Get 200% Out of the Paid Version of ChatGPT: Practical Codex for Controlling My Computer!

ChatGPT, which used to only answer questions, now works directly on my computer. I give it instructions in Korean without typing a single line of code and receive the results as files. This six-part series, including the orientation, explains Codex’s workflow of context, planning, execution, and deliverables, then covers everything from safely defining a working folder to organizing files, creating tables with sources, and setting up scheduled executions that run automatically at a specified time.

"What was most important in 2025 and in 2026

It is also the hottest keyword, AI AGENT."


1. What exactly is an AI agent?



'LLM Chatbot' vs. 'AI Agent'


Let's compare them using 'travel' as an example.



AI agents go beyond simply understanding language: they independently 'think,' retrieve 'tools,' and 'solve' problems.


  1. Understanding the goal: It receives the command, "Please create our company’s sales report for this month."

  2. Strategy planning: It makes a plan on its own: 'I should import the Excel data, create a graph, and then format it according to the report template.'

  3. Direct execution: It actually opens the Excel file, launches PowerPoint, completes the report, and delivers it to the user.


Simply put: > AI agents have evolved from “entities that tell you how” to “entities that deliver the finished product.”


2. Why Is AI Agent a “Survival Essential Skill”?

In the past, countless people had to work through the night to make hundreds of projects successful. But now, a single well-trained AI agent can do the work of ten people.

  • Save time: Delegate repetitive paperwork and data collection to AI so people can focus only on more important decisions.

  • 24/7 operation: It thinks independently without sleeping and completes tasks on its own.

  • Revenue generation: You can run business processes at an enterprise level at a low cost.



  • "Many people give up here, thinking, 'AI agents are still premature after all,' and go back to doing the work manually."

You carefully crafted the prompt, but all you got in return was a plausible-looking lie. As you review and correct it piece by piece, you eventually find yourself thinking, 'It would be faster to just type this myself than spend time reviewing it.' You tried to save time by using AI, but instead, you end up exhausted by the irony of wasting even more time cleaning up after it.

"But I can say with certainty that it's not because AI is stupid. It's because those practitioners didn't provide a 'work sequence (blueprint).'"


The core skill of the intermediate course is learning how to design AI so that this “loop of reasoning,” in which it performs tasks and verifies its own work, is possible.

"Have you ever mastered the beginner course and ambitiously applied it to real-world work, only to hit a wall at a certain point...?" Please take the steps one by one, from the intermediate course through the advanced course to be released later.




1. VOD

See it, practice it, and create something of your own: Our learning philosophy

Fragmented knowledge and simply following along are not enough to build genuine skills. Our goal is to help you become a “creator” who can use AI freely and produce your own results. To achieve this, we have designed the most effective learning experience.

A. Systematic, in-depth VOD with flexible viewing

VOD: Rather than fragmented tips, our systematic curriculum will build your AI skills from the ground up.


Unlimited repeat viewing: Whether you’re a busy professional or a student, you can watch the course as many times as you like, whenever you want. Review difficult sections and quickly find the parts you need to fully make them your own.


B. Completing Your Knowledge: A Three-Step Practice-Oriented Learning Method

There is an expert’s “feel” that cannot be conveyed through text alone. Nothing is more effective for learning than directly seeing when and how to click buttons in AI tools and what results appear in real time. That’s why every course is structured around the following three-step, hands-on learning process.
Step 1: Understanding the Core Concepts: Before any hands-on practice, we clearly explain the essential foundational concepts, including why each feature is needed and the principles behind how it works.
Step 2: Live Hands-On Practice You Can See: Next, we vividly show the entire process of using AI tools ourselves through video. We designed it so that even the complex content in the E-Book becomes easy to understand—after watching the video lecture first, you’ll think, “Ah, so that’s what this is about!”
Step 3: Creating Your Own Work: The ultimate goal of the course is not simply to “follow along.” It is to create your own content based on the principles you have learned. Through this process, you will be reborn as a true “creator.”


