Prompt Injection Tester
Test your AI system prompts against 50+ injection attacks — jailbreaks, role-play escapes, encoding tricks. Get a vulnerability score and hardened version.
What is Prompt Injection and Why Should You Test for It?
Prompt injection is the #1 security vulnerability in AI applications. It occurs when an attacker crafts input that tricks your AI into ignoring its system prompt and following malicious instructions instead. This can lead to data leaks, unauthorized actions, and reputation damage.
As AI systems handle more sensitive tasks — customer support, code generation, document analysis — securing your system prompts is no longer optional. The OWASP Top 10 for LLM Applications lists prompt injection as the most critical vulnerability.
Our tester runs your system prompt against 26 real-world attack patterns across 9 categories: jailbreaks, role-play escapes, encoding tricks, prompt leaking, context manipulation, social engineering, payload smuggling, multi-turn attacks, and output manipulation. Each test analyzes your defenses and provides specific remediation advice.
Everything runs in your browser. Your system prompt never leaves your device. After testing, you get a hardened version with security guardrails automatically added for every vulnerability found.
