The most important and hottest keyword in 2025 and still in 2026.AI AGENT is.

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 speech; they 'think' for themselves, use 'tools,' and 'solve' problems.

1. Understanding the goal: Receives the command, "Please create a sales report for our company this month."

2. Strategy planning: It independently plans, 'I need to import Excel data, create graphs, and format the report accordingly.'

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

Simply put:> The AI Agent has evolved from "someone who tells you how" to "someone who delivers the result."

2. Why is the AI Agent an 'essential survival skill'?

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

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

• 24-hour operation: It completes tasks on its own, thinking independently without ever sleeping.

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

• "Many people give up here, saying 'AI Agents are still premature,' and go back to doing things by hand."
  
  

You put a lot of effort into crafting prompts, but all you get back are plausible-sounding lies. As you review and correct them one by one, you end up thinking this.'It would be faster if I just typed it myself instead of reviewing all this.' You tried to save time by using AI, but end up exhausted by the ironic situation of spending even more time cleaning up after the AI.

"But I assure you, it's not because the AI is stupid. It's because the practitioners didn't provide a 'workflow (blueprint).'"

Learning how to design this 'loop of reasoning,' where AI performs and verifies tasks on its own, is the core skill of the intermediate course.

"After mastering the beginner course and ambitiously applying it to real work... didn't you hit a wall at some point?" Please take each step carefully, from the intermediate course to the advanced course that will be released later.

1. VOD

See with your eyes, practice with your hands, and create your own: Our learning philosophy.

Fragmented knowledge and simple 'follow-alongs' cannot build real skills. Our goal is for you to become a 'creator' who freely commands AI and produces your own results. To achieve this, we have designed the most effective learning experience.

A. Systematic and in-depth VOD, free viewing

Beginner + Intermediate: Over 12 VOD lessons. Instead of fragmented tips, we provide a systematic curriculum to solidify your AI skills from the ground up.

Unlimited repeat access: Whether you are a busy professional or a student, you can watch as many times as you want, whenever you want. Revisit difficult parts and quickly find what you need to fully absorb the content as your own.

B. Mastery of Knowledge: 3-Step Practice-Based Learning Method

There is a professional "sense" that cannot be learned from text alone. Nothing is more effective than seeing exactly when and how to use AI tool buttons and what results appear in real time. That’s why every lesson is structured with the following 3-step practice process.
Step 1: Understanding Core Concepts: Before any practice, we clearly explain the essential basic concepts—why this feature is needed and how it works.
Step 2: Live Practice Demonstration: Next, we vividly show the entire process of using AI tools through video. Even complex E-Book content becomes easy to understand after watching the video lectures.
Step 3: Creating Your Own Work: The ultimate goal of the course is not just to "follow along." It is to create your own content based on the principles you have learned. Through this process, you will truly become a "creator."

C. Optimal Synergy: VOD Lectures and E-Book Guide

We create the best synergy through two types of learning materials.
VOD Lecture (Video): "How to" This is a practical video showing you how it’s done. Learn intuitive skills and know-how by watching the expert’s workflow.
E-Book Guide (E-Book): "Why" This is a theoretical compass that explains why you should do it that way. Deepen your understanding and application by reviewing what you learned in the videos.
Through this process, you will no longer be a passive learner simply following along, but an "AI expert" who solves problems independently and discovers your own ways to use AI.

This is part of the content from Lesson 2 of the Agent Course Beginner Edition.

2. E-book

Six AI textbooks in your hands: E-Book

Every lesson comes with anE-BOOK that contains only the essential theories and practical tips in a condensed format. You can quickly review and reference what you learned in the videos while on the go or at work. No more worrying about forgetting important information. Your reliable knowledge base for growth is always with you.

A. Synergy between Navigation (VOD) and Detailed Map (E-Book)

Our learning materials are designed to create the best synergy.

VOD Lecture: Shows the process of using AI tools in real time and guides you along the way.‘Navigation’ It allows you to quickly acquire intuitive skills and know-how by observing the expert's workflow.

Two E-Books: These are 'detailed maps' containing all routes, terrain information, and even hidden shortcuts. They add depth and breadth to the practical sense you gain from the videos.

B. Everything from experts that couldn't be included in the videos

E-Book is not just a summary of the video content. It contains deeper and more detailed information that could not be covered in the lectures due to time constraints.

Deeper principles: It provides a detailed explanation of the underlying principles and background knowledge of each function that were omitted in the lectures, helping you fundamentally understand 'why' it works that way.

Additional expert tips: It is packed with extra tips and problem-solving know-how that only the instructor knows and can be immediately applied in practice.

Advanced usage and cases: Beyond the basics, it presents advanced strategies and various real-world examples to help you produce higher-level results by applying what you have learned.

C. Our promise: We will make you an 'advanced-level' expert.

To be honest, if you master practical skills through the video lectures and absorb all the details with the two E-Books,your AI utilization skills will no longer remain at the 'beginner' level.

Becoming someone who can confidently say they can handle AI anywhere,We promise to take full responsibility for helping you grow into an expert at a 'considerable level.'

The E-Book table of contents and structure may be subject to change.

[Important Notice] Information regarding the use of paid AI tools.

For the best learning experience and quality of results, our AI class requires the use of paid versions of major AI tools. The course fee does not include the monthly subscription fee for AI tools, which must be paid separately. Just as you need a good knife to cook well, investing in the best-performing tools is the fastest way to learn and utilize AI properly.

