A few years ago, if you wanted to build an app, you had two options: learn to code for months, or pay a developer thousands of dollars. Today, there's a third option. You just describe what you want, in plain English, and AI builds it for you. It's called vibe coding, and it's changing who gets to build software.
Hey, I'm Adam, and welcome to Build and Earn AI. In this video, you'll learn exactly what vibe coding is, which tools to use, how to write prompts that actually work, and the risks nobody talks about. So, what is vibe coding? The term was made popular in early 2025 by the AI researcher Andrej Karpathy.
The idea is simple: instead of writing code line by line, you talk to an AI and let it write the code for you. Here's the loop. First, you describe what you want. Second, the AI writes the code. Third, you test the result. And fourth, you tell the AI what's wrong, and it fixes it.
Then you repeat. With traditional coding, you need to know the syntax. With vibe coding, you need to know what you want, and how to explain it clearly. Now, there are two main types of vibe coding tools, and picking the right one matters. The first type is app builders, like Lovable, Bolt, Replit, and Hostinger's new AI Builder.
You type a prompt in your browser, and you get a working app or website, often with hosting included. These are the best place for beginners to start. The second type is AI coding assistants, like Cursor or Claude Code. They work inside real code projects, and they're much more powerful, but they're made for people who already understand some code.
My advice: start with an app builder. When you hit its limits, that's when you graduate to a coding assistant. Let me show you what this looks like with a simple example: a habit tracker. Prompt one: build a simple habit tracker where I can add habits, and check them off every day. In about a minute, you have a working first version.
Prompt two: add a weekly progress chart, and make the design purple and modern. The AI updates the app. Then you notice a bug: checked habits disappear when you refresh the page. So you simply tell it: my checked habits disappear after I refresh, please save them. And it fixes it. Prompt four: add a login, so every user has their own habits.
And finally, you publish it, and you get a real link you can share. Now, the quality of your app depends almost entirely on your prompts. Here are five rules that make a huge difference. Rule one: be specific. Say who the app is for, what it does, and what the main screen should look like.
Rule two: build one feature at a time. If you ask for ten things in one prompt, you'll get ten half-working things. Rule three: when something breaks, describe exactly what you see, and paste the error message if there is one. Rule four: save working versions. Most tools let you go back, so do it before every big change.
And rule five: ask the AI to explain what it did. That's how you slowly learn, without ever opening a coding course. But vibe coding isn't magic, and there are real risks. First, security. AI-generated apps can have security holes, so be very careful before you store real customer data or take payments. At the very least, ask the AI to review the app for security issues, and use the tool's built-in login and payment features.
Second, cost. Most tools work with credits, and long back-and-forth conversations can burn through them fast. Clear prompts save you money. And third, bigger apps get messy. Vibe coding is amazing for prototypes, small tools and simple websites, but complex software still needs real engineering. So, what can you actually build and earn with? Tiny tools for a specific group of people, websites for local businesses, internal tools that save a company time, or a prototype you can show to investors or clients.
I covered five ways to turn these skills into income in my last video, so check that out after this one. In my next video, I'll show you how to build a real SaaS app with no code, using Hostinger's AI Builder in agentic mode, step by step.
