Did you just tell the AI,
'
Make me an OO site'?


AI coding agents have learned not only a human developer's code but also their collaboration style.
Just as you wouldn't simply ask a human developer to 'make XX,'

💬 To create a high-quality product, you need to assign roles to each coding agent and engage in 'communication' by requesting them to collaborate based on clear standards.


We will complete the PRD (Product Requirement Documents), which serves as the functional specification for the service, together with the AI development team to create a profitable service with a clear sense of direction.

Writing Clear PRDs

Meticulous PRD writing

You will directly design the PRD planning document, UX Flow, DB Schema, and API structure,
and experience full-stack Vibe Coding from developing full-stack capabilities such as social login, PG payment API, and admin pages
to actual service deployment.

In the end, large-scale profits are

Not from advertising revenue, but from payment revenue!


The core of this lecture - Payment revenue!

You can generate the same amount of ad revenue that would require 10,000 visits worth of traffic with just a single payment transaction.
When you smartly solve a consumer's specific pain point, customers will gladly pay to use your service.


Instead of the labor of using clickbait to draw in daily traffic,
try creating a product you want to show off that solves real problems and provides real value!

Experience the entire process of developing a real-world monetization service, from planning and automatic product generation using Next.js-based AI Agents,
Toss Payments integration, to deployment via Github and Vercel.

💼

Just like a commercial service,
from the admin dashboard to security and optimization


Revenue Dashboard Admin Page

Order Management Admin Page

Telegram bot for order and creation failure notifications

It doesn't just end with creating the service.

Services that consistently generate revenue require continuous management like a living organism.
We will build admin pages for managing sales, orders, and users just like a real commercial service.

When an order is placed, you will receive an order history notification via your Telegram bot, and if an LLM service fails to be created, you will be notified immediately, allowing for customer service response.


The biggest weaknesses of Vibe Coding using AI are security and performance optimization.

As this is a service where payments occur, we launch the service after meticulously testing compliance, including customer privacy protection, performance optimization, and the inclusion of commercial terms and conditions.


Of course, we also conduct thorough E2E testing of the features we implemented to improve the quality of the product.

Frequently Asked Questions (FAQ)

Q. I don't know anything about coding; can I still follow along? ⌨️

Yes, this course is designed to build a site by giving prompts to an AI coding agent rather than typing the code yourself. However, you will be able to proceed more smoothly if you take the <12 Introductory Guides for Non-Majors to Develop Profitable Web Services in the AI Era> course first.

Q. Does the completed site actually generate revenue? 💸

Yes, you will build a high-quality site that is actually deployed and enables real payments through Toss Payments. However, since simply creating the same site does not guarantee profit, we provide support at the Kobaetu Offline One-Day Hackathon to help you launch by incorporating your own unique service ideas.

Q. Can I apply this to other profitable services after completion? 💡

Yes, that is the core value of this lecture. By utilizing the PRD template and the 'Payment → AI Generation → Result Delivery' structure completed in the course, you can create various AI-based digital content sales sites such as MBTI analysis, tarot reading, AI fortune telling, and character matching.

Q. Are there any additional costs besides the lecture fee? 💳

Most tools are free. Antigravity, Next.js, TypeScript, Tailwind CSS, Supabase (free tier), Gemini (free credits), GitHub, Vercel (free tier), and Telegram bots are all free. Items that may incur costs in the future are as follows:

- Toss Payments: Transaction fees per payment (Business registration required, starting from the practical course)

- Domain: 10,000 to 20,000 KRW per year (Optional)

What will be covered in the lecture


Section 1 - Setting up the Basic Environment for a Paid Web Service

With the goal of building a profitable web service where actual payments occur, you will learn how to effectively utilize an AI development team and build a foundation in necessary AI tools and MCP (Model Context Protocol). You will also learn how to give clear instructions to agents.

Section 2 - Initial Setup of AI Agent Development Environment and Deployment Configuration

Initial setup of essential AI agent development environments such as Github, Supabase, Toss Payments, and Context7 will be performed, and project coding style guides will be established. Additionally, an efficient deployment process using Github and Vercel will be configured.

Section 3 - Assigning Tasks to Frontend/Backend Planners

Utilize AI agents as web planners to design the user interface (UI) and user experience (UX) flow. Collaborate with AI to write detailed specifications for frontend and backend development.

Section 4 - Assigning User Service Tasks to Frontend Developers

Utilize AI agents as frontend developers to implement core user-centric features such as global layout, main landing page, product details, payment, feeds, interpretation verification, login, and My Page. Enhance the quality of the application through frontend end-to-end (E2E) testing.

Section 5 - Assigning User Service Tasks to the Backend Developer

Utilizing the AI agent as a backend developer, we develop core service features such as basic server and DB setup, social login, PG payment, and order creation and update APIs. We ensure stability through backend end-to-end (E2E) testing.

Section 6 - Assigning Admin Service Tasks to Frontend Developers

Utilizing AI agents, we will configure the global layout of the admin page and implement core admin functions such as sales, orders, and user management. We will then perform frontend end-to-end (E2E) testing to verify the completeness of the admin features.

Section 7 - Assigning Admin Service Tasks to the Backend Developer

Utilize AI agents as backend developers to develop the APIs required for admin functions such as sales, orders, and user management. Verify the data processing and management logic of the admin functions through backend end-to-end (E2E) testing.

Section 8 - Assigning Tasks to Optimization and Security Experts

Collaborate with AI agents to perform the roles of security development, performance optimization, and compliance experts. This further enhances the stability and completeness of the developed web service.


AI Development Team Completion with

Real monetized payment web service

Point 1. Building a real monetized web service with AI

You will operate an AI development team just like a human team to build an 'AI-commentary product shopping mall' yourself. Through the experience of building a service where actual payments occur, you can solidify the fundamentals of a monetized web service. Gain confidence based on the experience of the 'One-Month Launch Challenge.'


Point 2. Complete Experience of Practical Work Processes

Go beyond simple clone coding and experience the entire process of actual web service development, from planning to deployment. You can strengthen your practical skills by manually designing PRD planning documents, UX flows, DB schemas, and API structures. Experience efficient development through the 'MCP' system utilizing coding agents.


Point 3. Improving AI Agent Utilization Skills

You will learn how to build a system where AI automatically generates content through LLM API integration. You can acquire the know-how to obtain desired results by delivering a clear 'service specification' to the AI agent. You will master how to assign tasks to each specialized AI development team (Planning, Frontend, Backend).


Point 4. Implementation of Infinite Inventory and Zero Cost Services

Implement a side project that can be quickly validated through an AI-powered commentary product shopping mall with 'infinite inventory and zero cost.' Gain experience with a service that generates actual payments by integrating Toss Payments, and complete your own profitable web service.
