes. Legitimate inputs sometimes contain suspicious patterns ("ignore the formatting"). Review high-risk items manually. Tune thresholds for your use case.

Why Use Prompt Injection Scanner?

You should try Prompt Injection Scanner for a quick, private way to scan user input for jailbreak patterns. All processing happens in your browser. Your files and data never leave your device. According to web.dev, client-side processing is the gold standard for privacy.

On the other hand, dedicated APIs or desktop tools suit batch processing better. They also handle server-side automation. For everyday tasks, browser tools offer the best speed, privacy, and convenience.
