NeuTrip
AI-Powered Travel Planning Platform
Overview
NeuTrip is a production-ready travel planning web application built to deliver an intuitive end-to-end trip organization experience. The platform allows users to manage itineraries seamlessly while benefiting from an integrated AI-powered support assistant. Authentication is handled securely through Better Auth, supporting both standard Email/Password credentials and Google OAuth alongside persistent session management and protected routes. To provide contextual, real-time guidance, NeuTrip incorporates a multilingual AI chatbot trained on custom documents, PDFs, and website resources. The application is built on a decoupled architecture, pairing a Next.js frontend with an Express.js and MongoDB Atlas REST backend. Media management is handled via ImgBB, and the system is deployed to production with the frontend hosted on Vercel and the backend running on Render.
