Travel Planner turns a rough travel idea into a realistic, personalized trip plan by optimizing around actual traveler constraints, preferences, and destination realities rather than generic sightseeing lists. It gathers missing criteria, conducts live web research for time-sensitive facts like weather, visa requirements, and opening hours, and builds a balanced, geographically clustered day-by-day itinerary. Use it when planning itineraries, researching destinations, balancing pace, budget, and logistics, creating packing lists, or preparing a trip to be entered into Wanderlog.
