The AI Travel Agent is a production-grade, LangGraph-powered multi-agent system designed to streamline the entire travel planning experience. From researching flight options to booking hotels and delivering personalized itineraries via email, this intelligent assistant combines multiple language models (LLMs), real-time APIs, and human-in-the-loop decision making to help users plan trips with ease and control.
Built as a real-world demonstration of how LangGraph can be used to orchestrate dynamic agent workflows, this travel planner showcases the future of autonomous, yet collaborative, digital assistants.
Key Features
Stateful InteractionsThe agent remembers your preferences and prior inputs, enabling it to carry on conversations across sessions — no need to repeat your details.
You’re always in control. Before anything important is sent (like confirmation emails), the agent prompts you for approval. This keeps trust and transparency at the forefront of the experience.
Dynamic LLM SwitchingDepending on the task — whether summarizing data, invoking tools, or composing email copy — the agent selects the most appropriate language model. This architecture ensures both performance and contextual accuracy.
