What We Actually Use

In our experience, GitHub Copilot and Tabnine are our go-to tools for everyday coding. They help us save time and reduce errors while writing code. For code reviews, we rely on DeepCode, especially when working on larger projects.

Step-by-Step: How to Use AI Tools to Improve Your Code

Now that you know which tools to consider, let’s break down how to use them effectively in just 30 minutes.

1. Select Your AI Tool: Choose one or two tools from the table above based on your specific needs. For example, if you want code suggestions, go with GitHub Copilot.

2. Set Up Your Environment: Install the necessary plugins or set up your account with the chosen tool. Most tools have integrations with popular IDEs.

3. Load Your Codebase: Open the project you want to improve. Make sure it’s a clean working environment to avoid distractions.

4. Run the Tool: Use the AI tool to analyze your code. For instance, with DeepCode, you can run a code review that will highlight potential issues.

5. Implement Suggestions: Review the suggestions provided by the AI tool. Implement changes directly in your codebase. Focus on critical suggestions that will improve performance or fix bugs.

6. Test Your Code: After making changes, run your tests to ensure everything works correctly. Make adjustments as necessary.

7. Document Changes: Keep notes on what changes you made and why. This will help you understand the impact of AI suggestions on your code quality.

Troubleshooting Common Issues

• Misunderstood Suggestions: Sometimes AI tools might suggest changes that don't fit your context. Always review suggestions critically.
• Integration Problems: If a tool doesn’t integrate well with your IDE, check the documentation or consider switching tools.
• Feature Limitations: Some tools may not support the languages or frameworks you are using. Be clear about what you need before selecting a tool.
