Question: I'm looking for a free travel planning service that helps me plan a dream vacation with minimal effort.

Guide is a great example of an AI-powered tool that generates personalized travel itineraries in mere seconds. It's got features like personalized itineraries based on your preferences, collaborative planning, integration with Expedia to book hotels, and real-time input from friends and family. Guide's recommendations, sourced from Lonely Planet and Google Reviews, are high quality, and it's good for all sorts of travelers.

Another good option is JourneyPlan, which will generate a personalized itinerary based on your input about destinations, travel time, budget and other factors. It's designed to be a smooth experience, factoring in things like safety, and you can share your plan with others. It doesn't yet offer direct booking for flights and hotels, but its AI-generated plans are very detailed and easy to modify.

For a more interactive approach, Vacay uses sophisticated AI technology and semantic search to offer customized travel recommendations and itineraries. It's got a chatbot interface for live suggestions, an interactive planner and curated local insights. It's got a free limited-access plan, but you can upgrade to Premium or Professional membership for more features.
