Creating Super Simple Group Chat for Non-Majors (Vibe Coding, Cursor AI)

👨‍👩‍👧‍👦 I made a private messenger for my child myself.

Have you ever thought about this?

“I’m worried about my young child using a commercial messenger…
For use only by family members,
“I wish there was a secure messenger!”

There are a lot of ads and you may connect with strangers.
Rather than a regular messenger
For use only by our family,
I wish there was a simple and secure messenger .

So using Flutter and Firebase
We created our own family-only messenger .
(This course uses Web + Firebase.)

iPhone, iPad, Android phone…
Because the devices used by each family member have different operating systems
I chose Flutter because it supports cross-platform .

🧑‍💻 But, how did you make this?

It's called 'vibe coding', which is very popular these days!

Because I have Apple and Google developer accounts
I even tried installing it on an actual device,

But in this lecture, you can do it without such an account.
So that anyone can easily follow along in a Windows environment
We have prepared a web-based messenger version.

First of all, it is important to try Vibe Coding!

📚 This lecture is for these people!

• Non-majors and beginners who think, "Is it okay if I don't know anything about development?"

• For those who want to start in an environment with only Windows, without a MacBook

• Anyone who wants to create a website that actually works with their own hands

• Anyone who wants to create their own messenger for use with family, couples, and friends

  
  

🎥 The lecture proceeds in this order

1. Completed Web Messenger Demo — Get inspired by the results first!

2. Creating Firebase, GitHub, and Vercel Accounts — Practical Preparation

3. Node.js installation and environment configuration — Step-by-step development environment setup

4. Install Cursor (AI Coding Assistant) — No worries, even if you're new to coding!

5. Start coding for real messengers — implement the features yourself.

6. Real-time web distribution via Vercel — My messenger, released to the world!

🌟 Your own web messenger that actually works

This course does not teach coding languages.
You just learn how to do vibe coding .

And the messenger created like this
You can actually use it with your friends and family.
You will complete the real messenger website .

🌱 And the next challenge is a Flutter app!
(We will not be creating a mobile app in this course)

If you have learned the structure and principles of messengers on the web,
Now you can try it yourself with the mobile app!

Flutter is a one-time code-write
An amazing tool that allows you to develop for iOS, Android, and the web simultaneously.
Someday you too
You can create your own app for your family .

It's okay even if it's your first time coding.
From the easiest starting line, we go together to the real thing.
Are you ready to create your own messenger? 😄
