Engineered for Developer Speed

Everything needed for low-latency, bulletproof content protection.

Multi-Model AI Failover

Gemini Flash • Perspective • HuggingFace • Pattern fallback. If any single AI service experiences upstream rate limits or downtime, requests seamlessly route down the chain without silent failures.

Sub-5ms Memory Caching

Repeat phrases, chat templates, and frequent comments resolve in under 5ms from local memory cache, reducing latency and slashing third-party compute costs.

Custom Rules & Rule Sets

Create custom blocked words, regex patterns, length thresholds, and sensitivity categories per project. Custom rules evaluate first to short-circuit before AI inference.
