Gemini, Google’s AI assistant, can plan detailed vacation itineraries by connecting to Google Maps, Hotels, and Flights for real-time data, including locations, reviews, and prices. It also pulls visual inspiration from YouTube creators and can integrate with the Viator app to book tours and activities. Gemini uses the context from a user’s prompt, such as destination, travel dates, and specific preferences like hidden-gem brunch spots. If Personal Intelligence is enabled in Google apps like Gmail, Photos, Search, and YouTube, Gemini can factor in interests, preferences, and constraints by securely connecting data across apps, past chats, and custom instructions. It can make personalized suggestions, such as restaurants based on saved food pictures or travel videos, and reference booked plans using flight details, hotel confirmations, and restaurant reservations from Gmail. Gemini can also remember interests and past picks to find new favorites and identify patterns across apps to recommend future destinations. The assistant understands how trip requirements like locations, travel times, existing plans, and personal preferences intersect when building an itinerary.
