How to Use AI Coding Tools to Build Your First Simple App in 2 Hours

Building your first app can feel like an insurmountable task, especially if you’re not a seasoned developer. But what if I told you that with the right AI coding tools, you could build a simple app in just two hours? In 2026, this is not only possible but also practical. Let’s dive into how you can leverage these tools effectively.

Prerequisites: What You Need Before You Start

Before we jump into the tools, here’s what you’ll need to have on hand:

• A computer with an internet connection
• Basic understanding of programming concepts (variables, functions, etc.)
• An idea for a simple app (e.g., a to-do list app or a weather checker)

Expected Outputs

By the end of this tutorial, you’ll have a functioning simple app that you can run locally or deploy to a platform like Heroku or Vercel.

Step-by-Step Guide to Building Your App

Step 1: Choose Your AI Coding Tool

Here's a list of AI coding tools to consider:

| Tool Name | What It Does | Pricing | Best For | Limitations | Our Take | |------------------|-------------------------------------------------------|-----------------------------|--------------------------------|--------------------------------------------|-------------------------------------| | GitHub Copilot | AI-powered code suggestions directly in your IDE | $10/mo for individual users | Quick coding assistance | Requires IDE integration | We use it for rapid prototyping. | | Replit | Online IDE with built-in AI suggestions | Free tier + $20/mo pro | Collaborative coding | Limited to web-based applications | Great for team projects. | | Tabnine | AI code completion tool that supports multiple languages | Free + $12/mo for pro | General coding assistance | Performance can slow down with large files | We find it helpful for JavaScript. | | Codeium | Free AI coding assistant for various programming languages | Free | Beginners and students | Lacks advanced features compared to others | We appreciate the no-cost option. | | ChatGPT | General AI that can generate code snippets and explanations | Free tier + $20/mo for pro | Learning and debugging | Not specialized for coding | We consult it for learning. | | Sourcery | AI that improves your code quality and suggests changes | Free + $12/mo for pro | Refactoring code | Limited language support | We use it for Python projects. | | Ponicode | AI tool for writing unit tests | $15/mo | Test-driven development | Can be complex for beginners | We don’t use it as much. | | DeepCode | AI that reviews your code for bugs | Free + $20/mo for pro | Code quality assurance | Limited to certain languages | Useful for code reviews. | | Codex | Powers various coding applications, including GitHub Copilot | Based on usage | Advanced coding tasks | Can be expensive for heavy usage | We use it for complex tasks. | | BuilderAI | No-code platform powered by AI | Free tier + $50/mo pro | Non-developers | Limited customization for developers | We recommend it for non-coders. | | Glitch | Collaborative coding platform with real-time editing | Free | Quick prototypes | Limited performance for larger apps | Ideal for quick builds. |

Step 2: Set Up Your Development Environment

1. Choose an IDE: If you’re using GitHub Copilot, set up VSCode. For Replit, just create an account and start a new project.
2. Install Necessary Extensions: For VSCode, install the GitHub Copilot extension.
3. Create a New Project: Depending on your tool, start a new project or workspace.

Step 3: Write Your Code

Using the AI tool, start coding your app. For example, if you’re building a simple to-do list app, you might begin with:

// Simple To-Do List App
const todos = [];

function addTodo(todo) {
    todos.push(todo);
}

function showTodos() {
    console.log(todos);
}

Use your AI tool to help generate more functions or optimize the existing ones.

Step 4: Test Your App

Run your code directly in your IDE or through a terminal. Check for errors and use your AI tool for debugging help.

Step 5: Deploy Your App

Once everything looks good, deploy your app. If you’re using Replit, it has a built-in deployment option. For other tools, consider platforms like Heroku or Vercel.

Troubleshooting Common Issues

• Code doesn't run: Check for syntax errors. Use your AI tool to help debug.
• App crashes: Ensure you’re handling errors properly in your code.
• Performance issues: Simplify your code and check for unnecessary loops or calls.

What's Next: Expanding Your Skills

Once your app is up and running, consider diving deeper into more complex features, like user authentication or database integration. Explore additional resources like:
