What problem does it solve? Planning a trip involves juggling flights, hotels, entry requirements, pacing, and budgets across many scattered sources, and mistakes like missing visa rules or overpacked days can ruin the trip. ## Core Features & Use Cases - End-to-end trip planning: Gathers origin, dates, group composition, travel style, and priorities, then produces day-by-day itineraries with linked restaurants, activities, and transit. - Entry requirements and pacing rules: Checks visa, Schengen 90/180, ETIAS, passport validity, and vaccine requirements via web search, and enforces realistic pacing limits. - Interactive travel web apps: Builds map-plus-itinerary web apps with geocoding, PDF export via jspdf, budget tracking, packing lists, and deep links to Booking.com, Airbnb, OpenTable, and GetYourGuide. - Use Case: Ask for a 10-day Italy trip for a family with a baby, and receive a multi-region itinerary with flight options, hotel picks per city, stroller-friendly activities, budget breakdown, and a shareable web app. ## Quick Start Plan a 7-day mid-range trip to Japan for two adults departing from New York in April, including flights, hotels, and a day-by-day itinerary.
