What We Actually Use

• GitHub Copilot for code suggestions.
• Replit for quick prototyping.
• Ponic for building MVPs without coding.

Step 2: Set Up Your Development Environment

1. Install Your IDE: Download and install Visual Studio Code or use Replit's online IDE.
2. Set Up GitHub Copilot: If using GitHub Copilot, install the extension in your IDE.
3. Create a New Project: Start a new project in your chosen IDE or platform.

Step 3: Build Your App

1. Define Your App’s Purpose

Keep it simple. Decide on a core function for your app, like a to-do list or a weather checker.

2. Use AI Tools to Generate Code

• Start typing the basic structure of your app, and let GitHub Copilot suggest code snippets.
• If you get stuck, ask ChatGPT for help on specific coding issues.

3. Test as You Go

Run your app frequently to ensure everything works. Use Replit’s built-in testing features or run a local server in your IDE.

4. Iterate Based on Feedback

Show your app to a friend or fellow builder and get feedback. Use this to make quick adjustments.

Troubleshooting: What Could Go Wrong?

• Code Errors: If you encounter bugs, consult ChatGPT or use GitHub Copilot for suggestions.
• Deployment Issues: If your app doesn’t run, ensure all dependencies are installed and configured properly.

What’s Next?

Once you’ve built your app, consider these next steps:

• Add Features: Use AI tools to enhance your app with new functionalities.
• Launch: Deploy your app using platforms like Heroku or Vercel.
• Get User Feedback: Share your app with potential users to gather insights for improvement.

Conclusion: Start Here

Building a simple app using AI coding tools can be done in just 2 hours if you choose the right tools and approach. Start with GitHub Copilot and Replit for coding assistance and prototyping, respectively. Don’t hesitate to leverage ChatGPT for troubleshooting and brainstorming.

By following these steps, you'll not only build your app but also gain confidence in using AI tools for future projects.
