The app development world is buzzing with a new term: “vibe coding.” It’s the idea of instructing an AI with plain English, like you’re chatting with a developer, and watching a functional app come to life. No complex syntax, no lines of code, just… vibes.
Honestly, I was skeptical. We’ve all seen “no-code” tools that promise the world but deliver a box. But then I started working at Crazzy, an open-source AI no-code tool for Flutter, and our tagline isn’t just a gimmick: “From Plain English to Playstore.”
I decided to put this to the test. Could I, using just a single prompt, build an app that wasn’t just a “Hello, World!” button? I chose a real-world idea: a home tutor marketplace app.
Here’s exactly how I did it.
What is Crazzy AI?
Before I show you the magic, let’s talk about the tool. Crazzy is an open-source AI development tool built specifically for Flutter. Unlike drag-and-drop builders that lock you into rigid templates, Crazzy is a conversational partner.
You give it a prompt, it generates the entire Flutter app. But the real power is in the chat. You can then say, “Change the color scheme,” “Add a login page,” or “Connect this button to Firebase,” and the AI refactors the code for you. It’s the “vibe coding” you’ve heard about, made real.
But Why Flutter?
This is a question we get a lot. Why not React Native? Why not Swift? We chose Flutter for a simple, powerful reason: performance and flexibility.
Flutter, Google’s UI toolkit, allows developers to build beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. This means:
- Stunning Performance: It compiles to native ARM code, so you get fluid animations and a 60fps (or 120fps) user experience.
- Pixel-Perfect Control: You get to control every pixel on the screen, ensuring your app looks and feels identical on both iOS and Android.
- Incredible Community: It has a massive, active open-source community, which aligns perfectly with our ethos at Crazzy.
By building on Flutter, Crazzy gives you a foundation of high-performance, cross-platform power. We just handle the coding part for you.
“Vibe Coding” the Home Tutor App
Okay, time for the test. I opened Crazzy, stared at the blank prompt box, and gave it my idea. I didn’t water it down. I gave it the full set of business logic.
This was my exact prompt:
“create an home tutor app where students post home tuition requirements and teacher apply teacher can browse the home tutor and apply and students can only post not apply and can see the teachers who apply on there requirement”
I hit enter and watched.
In under five minutes, Crazzy generated a complete, multi-screen Flutter application. Not just UI mockups, but functional code with a logical structure.
- It created two distinct user roles (Student and Teacher).
- It built a dashboard for Students with a form to “Post a Requirement” (e.g., “Need Math tutor for 10th grade”).
- It built a browseable list for Teachers to see all student requirements.
- It implemented the “Apply” functionality for Teachers.
- It created a “View Applicants” screen for Students, linked to their specific posts.
I was floored. The core logic was all there.

Student – test@student.com (test0123)
Refining the “Vibe”
This is where Crazzy truly shines. The first version was functional, but I wanted to polish it. I started “chatting” with the AI.
- Me: “Make the primary color a deep blue and add a ‘CrazzyTutor’ logo to the app bar.”
- Crazzy: Done. App updated.
- Me: “Add a new field in the student requirement post for ‘Location’.”
- Crazzy: Done. Database schema and UI form updated.
- Me: “Ensure teachers have to create a profile with their ‘Subjects Taught’ before they can apply.”
- Crazzy: Done. Added a teacher profile creation flow and locked the ‘Apply’ button until the profile is complete.
Every prompt refined the app, and Crazzy handled the code generation, state management, and even the folder structure.
From Plain English to a Real App
The no-code and low-code market is exploding, but Crazzy feels like the next step. It’s not about limiting what you can do; it’s about accelerating your ideas.
In less than an hour, I had an app that was 90% ready. A traditional developer would spend days, even weeks, setting up the basic architecture for these features. I did it with plain English, all built on the powerful foundation of Flutter.
This is the power of “vibe coding.” You bring the vision; Crazzy brings the code. And just like that, you’re one step closer to the Google Play Store.
