Agentic AI Travel Planner

Agentic AI Project

VoyageAI

Agentic AI Travel Planner

A full-stack AI travel planning platform that transforms destinations, dates, budgets, interests, and preferences into personalized day-by-day itineraries using grounded travel research, agent orchestration, deterministic validation, and automatic re-planning.

Agent Architecture

LangGraph workflow with context loading, external research, itinerary generation, validation, conditional routing, and bounded automatic re-planning.

Agent Workflow

Load ContextResearch TripGenerate ItineraryValidateRe-plan if Needed

Key Features

Stateful LangGraph workflow coordinates research, itinerary generation, validation, and bounded re-planning.
Uses external travel data for destination places and weather to ground itinerary generation.
Generates structured day-by-day itineraries based on trip dates, preferences, interests, and planning context.
Persists trips, itineraries, agent runs, agent steps, and tool execution data for observable AI workflows.
Interactive travel workspace combines itinerary, places, budget information, agent activity, and map-based exploration.
