I am a non-developer. One-liner: "I feel like I'll actually be able to build what I need using CODEX after taking this course." --- (From a non-developer's perspective) You can learn how to use Codex. Before taking the course, I heard that you could 'build what you want' by connecting Codex to GitHub, but when I actually tried it, the process was so difficult that I gave up. Through this course, you can get many hints on how to utilize CODEX through examples rather than just theory. It was great to learn things like, 'I can even do "automation," such as receiving articles every morning, using GitHub' (and realizing, 'So this is how developers use it so much'). However, it would be even better if you have some prior knowledge of the terminology used by developers. The instructor does explain the words developers use, but I am personally bridging the gap between the expert and a non-developer by having separate conversations with ChatGPT to supplement the parts I lack.

For those who have been developing for a long time or are already familiar with using AI, this may feel somewhat basic. However, it consists of various hands-on projects using Codex, including a Funding Fee dashboard for a cryptocurrency exchange, so it would be a good course for those interested in this field. Rather than focusing on technical aspects, it seems to cover only the essentials of vibe coding, with the key being how you apply and incorporate the instructor’s know-how. If you are already familiar with the subject, it may be a good idea to skip the earlier sections and start with the hands-on exercises. I felt this course would be especially suitable for those who are encountering practice environments such as Codex App, Codex Cloud, and Codex CLI for the first time and want to become familiar with them through hands-on work. It also includes practical sections on automating office tasks and using Codex App Server, so I would recommend it to those who are just starting to learn programming and want to develop a feel for it through practice.

“A lecture that helped me master vague AI coding through actual projects” I was interested in AI-powered coding but didn't know where to start. Through this lecture, I was able to learn step-by-step, from the basic flow of utilizing OpenAI Codex to methods for applying it to real projects. I especially liked that it wasn't just about explaining features, but was structured around projects where I could create actual outputs, allowing me to immediately verify and apply what I learned. At first, I thought ‘Vibe Coding’ was simply a way of asking AI to write code for me. However, through the lecture, I realized that everything from writing prompts to get good results, to reviewing and modifying the generated code, and the process of resolving errors is all important. The explanations were friendly enough for beginners to follow, yet I was satisfied that it covered advanced content applicable to practical work as it progressed. I believe this lecture gives those with little coding experience the confidence to start development using AI, and offers existing developers a new way to increase work speed and productivity. I would recommend it to anyone who wants to systematically learn OpenAI Codex and Vibe Coding.
Full OpenAI Codex Workflow - How to choose and use Codex App (VS Code IDE extension), Codex Cloud, and Codex CLI for different situations
Vibe Coding Fundamentals: The practical routine of “Requirements → Prompt → Design/Plan → Implementation → Execution/Verification → Refactoring/PR”
Scaling Workflow Automation with Skills: Installing and Utilizing Built-in and Additional Skills
Practical Automation Through Projects: How to Reduce Repetitive Tasks by Entrusting "Documents/Reports/Web Tasks/Code Management" to Codex
Peter Steinberger, the developer of OpenClaw, used voice conversation through a speaker to
The appearance of calling multiple Codex agents to proceed with development in parallel
This course is a practical curriculum designed to help you gain the experience of completing a project through Vibe Coding using OpenAI Codex, in an era where “those who can delegate tasks to AI and verify the results to completion” grow faster than “those who are experts at coding.”
Non-majors and beginners with no coding experience
Instead of memorizing coding syntax, you will quickly create results and build your skills through a routine of "writing requirements → AI implementation → self-verification/modification."
Office workers who need task automation
You can reduce time and errors by fixing repetitive document, report, and web tasks into automated workflows using Codex.
PMs/Planners who lack coding skills but have many ideas
Even if you don't know how to write code, you can create a finished product all by yourself through Codex.
Development routines possible even for non-majors: Skills are built through a process of “writing requirements → AI building → me checking/improving” rather than difficult theories.
A sense of collaboration with AI: You will develop the instruction/feedback skills to break down tasks, set priorities, and more accurately derive the desired results with AI.
The power to complete to the end: You will gain the experience of completion, taking a project beyond a "demo" that stops halfway to a form that can actually be used or deployed.
Automation Mindset: You will learn the mindset of turning work into systems from the perspective of reducing repetitive tasks, rather than just "building it once and being done."
Create your portfolio website with Vibe Coding using Codex, and deploy it to the internet using GitHub Pages + Actions to master the "practical workflow from creation to deployment."
Implement it based on PRs in Codex Cloud and set it to run automatically every day using GitHub Actions' cron to get a feel for "systematizing repetitive tasks."
We will convert speech to text using the powerful Whisper AI model and add a web UI with FastAPI to complete your own practical, ready-to-use STT app.
By adding browser automation with the Playwright CLI Skill, you will learn the flow of "AI using tools like its own hands" while crawling web data.
You will learn how to build complex programs with Codex by collecting and organizing real-time funding fee data from various cryptocurrency exchanges and visualizing it on a dashboard.
Q1. Can I follow along even if I don't know how to code at all?
Yes, it is possible. This course is designed so that you don't have to write code yourself; instead, you learn through a workflow of "writing requirements in natural language prompts (Korean) → Codex implements → you check/modify."
Q2. Are there any prerequisites or required knowledge?
Basic PC skills (files/folders, installation, copy/paste) are all you need. I will quickly cover the essential tools and concepts during the lecture.
Who is this course right for?
Office workers who want to improve their work efficiency through "vibe coding"
Those who want to learn how to efficiently use OpenAI Codex for their work
Those who want to be the first to experience the future transformed by OpenAI Codex and Vibe Coding.
Need to know before starting?

It was great to learn not just how to use Codex, but how to apply it to an actual development workflow. The step-by-step explanations, covering everything from Git/GitHub basics to Codex App, Cloud, and CLI, made it easy to follow along. The hands-on projects—including a portfolio website, automated briefing, STT app, and dashboard—helped me understand specific ways to utilize the tool. It was helpful for learning the workflow of conveying requirements to AI and reviewing/modifying the results. The structure allowed even those without much coding experience to produce results by following the practice-oriented lessons. I would recommend this course to anyone looking to apply Codex to work automation or personal projects.

As someone just starting out in AI development, I found this course to be highly satisfying. In particular, the highlights were as follows: ■ A must-listen course for any AI development beginner - It explains everything step-by-step from the basics so that even those new to Codex can follow along. - It wasn't just an introduction to features; I was able to understand the actual development workflow. ■ Easy to understand thanks to the project-oriented approach - By implementing various examples myself, I naturally learned how to use Codex. - I was also able to experience modern AI development environments such as Playwright, FastAPI, CLI, and App Server. ■ High-quality examples - The examples are not just simple exercises, but ideas that can be developed into actual services. - While taking the course, I often thought, 'If I apply it this way, I could even monetize it.' ■ Significantly reduces trial and error - I looked through various educational sites, but it was hard to find a course that explains Codex as systematically as this one. - I think a big advantage is that you don't have to waste time looking for a good course. I believe this course will be helpful to everyone, from those new to AI coding to experienced developers. However, if I were to express a personal wish, I hope this isn't just a one-off course. I would love to see a follow-up advanced project-based course that goes one step further—focusing on developing actual AI services and connecting them to monetization. I confidently recommend this to anyone who wants to learn Codex properly.
