This project provides a complete, production-ready example of an AI content generation application with integrated metered billing and subscription management. It's designed for developers looking to quickly implement usage-based pricing for OpenAI-powered applications, offering features like feature access control, usage reporting, and customer portals.

How It Works

The application leverages Next.js 13 with the App Router for its frontend and backend. It integrates Tier.run for managing subscriptions, metered billing, and feature access, decoupling these concerns from the core application logic. OpenAI is used for AI content generation, and Stripe handles payment processing. Authentication is managed via Auth.js, and Prisma serves as the ORM, with Vercel Postgres as the default database option.
