How to Build a Simple AI App with Cursor in Under 2 Hours

Building an AI app sounds daunting, right? Especially if you’re a beginner. But what if I told you that you could get a basic AI app up and running in under two hours? In 2026, tools like Cursor have made it easier than ever to create simple applications without needing a PhD in machine learning. Let’s dive into how you can use Cursor to build a straightforward AI app, even if you’re just starting.

Prerequisites: What You Need Before You Start

Before we jump into the how-to, make sure you have the following:

1. Cursor Account: Sign up for a free account at Cursor.
2. Basic Coding Knowledge: Familiarity with JavaScript will help, but you can follow along if you’re willing to learn.
3. Node.js: Ensure you have Node.js installed on your computer. You can download it here.
4. A Code Editor: Use any code editor you prefer, like VSCode or Atom.

Step 1: Setting Up Your Environment

First things first, let’s set up our environment.

1. Open your terminal and create a new project directory:

   mkdir simple-ai-app
   cd simple-ai-app
   

2. Initialize a new Node.js project:

   npm init -y
   

3. Install the Cursor SDK:

   npm install cursor-sdk
   

Step 2: Building Your First AI Function

Now, let’s write some code to create a simple AI function. For this example, we’ll create an app that generates random jokes using Cursor’s built-in capabilities.

1. Create a new file called app.js in your project directory.

2. Add the following code to app.js:

   const Cursor = require('cursor-sdk');
   
   const cursor = new Cursor();
   
   async function getJoke() {
       const joke = await cursor.generate({
           prompt: "Tell me a joke",
           maxTokens: 30,
       });
       console.log(joke);
   }
   
   getJoke();
   

3. Save the file.

Step 3: Running Your AI App

Now that we’ve written our code, let’s run it!

1. In your terminal, run the following command:

   node app.js
   

2. You should see a random joke printed in your terminal. Congratulations! You’ve just built a simple AI app in under two hours.

Troubleshooting: Common Issues and Solutions

• Error: Module not found: If you encounter this error, ensure that you installed the Cursor SDK correctly.
• API Key Issues: If your API key is not working, double-check it in your Cursor dashboard.

What's Next: Expanding Your AI App

Once you’ve got your basic app running, consider adding features like:

• User Input: Allow users to request specific types of jokes.
• Web Interface: Use frameworks like Express.js to create a web interface.
• Deployment: Host your app using platforms like Heroku or Vercel.

Conclusion: Start Here

Building an AI app doesn’t have to be complicated. With Cursor, you can create something functional in just a couple of hours. Start by following the steps above, and don’t hesitate to experiment with your code. The best way to learn is by doing!
