The tutorial covers building a full-fledged Quora clone using Strapi as the headless content management system and Next.js for the front-end. The project consists of five pages: login, home, answer, question, and account. Each page is built with reusable components, and the application uses AI-generated answers on the home page when no user-written answers are available. The tutorial also covers protecting against unauthenticated access to certain pages using middleware.
