Parlant is an open-source conversational AI engine for building reliable, production-grade chat agents. It lets developers create customer-facing AI agents that consistently follow defined guidelines across complex interactions—without relying on brittle prompt engineering or flow-based logic. Instead, agents are shaped through behavioral “guidelines” that trigger actions (like calling tools or routing to a human) under specific conditions, ensuring compliance and explainability.
Designed for regulated or sensitive use cases—such as financial services, healthcare, legal, and government—Parlant empowers teams to build, refine, and monitor AI agents with structured principles, conversational journeys, tool integration, and contextual control. It logs every decision, supports rapid iteration, and is backed by contributors from Microsoft, Check Point, Weizmann Institute, and industry engineering teams. Parlant is available under the Apache 2.0 license, with active development through v3.0 and a community-maintained GitHub repository.
Parlant is developed by Emcie Ltd.
