Best AI Code Refactoring Tools

Compare the Top AI Code Refactoring Tools as of April 2025

What are AI Code Refactoring Tools?

AI code refactoring tools are software tools that leverage artificial intelligence to automate the process of improving and restructuring existing code without changing its external behavior. These tools analyze the codebase for inefficiencies, inconsistencies, or redundant patterns and suggest or make changes that enhance readability, performance, and maintainability. By using machine learning algorithms, AI refactoring tools can also predict potential issues and offer solutions based on best coding practices. This process helps developers optimize their code while reducing the chances of introducing bugs during refactoring. Overall, AI-driven tools streamline the refactoring process, enabling faster and more efficient development cycles. Compare and read user reviews of the best AI Code Refactoring tools currently available using the table below. This list is updated regularly.

    Qodo

    Qodo

    Qodo

    Qodo (formerly Codium) analyzes your code and generates meaningful tests to catch bugs before you ship. Qodo maps your code’s behaviors, surfaces edge cases, and tags anything that looks suspicious. Then, it generates clear and meaningful unit tests that match how your code behaves. Get full visibility of how your code behaves, and how the changes you make affect the rest of your code. Code coverage is broken. Meaningful tests actually check functionality, giving you the confidence needed to commit. Spend fewer hours writing questionable test cases, and more time developing useful features for your users. By analyzing your code, docstring, and comments, Qodo suggests tests as you type. All you have to do is add them to your suite. Qodo is focused on code integrity: generating tests that help you understand how your code behaves; finding edge cases and suspicious behaviors; and making your code more robust.

    CodeGeeX

    CodeGeeX

    AMiner

    We introduce CodeGeeX, a large-scale multilingual code generation model with 13 billion parameters, pre-trained on a large code corpus of more than 20 programming languages. Based on CodeGeeX, we develop a VS Code extension (search 'CodeGeeX' in the Extension Marketplace) that assists the programming of different programming languages. Besides the multilingual code generation/translation abilities, we turn CodeGeeX into a custom programming assistant using its few-shot ability. It means that when a few examples are provided as extra prompts in the input, CodeGeeX will imitate what are done by these examples and generate codes accordingly. Some cool features can be implemented using this ability, like code explanation, summarization, generation with specific coding style, and more. For example, one can add code snippets with his/her own coding style, and CodeGeeX will generate codes in a similar way. You can also try prompts with specific formats to inspire CodeGeeX for new skills.
