How to Use Cursor to Write Your First AI-Powered App in Under 2 Hours

If you’re like me, the idea of building an AI-powered app can feel daunting. With so many tools and frameworks out there, it's easy to get lost in the noise. But what if I told you that you could create your first AI app in under two hours using Cursor? Yes, you read that right. Cursor has streamlined the building process, making it accessible even for those of us who aren’t full-time developers. In this guide, I’ll walk you through the steps, share what you need, and highlight some honest trade-offs along the way.

Prerequisites: What You Need Before You Start

Before diving in, make sure you have the following:

1. Cursor Account: Sign up for a free account at Cursor.
2. Basic Understanding of JavaScript: You don’t need to be an expert, but familiarity with the basics will help.
3. Node.js Installed: Ensure you have Node.js installed on your machine (version 14 or later).
4. A Code Editor: I recommend using Visual Studio Code, but any editor will do.

Step-by-Step Guide to Building Your App

Step 1: Set Up Your Project

1. Open Cursor and create a new project.

2. Choose the "AI App" template. This comes preloaded with essential components.

3. In the terminal, run:

   npm install
   

   This command installs necessary dependencies.

Step 2: Integrate AI Features

1. Locate the ai.js file in your project folder. This is where you’ll define your AI functionalities.

2. Replace the placeholder code with the following snippet:

   const AI = require('cursor-ai');
   
   const response = AI.generateResponse("What topic do you want to discuss?");
   console.log(response);
   

3. Save your changes.

Step 3: Testing Your App

1. In the terminal, start your app by running:

   npm start
   

2. If everything is set up correctly, you should see your AI response in the console.

Expected Outputs

After running your app, you should see something like:

AI Response: "Let's talk about AI!"

Troubleshooting: What Could Go Wrong?

1. Error in Installation: If you encounter issues during npm install, ensure your Node.js version is compatible.
2. No AI Response: Double-check your API key and make sure it’s correctly set up in your config.js file.

What We Actually Use

In our experience, we’ve found that the Pro plan is worth it if you’re serious about building multiple projects. The free tier is great for testing the waters, but you’ll soon hit limitations that could stall your progress.
