Real-time detection and prevention of prompt injection attacks. Secure your AI systems with pattern matching, heuristic analysis, and input sanitization.
Test the detector with your own inputs
Multiple layers of defense against prompt injection attacks
25+ regex patterns detecting instruction overrides, jailbreaks, role manipulation, and more.
7 behavioral heuristics analyzing entropy, structure, repetition, and instruction density.
Combined scoring system with configurable thresholds for blocking and warning.
Clean control characters, escape delimiters, normalize whitespace, and handle homoglyphs.
Process inputs in milliseconds. Batch processing support for high-throughput applications.
Add custom patterns, configure thresholds, and integrate callbacks for your use case.
Protection against six major categories of prompt injection attacks
Attempts to override or ignore system instructions
Attempts to change the AI's role or persona
Breaking out of the current context or prompt
Attempts to extract sensitive information
Bypass safety measures entirely
Using encoding to hide malicious content
Get started in minutes with simple, intuitive API
