If you’ve started vibe coding but keep coming to a stop
They say AI does everything, so
why am I the only one who keeps getting stuck?
I came to realize this while teaching beginners how to vibe code.
What was invariably missing for those who got stuck was
exactly 7 basic concepts.

Wait, have you ever experienced this?
AI says, “I fixed everything,” but
why does the screen still look the same?
It was supposed to be “easy and fast,” but there’s a reason
only my screen keeps freezing.

⚠️
This page isn’t working
At my-app.vercel.app,
an error occurred.
Application error · HTTP 500
When you ask it to fix the issue, it says again, “It’s fixed.”
Because you don’t know why it isn’t working, this cycle never ends.
If even one of these sounds like you,
please read to the end.
01
“I fixed it, so why am I getting the same error again?”
Since you don’t know what needs fixing, you keep asking the AI again and again… Since you don’t know the cause, three hours simply disappear.
02
“I don’t know why this turned out this way either.”
Even when it doesn’t turn out the way you wanted, you can’t ask back, “Why did you do it this way?” Since you don’t know what’s right, you just accept whatever the AI gives you.
03
“Only half-finished folders keep piling up.”
It’s always exciting to start, but I’ve never seen anything through to the end. Everyone else seems to be creating and posting things, but the feeling that I’m the only one stuck in place is the hardest part.
First of all, let me say that
It wasn't a matter of talent or intelligence, either.
The problem isn’t AI; it’s that you
don’t have the “basics” to guide AI.
The first question this VOD answers
AI writes everything for me, so
why do I need to know the basic concepts?
It’s not to write the code yourself.
It’s to give AI proper instructions and evaluate the results.
When you lack the basics
“An error occurred”
“It still doesn’t work”
“Please try again”
Because you can’t say what went wrong, the AI also guesses and makes fixes. So you keep going around in circles.
→
When you have the basics in place
“It seems like a server-side error.”
“Check this file first.”
“Roll it back to the previous version.”
Since it can pinpoint where the problem is, the AI fixes it accurately in one go.
Not the skill of writing prompts well, but
knowing what to ask for.
This was the difference between those who get stuck and those who create.
The second question this VOD answers
So, what should I
learn first?
Development knowledge is vast, but you don’t need to learn it all.
We narrowed it down to only what beginners need to make it to the end of the points where they actually get stuck.
Just 7 things.
1
터미널
The first gateway to giving commands to a computer.
If you don’t know it → the moment AI says, “Enter this,” your hands freeze.
2
웹 동작 원리
HTML · CSS · JS
The structure in which the screen is rendered.
If you don’t know it → you won’t be able to pinpoint what needs fixing.
3
버전 관리
Git
A safeguard that makes it possible to roll back.
If you don’t know it → even if AI completely rewrites code that was working well, you have no way to restore it.
4
프레임워크
Next.js
The backbone of a properly built service.
If you don’t know it → you won’t understand why the files are structured this way, making it impossible to review AI-generated work.
5
데이터베이스
A place to store and retrieve data.
If you don't know → you won't even understand why everything disappears when you refresh.
6
인증 · 인가
Login and permissions, how to protect my data.
If you don't know → you may add a login, only to have other people's information exposed.
7
배포
The final step: make it public and turn it into a real service.
If you don’t know how, → it will remain a result that runs only on your computer forever.

These are the ones causing the most trouble right now
In the video, we’ll briefly go over what each of these 7 things is and why they’re needed.
We won’t go into depth, nor will we make you memorize terminology.
This is time to draw a map first, starting from day zero of coding.
Zero Entry Barrier
Rather,
those who know nothing should watch this.
This time isn't necessary for those who already know this well.
It is explained for those who are complete beginners.
✓
Even if you don't know what HTML·CSS are
✓
Even if you've never opened a terminal before
✓
Even if it’s your very first day of coding
It's okay.
It's a video made for people like you.
Why you can trust these 7 things
Those who learned it first
say the same thing.
These are reviews of the official course that covers all seven of these points exactly as presented.

“Vibe coding seemed easy, yet I felt at a loss about how to get started. Through this course, I feel I’ve found my direction.”
“Every lecture was packed with valuable and engaging content, so I stayed immersed and completed the entire course. I was especially impressed by the quality of the handbook!”
“Rather than simply listing how to use tools, it clearly pinpoints the ‘core concepts’ that remain unchanged when collaborating with AI.”
“I’ve taken several courses, but this is the first one I completed so quickly. It was practical enough to apply right away.”

“Just the essential web fundamentals you need to control AI, served up in bite-sized pieces. It gave me a clear sense of direction when I had felt lost.”
“It was a course that even beginners could easily follow and that helped them get a feel for ‘what vibe coding is all about.’”
“As a non-developer, I now clearly understand version control, authentication, and deployment—things I couldn’t understand on my own. This is the most practical course.”

We understand why you're hesitant too.
The Most Frequently Asked Questions Before Watching
Q.
Do I really not need to know anything? I’m a complete beginner.
A.
We designed it with that in mind. We explain things clearly enough for someone who has never opened a terminal to reach the point of understanding, “Ah, so that’s why this is needed.” We don’t make you memorize terminology.
Q.
In an age when AI does everything, do I really need to learn even the basics?
A.
Not to write code yourself, but
to give AI proper instructions and review the results
you need the basics. Without a foundation, you won’t even know what AI got wrong, so the moment a problem
arises, you’ll be stuck there.
Q.
Doesn't it take a long time to learn from the basics? I want to build something quickly.
A.
It’s not about mastering all seven things.
Even just knowing what’s out there changes the way you communicate with AI. It’s much faster to look at the map first than to spend a day fumbling around without knowing which direction to take.
Q.
I’ve already tried some vibe coding. Does this apply to me too?
A.
If anything, it may resonate more deeply with those who have gotten stuck at least once.
It is only then that "why I got stuck back then" finally has a name.
Please remember just one thing.
AI is getting faster even at this very moment.
For those with the basics, that is an
accelerator,
but for those without the basics,
it is a
widening gap.
If you put it off, you'll be stuck in the same place tomorrow too.
Just one episode is enough to set you on the right path.
