A conversational AI server that manages agent behavior through context-aware guidelines, keeping responses consistent, auditable, and aligned at scale.

Parlant is a self-hostable conversational AI server designed for teams building customer-facing agents that need to stay on-brand, on-policy, and predictable in production. It sits between your frontend and your LLM provider, managing every interaction through a structured control layer rather than relying on monolithic system prompts or rigid intent graphs.
The core idea is context engineering: instead of stuffing all your rules into one prompt and hoping the model follows them, Parlant dynamically assembles only the rules, data, and tools relevant to each turn. The result is that the 200th behavioral rule is as safe to add as the first, with no degradation in adherence.
Key capabilities:
This is a meaningful departure from tools like Rasa or flow-based builders. Changing agent behavior is a content change (add or edit a guideline), not a structural one (rewire a graph). That makes it practical for product teams to feed ongoing feedback directly into the agent without requiring engineering intervention for every adjustment.
Parlant is LLM-agnostic and works with OpenAI, Anthropic, Azure, and others. It's built for enterprise AI teams where tone, edge cases, and policy constraints aren't afterthoughts.
