CityLink

Inspiration

CityLink was born from a simple idea: traveling is better when shared. Exploring new places can be exciting but also overwhelming, especially when traveling solo. We wanted to build a platform that not only helps travelers discover the best spots but also connects them with like-minded adventurers heading to the same destinations. With the power of AI and real-time communication, CityLink transforms every trip into a shared journey, making travel more social, collaborative, and personalized.

What it does

CityLink enhances the travel experience by allowing users to search for destinations with Google Maps API suggesting nearby cities. Once a destination is selected, travelers are automatically placed in a real-time chatroom with others visiting the same location. AI-powered recommendations help users discover top attractions, must-visit restaurants, and hidden gems. Additionally, a built-in chatbot refines these suggestions based on user preferences and provides direct links to Google Maps for easy navigation. Whether users want to find local experiences, ask for recommendations, or meet fellow travelers, CityLink fosters a seamless and engaging way to explore.

How we built it

We built CityLink using modern web technologies and cloud infrastructure. The frontend is developed with React.js, featuring Google Maps API integration for dynamic location-based searches. The backend is powered by Python and Flask, real-time chat functionalities through Web-Socket API, and AI-powered recommendations. Redis is used for messaging storage, ensuring a smooth and responsive chat experience. The AI recommendation system leverages OpenAI’s API to generate personalized travel and dining suggestions based on user inputs.
