This is a hands-on OpenAI Codex course for both non-developers and developers. You’ll learn everything from the basics to building websites and programs, automating tasks, harness engineering, and advanced features with ease, while developing the ability to learn new features independently using the latest official documentation.

I got answers from AI, but am I still doing the work myself? From the basics of using Claude Code to building apps, automating Instagram carousel posts, and researching competitors’ social media. Follow along while watching the screen and learn how to apply it to your own work. This includes 11 beginner-focused desktop app lessons, along with hands-on practice for real-world tasks.

AI writes on Slack and Notion for me? Work smarter with MCP, which goes beyond the limits of existing AI!

Are you just telling Claude Code, “Build it for me”? It works well at first. But as the project grows, the AI modifies the wrong files, forgets the rules, and repeats the same mistakes. In this course, you’ll learn how to leverage **the latest Claude Code** to delegate coding while still keeping the developer in control of **design, permissions, context, and verification**. **Design → Plan → Implement → Test → GitHub PR** Based on the developer’s judgment and review, AI-powered development automation is applied throughout this entire process.

From AWS EC2 backend operations to automatic error fixing, we are revealing the entire development process of Sidabari (https://github.com/cx8537/sidabari), a Claude Code-based automation tool. In this course, we provide all the actual prompts and conversation history used as learning materials, allowing you to experience the entire prompt input process involved in its creation.

We invite you to the fascinating world of coding where you analyze and visualize financial statements using only prompts. Without a single line of code, you create and deploy a service in consultation with AI.

Are you losing time to these recurring weekly tasks—organizing meeting minutes, writing reports, and compiling materials? This course does not simply list how to use Gemini. Instead, you will work through the practical task of “introducing a new AI tool to our team” from start to finish: researching with Deep Research → understanding with NotebookLM → sharing with Canvas → managing with Sheets → automating with Workspace Studio → and turning decision-making criteria into reusable assets with Gems. This is not a lecture; it is a workshop. You need to pause the videos and follow along hands-on. By the end, you will have learned more than how to use these tools—you will have developed a new way of working in which AI creates the drafts and you make the decisions.

We introduce basic prompt patterns for coding and advanced API prompt patterns for leveraging artificial intelligence.

This course is a practice-oriented lecture that goes beyond 👉 just explaining the concepts of RAG (Retrieval-Augmented Generation), 👉 to building the actual working architecture yourself, 👉 and experiencing expansion and optimization. Starting from simple RAG examples, you will learn step-by-step—from Advanced RAG to Modular RAG and Agent-based RAG—at a level that can be immediately applied in the field.

Can you make a proposal look convincing with AI, but lack the confidence to bring it into the meeting room? A global content strategist with 17 years of experience—who built practical planning expertise at major advertising agencies and global e-commerce companies, and had that expertise validated on a global education platform—will teach you the principles of planning that work in practice and AI workflows, from defining the problem to completing the slides.

This is a hands-on career and college admission project course where high school students use the AI-SPARS system to analyze their academic records, mock exam scores, and student record activities to explore their desired majors and universities. Students will compare various admission types, such as early and regular admissions, and personally design grade-specific roadmaps and execution strategies to reach their target universities. It is a practical course where high school students utilize AI-SPARS to analyze their grades and student record information while exploring desired majors, universities, departments, and college admission tracks. Participants will directly install and use the AI-SPARS program to create their own college admission profile and complete a strategic admission plan and roadmap to reach their target universities.

There may be people who have never taken my lecture, but no one has taken it only once. After teaching in person for so long, I have finally had the opportunity to create this online course. Since the commercialization of AI, I have produced and researched countless pieces of AI content. Based on that knowledge and experience, I have built a logical philosophy of my own and organized it into concepts that are easy for anyone to understand. For those who have been generating AI images without considering the underlying concepts, I will instill a proper foundation in you. Once you take this course, you will be able to create any AI image in the future. Have you never created an AI image before? That’s perfectly fine. You don't need any prior experience in AI image generation. By simply learning and practicing through this lecture, you can become an expert in AI content creation.

"Will you make money just by building an app? No." Vibe Coding is merely a tool; the core is 'profitable planning and strategy.' This course goes beyond simple Vibe Coding technical training to reveal a practical manual for building a revenue automation system, learned firsthand by a non-developer operating 200 apps.

Just say it, and AI will do it! From files and reports to emails. The Claude Cowork practical course for full automation without coding!