C. The Best Synergy: VOD Lectures and E-Book Guide

We create the best synergy through two learning resources.
VOD lectures (video): “how” Practical videos that show you how to do things. By observing experts’ workflows, you develop an intuitive sense and learn valuable know-how.
E-Book guide (digital book): “why” The theoretical compass that explains why things should be done that way. By reflecting on what you learned from the videos, you develop a deeper understanding and the ability to apply it.
Through this process, you can become an “AI expert” who solves problems independently and discovers your own ways to use AI, rather than a learner who passively follows the lectures.


2. E-book

A Textbook in Your Hands: E-Book

Every course comes with an E-BOOK packed with only the key theories and practical tips. You can quickly review and refer to what you learned in the videos while on the go or at work. No more worrying about forgetting important information. A reliable knowledge repository that supports your growth is always by your side.

A. The synergy between the navigation (VOD) and detailed map (E-Book)

Our learning materials are designed to create the greatest synergy.


VOD lectures: A “navigation system” that guides you by showing you how to work with AI tools in real time. By watching experts’ workflows, you can quickly develop an intuitive feel and learn practical know-how.


E-Book: A “detailed map” containing every route and terrain detail, including hidden shortcuts. It adds depth and breadth to the practical skills learned from the videos.


B. Everything from the Expert That Couldn't Fit in the Video

The e-book is not merely a summary of the video content. It contains deeper, more detailed material that could not be covered in the course due to time constraints.


Deeper Principles: We provide detailed explanations of the in-depth operating principles and background knowledge of each feature that were omitted from the course, helping you fundamentally understand “why” they work that way.


Additional expert tips: We’ve packed in valuable tips and troubleshooting know-how that only instructors know and that you can use right away in real-world work.


Advanced Techniques and Examples: Going beyond the basics, we present advanced strategies for applying what you’ve learned to create higher-level results, along with a variety of real-world examples.


C. Our promise: We will turn you into an expert at a ‘considerable level.’

To be honest, if you have developed a practical feel through the video lectures and absorbed every detail from the two E-Books, your ability to use AI will no longer remain at a 'basic' level.


We guarantee that you will grow into a “highly capable” expert who can confidently say you know how to use AI anywhere.



[Important Notice] Information on Using Paid AI Tools

For the best learning experience and highest-quality results, our AI class requires the use of paid versions of the major AI tools. The tuition fee does not include the monthly subscription fees for the AI tools, which must be paid separately. Just as you need a good knife to prepare good food, investing in tools that deliver the best performance is the fastest way to learn and make proper use of AI.


1. Why should you use paid AI tools?

The free and paid versions of the latest AI tools differ by more than just a few features. Just as a compact car and a sports car differ, there is a dramatic gap in the performance and speed of the underlying AI models and the quality of the results.
We want you to learn how to use a “professional’s tool,” not a “toy.” Using paid tools is an essential investment for making the most efficient use of your valuable time and effort to create the best possible results.


2. The Clear Limitations of the Free Version: 4 Factors That Hinder Learning

Free AI tools are merely a taste, and they have the following clear limitations when it comes to serious learning and practice.
1. Core Features and AI Model Performance
Free version: Based on older AI models, it produces inaccurate or less creative results.
Paid version: Uses the latest high-performance models to deliver much more accurate and professional results while perfectly understanding complex requirements.
2. Speed and Usage Limits
Free version: During peak usage hours, responses can be extremely slow, and frequent usage limits often disrupt the flow of practice.
Paid version: Priority processing ensures a smooth and fast experience, while generous usage allowances let you freely bring your ideas to life without restrictions.
3. Quality and Commercial Use
Free version: Results may include watermarks or be provided in low resolution, and commercial use is often prohibited, limiting their use in portfolios as well.
Paid version: Provides high-quality, watermark-free results along with commercial usage rights, serving as a foundation for turning your creative work into revenue.
4. Learning Motivation and Drive
Free version: When slow, blocked, and low-quality results continue to pile up, your motivation to learn can quickly fade, leaving you exhausted in no time.
Paid version: The 'success experiences' gained through fast and powerful performance become the most important motivation for sustaining consistent learning.



