If you're looking to code faster, fix bugs quicker, and ensure your coding is ready to perform, you might be interested in using AI tools. Artificial intelligence can make programming easier and faster by offering suggestions for improving code and automating repetitive coding tasks.

Discover some of the best AI tools for coding, and learn how edX's AI certificates, courses, and degree programs can help you build the skills to use them effectively.

5 AI tools for coding

AI tools have made it possible for developers of all skill levels to write, test, and improve code. Below are a few of the best AI tools for coding to support faster development with fewer errors.

These tools are in alphabetical order rather than ranked.

Amazon Q Developer

Amazon Q Developer is a generative AI assistant that can write code for you based on your prompts. If you'd rather do the heavy lifting and write your own code, the tool can make the process easier and more efficient by updating dependencies, optimizing code, and even making your code more secure. You can also save time by using built-in AI agents to test and document your code.

ChatGPT

ChatGPT is OpenAI's generative AI chatbot. While you can prompt ChatGPT to generate code, it works best for small code snippets or as a coding assistant. For example, if you want to add a script to a webpage, you can instruct ChatGPT to create the script code. Then, continue prompting the chatbot to fine-tune and optimize your code, if needed.

If you have ChatGPT Pro, you can access Codex, which OpenAI designed for coding tasks. Trained to prevent malicious code and offer transparency through detailed task logging, Codex generates code reflecting common development practices and standards.

Claude

Anthropic designed its AI assistant Claude to make smart coding decisions through a deep understanding of prompt context. Claude features multiple models, including Sonnet and Opus, to work with all types of code, from simple to complex. Its agentic AI enables Claude to search and edit entire databases autonomously to make multi-file changes efficiently.

GitHub Copilot

GitHub Copilot is an AI-powered coding assistant that works within popular coding editors, like Visual Studio Code and Neovim. It runs alongside you as you code to suggest edits or answer technical questions to help you problem-solve. Switch between AI models, such as Google Gemini 2.0 Flash and Claude 3.7 Sonnet, to tailor responses to your coding style and project needs.

Qodo

Qodo generates, reviews, optimizes, and tests code. It uses context-aware AI to suggest coding changes based on your codebase's structure and best practices. Rather than simply generating code, Qodo also helps you better understand code optimization by generating tests to expose unexpected behaviors and strengthen your code's reliability.

Learn AI with edX

The more you know about AI, the more confident you may feel using these AI coding tools. Consider learning AI with edX to strengthen your knowledge:

1. Enroll in an AI course or program to build a strong foundation of core concepts.
2. Earn an AI certificate in a specific subject area, like machine learning or data science. A great place to start is Harvard's CS50: Computer Science Courses and Programs, which offers hands-on experience with foundational AI and coding concepts.
3. Build on what you've learned with an AI bachelor's degree or a master's degree in AI.
4. Become an AI subject expert with an AI executive education program.