1. Why do we need to use paid AI tools?

The difference between the free and paid versions of the latest AI tools is not just a matter of 'a few features.' Like the difference between a compact car and a sports car, there is an overwhelming gap in the performance and speed of the underlying AI models, as well as the quality of the results.
We hope you learn how to use 'professional tools,' not 'toys.' Using paid tools is an essential investment to make the most efficient use of your valuable time and effort, producing the best possible results.

2. Clear limitations of the free version: Four factors that hinder learning

Free AI tools are merely a taste, and there are clear limitations to full-scale learning and practice as follows.
1. Core features and AI model performance
Free version: Based on outdated AI models (e.g., ChatGPT 5.4), it produces inaccurate or uncreative results.
Paid version: Uses the latest high-performance models (e.g., GPT-5.4, Gemini3.0) to deliver much more accurate, professional results and fully understand complex requirements.
2. Speed and usage limitations
Free version: During peak times, responses are very slow, and frequent usage restrictions often disrupt the flow of practice.
Paid version: Priority processing ensures a smooth and fast experience, and generous usage allows you to implement your ideas without limitations.
3. Quality and commercial use
Free version: Results may have watermarks or be provided in low resolution, and commercial use is often prohibited, limiting their use in portfolios.
Paid version: High-quality results without watermarks and commercial usage rights provide a foundation for turning your creations into profit.
4. Motivation and learning drive
Free version: When you repeatedly get slow, blocked, and low-quality results, your motivation to learn quickly fades and you become easily exhausted.
Paid version: The 'success experience' gained from fast and powerful performance becomes the most important motivation for consistent learning.

Now, the choice is yours.

Right now, there are two clear paths before you. This choice is not simply about picking a single course. It is a 'choice for the future' that will determine who you are in 1, 5, or 10 years.

1. Two paths: Those who command AI vs. those who give their jobs to AI

• The path of those who command AI: While others struggle for days, you finish tasks in just a few minutes and dedicate your extra time to more creative work, achieving overwhelming results. Thanks to AI, your value continues to rise, and endless opportunities await in the future.

• The path of those who give their jobs to AI: By ignoring the flow of change and stubbornly sticking to familiar ways, you will eventually be replaced by AI and those who know how to use it. Your place in the world will shrink, and anxiety about the future will only grow.

2. We will answer your final hesitation.

• The fear of thinking, "I understand... but can I really do it too?": Instead of vague theoretical lectures,Practice-oriented lectures will be our answer. We guide you to create tangible 'results' that can be immediately applied to your work and life. Visible outcomes spark interest, and theory becomes easier to grasp.
  
  

• The burden of "98,000 won": Of course, it can feel like a lot. But this amount disappears after a few meals out or a couple of months of phone bills.'Consumption'. On the other hand, investing in this course is the most certain and profitable'Investment' you can make to multiply your value dozens or even hundreds of times.

3. The fastest way is to 'start now.'

Your competitors are already equipped with the powerful weapon of AI and are running ahead. Do not postpone your limitless potential by saying 'later.' End your hesitation and take the first step toward your future. Go beyond repetitive tasks, create what no one has imagined, open new career paths, and prove your value.

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

We will take the first step of AI learning 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 your future,First, you need to get started.

Beyond technology, insight into the times: A guide for wise pioneers in the age of AI.

The word AI has now become a symbol representing not just technology, but a massive transformation of our era. Are you ready to become the protagonist of this great journey? We will take that first step with you.

1. Why do we focus on 'AI utilization': The story of two founders.

Our two CEOsWorld-renowned AI institution, Zhejiang University (Ranked No. 1 globally) worked alongside AI technology leaders such as the founder of Deepseek atand learned the unique spirit of collaboration called 'Podan Entrepreneurship (抱团创业)'. After returning to Korea and going through countless projects over five years, we gained one conviction.

The true opportunity in the AI era does not lie solely in technology development (R&D) itself. Just as Microsoft created Windows, but even more added value was generated by the applications built on top of it, the same is true for AI. Creating the wave yourself is not the only answer.If you learn how to ride the giant wave, you can sometimes go even further than those who created it. We have focused all our capabilities on exactly that—'AI utilization' and 'business creation.'

2. This course is an 'AI Field Manual for Practice.'

Amidst the flood of information, many people feel lost about what, how, and where to start with AI. This course and E-Book are not vague theoretical books. They are a 'practical field manual' built from years of hands-on experience with AI and automation systems in various projects in the domestic online market.

Our goal is clear. We want to make AI not an unknown entity, but the most powerful 'strategic partner' to maximize your intelligence and experience.

3. From a 'doing' person to a 'designing' person.

You should not remain at the level of simply 'doing' assigned tasks faster with AI. This course will shift your way of thinking, enabling you to use AI to'design and create' new value. It will help you become a person who does so. AI will become a megaphone that amplifies your thoughts and a tool to realize your imagination.

4. The era of Wise Pioneers—You are the protagonist.

The history of the AI era will be recorded not only by the few geniuses who created the technology, but also by the 'Wise Pioneers' who first recognized its potential, skillfully utilized it, and created new wealth and opportunities.

Through the practical knowledge and AI utilization methods we have accumulated,We will help more people become the protagonists of this great journey.

"Why Wadiz?"

"Corporate consulting know-how worth tens of millions of won, revealed at this price only on Wadiz."

In fact, this 'AI agent design' know-how has only been provided as high-priced B2B consulting or solutions for companies. For the general public, the technical barriers and costs were too high to access.

However,2026 is the first year of 'AI agent popularization' We were confident that Wadiz supporters, who are quick to recognize change, would appreciate the true value of this technology. We decided to launch this on Wadiz funding to put the '24-hour unmanned automation system,' once exclusive to companies, into your hands under the most reasonable conditions.
