Parlant is an agentic workflow engine and orchestration framework designed for building conversational AI that adheres to strict behavioral guidelines. It provides a platform for managing multi-turn interactions through state-machine-based logic, allowing developers to define complex, hierarchical conversational flows that can adapt, skip, or revisit steps based on real-time user input.
The framework distinguishes itself through its focus on behavioral governance and observability. It enables developers to define precise domain terminology and enforce instruction compliance through prioritized guidelines, ensuring that agents remain consistent and brand-aligned. To maintain transparency, the system includes built-in reasoning audits and decision tracing, which log internal decision paths and guideline matches to help developers troubleshoot agent behavior and refine instructions.
Beyond core orchestration, the platform supports a wide range of operational capabilities, including tool execution middleware, dynamic data injection, and event-driven hooks for external integrations. It manages the full interaction lifecycle, from intent disambiguation and session context maintenance to frontend metadata attachment and response streaming. These features allow for the creation of context-aware interfaces that remain grounded in current information while providing a responsive user experience.
