11-Layer Defense
Security That Actually Works
Most AI security tools check for keywords. CleanPrompt analyzes intent, detects hidden attacks, and understands context - catching threats others miss.
Injection Detection
Catches prompt injections, jailbreak attempts, and system override attacks using pattern analysis and behavioral signatures.
Unicode Attack Blocking
Detects hidden payloads in Zalgo text, Unicode tags, homoglyphs, and invisible characters that bypass other filters.
Social Engineering Guard
Identifies manipulation tactics like urgency, authority claims, secrecy requests, and emotional exploitation.
Intent Classification
Classifies prompt intent across 10 categories from harmless queries to data extraction attempts with risk scoring.
Context-Aware Scanning
Distinguishes gaming, fiction, and educational contexts to reduce false positives while maintaining security.
Sensitivity Controls
Adjustable strict/balanced/permissive modes let you tune detection thresholds for your specific use case.
