From No-Code Automation Basics to Practice: Mastering n8n (Directly Taught by Korea's First n8n Ambassador)

"You’re trying to do too much. Just try doing one thing."

That was feedback from my senior when I was a junior. Quite a bit of time has passed since then, but I still haven’t been able to follow that advice.

I want to analyze data, do 3D printing, create content, and build apps and web services.
And now I’m actually doing all of them. Of course, I can’t say I’m particularly good at any of them. But isn’t it enough if I’m having fun and feeling happy?

My senior was probably right back then. There simply wasn’t enough time to do everything alone. But after bringing AI into my work, the math changed. I can edit by telling it what to change, delegate repetitive tasks, and build a first version even without knowing how to code. Instead of cutting down on the things I want to do, it became possible to expand what one person can accomplish.

That said, there’s a gap between watching something in a video and trying it out directly in your own work. Most people get stuck when setting things up for the first time or turning an example into something of their own. I’m holding offline meetups so we can get through that moment together.

Waguwagu Club
It’s a meetup where people like me—people who want to do many things and don’t want to give up even one of them—come together to create.
We won’t tell you to choose and focus.

Starting October 19, we’ll meet every Monday through Thursday from 7 p.m. to 10 p.m. at FASTFIVE Gangnam 3, with one topic each day.

Monday: (Video Automation) Edit and upload videos you filmed but have been putting off, using your voice.
Tuesday: (Browser Use) An introduction to AI browsers—put an employee in your browser.
Wednesday: (Vibe Coding) Build the first version of an app you’ve wished existed through vibe coding / (Admin Night) A night to finally get through those postponed emails and documents together
Thursday: (OpenAI Dots, Muse.ai, GrokBot) Get started with AI assistants and entrust one small task to one

This is a good fit for people who:
- Have taken quite a few AI courses but still don’t have anything they’ve actually made for their own work
- Are job seekers who need work they can show, rather than simply saying, "I know how to use ChatGPT"
- Are employees or solo business owners who have kept putting off the things they want to do while handling everything from their main work to promotion and operations alone

Each session is limited to 10 people, so we’ll look at anything you’re stuck on together right there.
This isn’t a meetup where we promise to complete something amazing in three hours.
The goal is to finish one small result using your own material and leave with a process you can follow on your own next time.

Each session costs 100,000 won, and the first cohort is 90,000 won if you apply by October 18.
Wednesday’s Admin Night is free, and the 30,000-won deposit will be fully refunded when you attend.

If you’ve ever been told that you’re trying to do too much, you’ll probably fit right in.
If you’re not sure which day is right for you, feel free to ask.

There are some instructions regarding the lecture "Creating a YouTube Subtitle Summary Service".

It seems that YouTube has currently blocked the method of extracting subtitles without an API.

So, since the method provided in the current lecture is no longer valid, I will provide an alternative using the official YouTube method below.

Use the official YouTube API. (Free - but there is a daily quota limit. Quota means a set number of calls per day.)

• 250601_Youtube_Official_API_Subtitle_Extraction_Workflow

• 250601_Youtube_Official_API_Subtitle_Extraction_Guide

The official API is a bit complicated, so you may need to follow it step by step.

thank you

Data Popcorn Dream.

(Updated 2025-06-22) I uploaded a video on how to do it with Apify (API Marketplace Platform) on YouTube. If you have difficulty with the official API, watch this video and follow along!
