Parlant is an open-source conversational AI engine developed by Emcie, committed to solving the Human/AI alignment problem by enabling LLMs to reliably perform as desired. It provides precise control over LLM outputs through structured utterances, contextual filtering, and a unique 'Fluid Composition' mode, directly addressing challenges like hallucinations in customer service AI. Parlant aims to make conversational AI tailored, reliable, and open, allowing developers to create deployable 'baseline agents' quickly, pre-equipped with conversation management, extensive logs, user input moderation, and jailbreak protection. The framework supports both open-source (HuggingFace) and OpenAI models, offering a plug-and-play RAG system for document-level Q&A, making it accessible for builders and data scientists.
