This is a great course for getting started with vibe coding through Codex! It's a really easy and fun course because it clearly explains things that can be confusing at first, such as how to actually use it and how to set up the basic environment!!

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.

What you will gain after the course

  • 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

A new era where you can create software through conversations with AI, even if you know nothing about coding!

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.”

Recommended for these people

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.

After completing the course,

  • 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."

Features of this course

Project-based learning: This is not a lecture where you just listen to explanations; it is structured as "learning by doing," ensuring you have a tangible result at the end.

What you will learn

Create your own website and deploy it to the internet.

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."

Your very own financial report that arrives automatically every morning.

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."

Build a SaaS in just one hour—Create your own STT app with your own hands.

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.

Codex directly manipulates the browser to retrieve data.

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.

Seize opportunities with a real-time dashboard.

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.

        It was great to be able to gain an in-depth understanding of Codex, learn how to use prompts, and discover how to utilize subagents.
