I created an “all-in-one video editor” that lets you plan, create, and see the results yourself.

Basic usage of Claude Code is now easy to come by. However, it's rare to get a chance to see how an expert actually uses it in practice. Kang Hyeop, author of the bestseller "AI Gap," will show you everything from his workspace setup to his workflow, demonstrating exactly how he utilizes it on screen.

It's okay if AI feels unfamiliar and difficult to you. In just one week, I will share the entire "trial and error" journey of building everything from a membership landing page to automation and data analysis from scratch using Claude Code. Even if you don't know how to code or are a complete AI beginner, I'll show you through real-world examples so you can take on the challenge yourself.

Hundreds of saved materials, but zero materials opened again. Materials that are just piled up and never looked at. Are you perhaps doing the same? We're sharing a case study of someone who built their own OS to solve this problem.

Embed your tone, keywords, and structure into a Claude Project to build a workflow within Claude chat, covering everything from research to drafting.

You want to create a brand, but you're not sure where to start, right? From zero—with no brand and no product—we will define the value and complete the product detail page together with Claude. We will demonstrate the entire process in one place.

There's so much talk about AX these days. At Selfish Club, we started asking ourselves, "How 'agentic' can our way of working actually become?" So, for two months, we just dove right in. From how we drew the roadmap and what our non-developer crew members built with Claude, to how we transformed the process of creating product detail pages—which we used to build from scratch every time—into a system. Instead of a polished conclusion, we're sharing the raw, chaotic process of our trial and error.

There are so many stories saying, "Automation is just one click away." However, it's easy to give up when you actually try to apply it to your own work. We have captured the raw record of a team that spent six weeks narrowing the gap between "it works" and "I am using this for my work!"

I will show you "where to start" through a case study of building a service with non-developers in just one day, and explain "how to manage and collaborate" using the example of designing the GitHub structure for the Selfish Membership team.

Four creators who have actually conducted AI video projects in various industries such as athleisure and beauty will reveal how to create "AI videos used in real business." We will show you actual use cases and workflows, not just possibilities.

This sharing session was prepared not for those who are already proficient in Claude, but for those who are just starting out and feel overwhelmed by where to begin. We will show you the entire process of a real-world project—from planning and CRM automation to content creation and ad analysis—all handled in one-stop within a single conversation, using actual cases.

We are revealing the entire process—without filters—of how non-developers built a Slack bot from scratch, including all the trial and error along the way.

We are truly in an era where anyone can create their own service in just a single day. In the previous Vibe Coding workshop, the goal was to experience firsthand what Vibe Coding is all about, and for everyone to complete and deploy the frontend (the visible pages) of the service they wanted to build. This upcoming workshop goes beyond simply creating a service that looks good. It focuses on a development approach that emphasizes imagining specific actual users and asking, "Who will use this service, and why?" Through the workshop, participants will learn how to clearly define their target users and the problems they aim to solve while building their own services. It’s perfectly fine if you’re new to Vibe Coding! You don't need to know how to code or understand development. Experience more than just following along—come and create a truly functional service yourself at this workshop!

In this sharing session, the members of NDA AI Studio, the AI video team of Selfish Club, will personally share their experience! Based on an actual project conducted with the senior dog supplement brand Dr. Ian, we will share how we designed and executed the entire brand marketing process using AI. From creating an animated universe that captures the brand philosophy to planning and executing product detail pages and producing short-form videos for conversion! We plan to share the actual workflow, focusing on which AI tools were used for what purpose at each stage and how multiple tools were combined. For those who knew there were many AI tools but wondered how they are used in real projects, or those who felt overwhelmed by tool combinations and practical workflows, please take this opportunity to see for yourself which tools were combined and how the actual flow works. We will share everything from the trial and error to the know-how experienced by the NDA AI Studio team, all based on real-life cases.

For brand operators who find it difficult to respond to the daily flood of reviews, If you've ever thought, "Do I really have to read all of these?", This sharing session will be helpful. Review content also needs a brand universe. We will share strategies for constructing consistent response content using your brand's unique language. Review management is marketing that creates fans. Now, turn reviews into opportunities with your own brand universe.

There are so many stories saying, "Automation is just one click away." However, it's easy to give up when you actually try to apply it to your own work. We have captured the raw record of a team that spent six weeks narrowing the gap between "it works" and "I am using this for my work!"

Do the results of vibe coding keep turning out differently from what you intended? Learn a workflow that uses specification-driven development (SDD) and Spec Kit to define goals, scope, business rules, and completion criteria, then shares the same specifications with Claude Code and Codex to reduce repetitive revisions.

Are you using AI but still typing new prompts every single time? Code is being generated, but are team-level automation and systematization still out of reach? This course is not about learning Claude Code as a "conversation tool." It is a course where you will learn how to design AI as a system using Agents, Sub-agents, Agent Teams, Memory, and Hooks.

This is an 18-lesson course across 5 modules designed to transform Generative AI LLM agents—which often drain money through API costs—into a profitable structure by controlling expenses with model routing, cascading, caching, and loop guardrails. You will personally build everything from analyzing real-world cases of "cost bombs" to profit-and-loss simulations and architecture design projects. We recommend this course to AI developers and makers burdened by API costs, as well as those planning or operating agent-based services.

If you design the tests first, AI handles the implementation. A practical development approach that captures both speed and quality!

Stop asking developers every time! Create websites and various services without using expensive outsourcing!

[Let's Build!] Have you ever given up because you were tired of connecting nodes? "Create a daily morning briefing on Slack" — that's all it takes. Claude Code designs it, and the n8n server runs it 24/7 for you. [Let's Operate!] If adopting n8n was easy but managing it felt overwhelming, this lecture is the answer. "Organize everything according to the conventions" — dozens of workflows are tidied up at once. Creation, organization, monitoring, and backup—operate everything using natural language.

From PC and mobile web development to AdSense and service operations. Understand how the web works and bring your ideas to life as responsive websites with AI. Go beyond creation and deployment by practicing search registration, AdSense applications, and data-driven improvements, while preparing for your first business with login, databases, and test payments. This is a hands-on course for trying monetization; AdSense approval or revenue is not guaranteed.

If you don’t know why things keep breaking when you have AI do it, the problem isn’t coding—it’s telling it what to do without understanding “what’s happening.” I’ll teach you vibe coding by taking a web service with login and payments from scratch all the way to launching it on your own domain and getting it indexed by search engines, while understanding the context behind “What just happened?” at every step.
