Travel Agent AI leverages large language models and travel APIs to automate the process of trip planning and booking. Users input their travel dates, destinations, budget, and interests; the agent then produces a day-by-day itinerary with recommended flights, hotels, and local attractions. It uses real-time API calls to check flight schedules, hotel availability, and weather forecasts. Features include customizable itineraries, cost breakdowns, multi-city routing, and suggestions for dining and transportation. Designed for both casual travelers and travel professionals, Travel Agent AI reduces manual research, optimizes travel costs, and provides a comprehensive travel plan in minutes.
