The only Java AI framework with a complete prompt lifecycle (Dev → Test → Prod), built for creating complex agent systems and voice processing.
DriftKit is not just another library for calling LLMs. It's a full-fledged, production-ready platform that solves the real-world problems of integrating AI into business processes: prompt versioning, A/B testing, production monitoring, and building complex, manageable AI agents.
