itinera-urban-citywalk-planner

Turn one free-text Citywalk request (e.g. "an itinerary full of history and art, some street wandering and bridge viewing") into a spatially-coherent, single-day POI-level urban itinerary. Decompose the request, retrieve candidate points of interest from a city POI dataset by embedding similarity, order them with cluster-aware spatial optimization (TSP over walking distance), then have an LLM write the day plan and render an interactive Folium map. Use when a user describes the *vibe* of a city walk in natural language and wants a personalized, walkable route through real POIs — not a generic multi-day trip with hotels and budgets.
