Itinerary Agent – AI Travel Planner

Link to repository

Inspired by ChatGPT, Wanderlog, and lightweight quiz-style apps.

Itinerary Agent is a web application that generates personalized travel itineraries using AI. Instead of manually searching through blogs, maps, and reviews, users answer a few quick quiz-style questions (destinations, interests, travel style, and preferences), and the app instantly produces a custom day-by-day plan.

The idea came from the challenge of information overload in travel planning. While platforms like Wanderlog and TripAdvisor are great resources, they often require extensive manual input or navigation. I wanted to create something simpler, more interactive, and powered by AI—to give travelers a fast, personalized starting point for their trips.

The long-term vision is to integrate this project into a broader microservices ecosystem alongside TravelBin and future applications, using JSON schemas and APIs to enable seamless data exchange and interoperability.
