Paste any text and instantly see:
- Risk Score (0–10) with color-coded severity
- Detected Threats with category, pattern name, and matched context
- 9 Example Attacks from Easy to Hard across all attack categories
| Category | Patterns | Examples |
|---|---|---|
| Prompt Injection | 8 | Direct overrides, role play escapes, delimiter injection, context overflow |
| Dangerous Commands | 4 | Shell exploits, reverse shells, privilege escalation |
| Code Obfuscation | 5 | eval(), getattr(), magic attributes, base64 encoding |
| Data Exfiltration | 5 | API keys, private keys, webhook URLs, database strings |
| Social Engineering | 3 | Authority impersonation, urgency manipulation, trust exploitation |
25+ detection patterns across 5 categories, supporting English and German attacks.
# Clone

The playground includes 9 pre-built attacks you can test with one click:
| Attack | Category | Difficulty |
|---|---|---|
| Direct Override | Prompt Injection | Easy |
| Role Play Escape | Prompt Injection | Easy |
| Delimiter Injection | Prompt Injection | Medium |
| Reverse Shell | Dangerous Commands | Hard |
| Eval Obfuscation | Code Obfuscation | Medium |
| API Key Exfiltration | Data Exfiltration | Medium |
| Authority Impersonation | Social Engineering | Easy |
| Synonym Override (DE) | Prompt Injection | Hard |
| Multi-Vector Attack | Combined | Hard |
The scanner is also available as a JSON API:
curl -X POST http://localhost:5000/scan \
-H "Content-Type: application/json" \
-d '{"text": "Ignore all previous instructions"}'Response:
{
"risk_score": 4,
"risk_label": "MEDIUM",
"is_safe": false,
"findings_count": 1,
"findings": [
{
"severity": "CRITICAL",
"category": "Prompt Injection",
"pattern_name": "Direct Override (EN)",
"match": "Ignore all previous instructions",
"line": 1,
"context": "Ignore all previous instructions"
}
]
