WonderPlan

An AI-powered travel itinerary platform that generates fully personalized, day-by-day travel plans in under 3 seconds. Users describe their trip in natural language — the agentic backend handles flights, hotels, activities, and local dining in one pass.

Overview

WonderPlan started as a hackathon project and evolved into a full production application. The core is an agentic orchestration layer that decomposes a natural-language travel query into parallel sub-agents: one scrapes live hotel availability, another pulls activity data from a curated database, and a third generates a coherent narrative itinerary using GPT-4o. A collaborative mode allows travel groups to vote on itinerary suggestions in real time via WebSockets.
