NeuPrompt
AI Prompt Sharing & Marketplace Platform
Overview
NeuPrompt is a full-stack web application developed for AI prompt sharing, organization, and discovery. User authentication is managed through Better Auth, providing secure Email/Password login and Google OAuth with persistent session control. Platform members can explore public AI prompts, perform search and category filtering, bookmark favorite prompts for quick retrieval, and publish custom prompt entries. To facilitate premium membership features, NeuPrompt integrates Stripe Checkout to unlock specialized prompt tools and exclusive content access. The system provides dedicated role-based dashboards for users and administrators to manage prompts, oversee site activity, and view billing history with downloadable PDF invoices generated on demand. Built with an Express.js and MongoDB REST API backend, NeuPrompt connects to a Next.js frontend built with HeroUI, Tailwind CSS, and Framer Motion.
