Most people using AI tools are completely overlooking a certain "way to earn money."
That is "Vibe Coding."
It is a method of creating apps by delegating development entirely to AI without writing a single line of code.
This term was proposed by Andrej Karpathy, a co-founder of OpenAI.
In February 2025, he named this development style—where you "forget the existence of code and just talk to the AI"—as Vibe Coding.
And indeed, people have already emerged who are earning money using this method.
"I don't understand programming even one millimeter."
So says George, an 18-year-old college student who uses AI to earn 3.3 million yen per month.
He launched an app in just one month without writing a single line of code.
From there, he exceeded 3 million yen per month in less than half a year.
This difference is not "talent."
Even though they use the same AI, the "depth" of how they use it is simply different.
What is Vibe Coding in the first place?
Vibe Coding is a development method where you complete apps or services just by giving instructions to AI in natural language.
The premise is completely different from traditional programming.
❌ Traditional: Learn a language, write code, and fix errors yourself.
✅ Vibe Coding: Tell the AI what you want to do and run what comes out.
George's development flow is as follows:
- Delegate code entirely to AI (mobile-specific tools + ChatGPT).
- If an error occurs, paste the log directly into the AI to fix it.
- Outsource only the payment function, which is difficult to do alone, for $250 (about 37,000 yen).
In other words, all he did himself was "instruct" and "copy-paste."
As a result, development that previously took a year and a half was shortened to just one month.
Why "One Launch per Month" is the Strongest Strategy
The core of George's success is not technology.
It's the "number of times at bat."
Once he was convinced that "apps can be made with AI," he continued to release new works at a pace of one per month.
He targeted niche demands, such as the martial arts app "Fight AI," which utilized his own wrestling experience.
Why does this strategy work? There are three reasons.
Reason 1: Hits are a matter of probability
No one knows which app will be a hit until it's released.
There are about 1.8 million apps in the App Store (according to Statista, 2024).
Conversely, the idea of trying to hit it big with just one app is a mistake.
Reason 2: Development costs are almost zero
Since you can delegate everything to AI, the cost of making one app is only time.
Outsourcing costs that used to range from hundreds of thousands to millions of yen have almost disappeared.
That's why "releasing in volume on the premise of failure" works.
Reason 3: Learning accumulates with each app
If you release 10 apps, you get user feedback for 10 apps.
This high-speed trial and error dramatically increases the probability of the next hit.
A "Year and a Half Failure" at Age 15 was the Driving Force
George didn't start out moving smartly.
At age 15, he poured all his savings into outsourcing app development.
However, it took a year and a half to complete.
By the time it launched, his passion had cooled, and the social media momentum had vanished.
The lesson he learned here is clear:
"Spending too much time on outsourcing or learning programming is a risk in itself."
Because of this failure, he was able to make the decision to go all-in on AI.
5 Mindsets to Avoid
Working backward from George's case, we can see the actions to avoid.
❌ Mistake 1: Thinking "after I learn programming."
✅ AI writes it, so learning is unnecessary.
❌ Mistake 2: Trying to finish the first app perfectly.
✅ The correct answer is to release "something that works for now."
❌ Mistake 3: Overthinking hit ideas.
✅ Release rather than think. Hits are determined by probability.
❌ Mistake 4: Betting all resources on one app.
✅ Disperse the numbers and increase your turns at bat.
❌ Mistake 5: Thinking failure is a shame.
✅ The cost of failure for one app is now close to zero.
3 Terms Often Confused
Let's organize the terminology here.
- "Programming" = The act of humans writing code using a language.
- "No-code" = Development that doesn't require code, made by combining parts.
- "Vibe Coding" = A method where you instruct AI with words, and the AI generates the code.
What George did was the third one.
What you can start today is also the third one.
Summary: What to do today
For those who feel "doing everything is a hassle."
I will organize the priorities with the time required.
Top Priority (5 minutes): Touch one AI tool
Even ChatGPT is fine; try typing "I want to make an app."
Next to do (+7 minutes): Write down one app idea you want to make
Niche is fine. One line from your hobbies or experience is enough.
If you have time (+3 minutes): Throw that idea to the AI and see the reaction
If you think "it might work," you're already halfway successful.
The difference between the top 5% and the 95% is not talent, but "whether you released one for now."
Out of about 1.8 million apps in the App Store, only those who stood at bat will hit the mark.
Now that development costs are approaching zero, the benefit of not moving is almost zero.
There is no reason why an 18-year-old boy can do it and you can't.
Start by copy-pasting "I want to make an app" to an AI.
That is the first switch to 3 million yen a month.
Finally, just one thing
However.
"Developing an app suddenly is a high hurdle."
"I feel like I'm going to stumble just connecting tools or setting them up."
Many of you must have felt that way.
I understand that feeling very well.
That's why there is a first step I want to recommend.
First, "make a slide" with ChatGPT.
That's it.
It's much easier than an app.
No connections or complicated settings are needed.
Just by typing in a theme, it takes shape.
The experience of "Did I make this myself?"
What's important is a small success experience.
"I used AI, and this is what I got."
Get this feeling first.
Actually, this slide.
All of it was made by AI.
There isn't a single page made by hand anymore.
If you could make a slide of the same quality.
Honestly, don't you think it's a bit like a dream?
No difficult talk is needed at all.
Type in a theme. The AI spits it out. You look at it and are surprised.
This is the order.
The content of the GPTs being distributed
What I'm giving you this time is a ChatGPT GPTs.
It's a finished product pushed to the limit in just one area: "slide creation."
I guarantee it.
All you do is type in the theme.
After that, the thoroughly designed GPTs will spit out the slide without hesitation.
The article that first introduced this GPTs recorded 400,000 impressions.
https://x.com/masaki_aihack/status/2068646555524223366
It means 400,000 people reacted, thinking "this is different."
How to receive
And for a limited time only.
I am distributing a total of "20 benefits," including this GPTs.
How to receive is simple.
Enter the LINE Open Chat below. That's it.
I'll be honest.
This GPTs was not completed in one go.
I failed more than 50 times.
It took a week to finally get it to the point where "anyone can use it."
I will distribute that manual as it is this time.
Let me say it just one more time.
Before bracing yourself for an app, first taste the "I did it" with a slide.
That is the first step to earning with AI.
Those who start moving and those who just watch. Which one will you be today?
Register for the LINE Open Chat before you forget.