Now, all that remains is your choice.

Two clear paths now lie before you. This choice is not simply a matter of selecting a course. It is a “choice about your future” that will determine who you are 1, 5, and 10 years from now.

1. Two Paths: Those Who Command AI vs. Those Who Give Their Jobs to AI

  • The path of those who command AI: They complete tasks that take others days of struggle in just a few minutes, devote the time saved to more creative work, and achieve overwhelming results. Thanks to AI, their value continues to rise, and opportunities keep coming their way in the future.

  • The path of those who give their jobs to AI: By turning a blind eye to the tide of change and clinging only to familiar methods, they ultimately get replaced by AI and the people who know how to use it. It is a future where their place becomes narrower and narrower, and their anxiety continues to grow.


2. We’ll address your final hesitation.

  • "I understand... but can I really do it too?" The fear: We will answer with a hands-on, practice-focused course, not a theoretical lecture full of abstract concepts. We will guide you in creating tangible "results" that can be applied immediately to your work and life. Seeing visible results sparks interest and makes the theory easier to understand.

3. The fastest path is to ‘start now.’

Your competitors have already equipped themselves with the powerful weapon of AI and are racing ahead. Don’t postpone your limitless potential by telling yourself, “later.” End your hesitation and take the first step toward the future. It’s time to go beyond simply repeating routine tasks, create what no one has imagined, open up a new career, and prove your value.

Now, become the 'master' who gives instructions to AI.

We’ll take the first step in learning AI together with you.

It doesn't have to be our course. However, the day will soon come when most tasks cannot be done without AI. For the sake of your future, you need to get started first.


Insight Beyond Technology: A Guide for Wise Pioneers of the AI Era

The term AI has now come to symbolize not just technology, but the great transformation of our era. Are you ready to become a leading figure in this remarkable journey? We will take the first step together with you.

1. Why We Focus on ‘AI Application’: The Story of Two Entrepreneurs

Our two founders studied at Zhejiang University, a world-renowned AI powerhouse (ranked No. 1 globally), alongside AI technology leaders such as the founder of DeepSeek, and learned the unique spirit of collaborative entrepreneurship known as “抱团创业”. After returning to Korea and working on countless projects over five years, we came to one firm conviction.

The true opportunities in the AI era do not lie solely in technology development (R&D) itself. Just as Microsoft created Windows, but more added value was generated by the applications built on top of it, the same is true of AI. Creating the waves yourself is not the only answer. If you learn how to ride a giant wave, you can sometimes go farther than the person who created it. We have focused all our capabilities on precisely those areas: ‘how to leverage AI’ and ‘creating businesses.’

2. This course is an “AI Practical Field Manual”

Amid the flood of information, many people feel overwhelmed, unsure of what to do with AI, how to use it, or where to begin. This course and E-Book are not abstract books of theory. They are a “practical field manual” built over the past several years through our hands-on experience applying AI and automation systems to various projects in Korea’s online market.

Our goal is clear: to turn AI from an unknown entity into the most powerful “strategic partner” for maximizing your intelligence and experience.

3. From ‘Doing’ to ‘Designing’

You must not remain at the level of simply ‘processing (doing)’ assigned tasks faster with AI. This course will transform the dimension of your thinking and help you become someone who uses AI to ‘design and create’ new value. AI will be a megaphone that amplifies your thoughts and a tool that brings your imagination to life.

4. The Age of Wise Pioneers—you are the main character

The history of the AI era will be written not only by the few geniuses who created the technology, but also by the “Wise Pioneers” who first saw through its potential, used it most skillfully, and created new wealth and opportunities.

Through the practical knowledge we have accumulated and our methods for leveraging AI, we will help more people become the protagonists of a great journey.
