Mastering AI Coding: How to Build a Simple App in Just 2 Hours

In 2026, the landscape of coding has drastically changed thanks to AI tools that simplify and streamline the development process. As indie hackers and solo founders, we often find ourselves juggling multiple roles, and the idea of building an app can seem daunting. The good news? You can create a simple app in just two hours using AI coding tools. Let’s dive into how to do this effectively.

Prerequisites: What You Need Before You Start

Before you jump into building your app, make sure you have the following:

1. A computer: Preferably with a decent processor.
2. An internet connection: To access AI tools and resources.
3. Basic coding knowledge: Familiarity with JavaScript or Python will help, but is not strictly necessary.
4. Accounts on AI coding platforms: Sign up for tools like GitHub Copilot, Replit, or ChatGPT.

Step 1: Choose Your AI Coding Tool

Here are some popular AI coding tools to consider for your app development:

| Tool | What It Does | Pricing | Best For | Limitations | Our Take | |--------------------|------------------------------------------------|-----------------------------|------------------------------|-------------------------------------|----------------------------------| | GitHub Copilot | AI-powered code suggestions for various languages | $10/mo per user | Developers looking for assistance | Limited to supported languages | We use this for quick code snippets. | | Replit | Collaborative coding environment with AI assistance | Free tier + $20/mo pro | Real-time collaboration | Performance can lag with large projects | We love its community features. | | ChatGPT | AI chatbot that can generate code snippets | Free tier + $20/mo pro | Quick coding help | Context can sometimes be lost | Great for brainstorming ideas. | | Tabnine | AI code completion tool for multiple languages | Free tier + $12/mo pro | Developers seeking efficiency | May not understand complex logic | Good for enhancing productivity. | | Codeium | AI-powered coding assistant with debugging help | Free | Beginners and pros alike | Limited integrations | We find it useful for debugging. | | Ponic | AI tool for generating full-stack applications | $29/mo, no free tier | Full app generation | May need manual tweaking | We use it for rapid prototyping. | | Koding | Cloud-based IDE with AI assistance | Free tier + $25/mo pro | Remote development | Can be slow on older machines | Ideal for team projects. | | AI Dungeon | Interactive storytelling and coding tool | Free + $10/mo for premium | Fun coding experiments | Not designed for serious projects | Fun way to learn coding concepts. |

Step 2: Define Your App Idea

In our experience, keeping it simple is key. For this tutorial, let’s build a basic to-do list app. The features will include:

• Adding tasks
• Marking tasks as done
• Deleting tasks

Step 3: Use the AI Tool to Generate Code

Example with GitHub Copilot:

1. Open your code editor and create a new file called todo.js.
2. Begin typing prompts like “Create a function to add a task” and watch Copilot suggest code.
3. Implement the suggestions, tweaking as necessary.

Expected Output:

After following the prompts, you should have a file with basic functions for adding, marking, and deleting tasks.

Step 4: Testing Your App

Run your code in the terminal. You should be able to interact with your to-do list app. If you encounter errors, here’s how to troubleshoot:

Common Issues and Solutions:

• Error: Task not added: Check that your add function is correctly linked to the UI.
• Error: Task not deleted: Ensure your delete function is targeting the correct task.

What's Next?

Once your simple app is up and running, consider enhancing it with additional features like saving tasks to local storage or allowing user authentication. This is a great way to build on what you’ve learned and expand your skills.

Conclusion: Start Here

Building a simple app in just two hours is entirely feasible with the right AI coding tools. Start with a clear idea, choose an AI tool that fits your needs, and follow the steps outlined above.

What We Actually Use

For quick projects, we often rely on GitHub Copilot for coding suggestions and Replit for collaborative coding. These tools have saved us countless hours and helped us ship products faster.
