Project Introduction

Summary

Parlant is an open-source engine providing tools and frameworks to model and manage conversations for Agentic UX, ensuring predictable and controlled interactions with LLMs.

Problem Solved

Addresses the inherent unpredictability and lack of control often associated with using raw large language models in conversational applications, enabling the creation of reliable and deliberate AI agents.

Core Features

Explicit Conversation Modeling

Define and structure conversation flows explicitly, guiding the LLM's responses within predictable patterns.

Tool Integration

Integrate external tools and data sources seamlessly into the conversational flow for contextually relevant and accurate agent actions.

Tech Stack

Python
LangChain (or similar orchestration)
YAML/JSON (for modeling)
Docker

Usage Scenarios

Parlant is ideal for scenarios requiring controlled, predictable, and deliberate conversational AI interactions, enabling the development of reliable AI agents across various domains.
