This extension is available in in visual studio marketplace for free. Download it from here


Once installed, you will see the codiumAI logo added to your VSCode activity bar and Status bar as show in the image below👇


By Clicking on the CodiumAI icon, you will be required to signup using email, GitHub or Google. After signup, you are all set to start using the amazing features that this too provides🥳

Exploring the feature commands

Having setup this extension in your developer environment, let me walk you through how to make the best out of it.

Creating Comprehensive Test Suites (/test):
This command is used to generate unit test suits for components or functions in your codebase.
To create unit test suites for your function, CodiumAI provides a shorthand command right on top of your function as shown in the image below.


You can directly click on the Test this function command to generate your test suits for that function.

You can as well use the CodiumAI chat icon from the Activity bar.
To do so, you will have to highlight the function you want to generate test suits for.
You will then use the command /test in the chat.


Code Analysis and Suggestions (/improve and /enhance):

CodiumAI's prowess extends beyond automated testing.
It also takes on the role of a diligent code inspector and advisor, offering developers valuable insights and suggestions to improve their code.

CodiumAI's code /improve and /enhance capabilities are engineered to ensure your code meets the highest standards of performance and correctness. Here's how it works:

  • In-Depth Examination: CodiumAI meticulously scrutinizes your code, going beyond surface-level checks. It delves deep into the codebase to identify potential issues and areas for improvement.
    It doesn't just spot problems; it offers suggestions for enhancing the performance of your code. These suggestions can range from optimizing algorithms to refining data structures, resulting in faster and more efficient code.

  • Readability: CodiumAI also go beyond just correcting your code, but also beautifies and make your codebase more cleaner for readability and understanding.

Automating Documentation with Docstrings (/docstring):
CodiumAI recognizes the significance of docstrings and simplifies the often tedious task of writing them. With this extension, you can automatically generate docstrings for your code, enhancing its documentation effortlessly. It ensures that your code is not only well-tested and optimized but also thoroughly documented.

What are Docstrings?

In many programming languages, docstrings are specially formatted comments or strings that serve as documentation for functions, methods, classes, and modules. They provide critical information about the purpose of the code, its inputs, outputs, and any other relevant details. Docstrings are a form of self-contained documentation, residing within the code itself, making it readily accessible to developers who work with the code.

Why docstrings are so valuable:

  • Clarity: Well-written docstrings make the code's purpose and functionality crystal clear. They eliminate ambiguity and reduce the need for time-consuming detective work to understand how a piece of code works.

  • Onboarding: For new team members or developers who encounter the code for the first time, docstrings are a lifeline. They provide context and insight, ensuring a smoother onboarding process.

  • Maintenance: As code evolves, docstrings serve as a reference for maintaining and updating it. They document the code's expected behaviour, allowing developers to make changes without fear of breaking functionality.

Imagine the time and effort saved as CodiumAI takes care of the mundane task of docstring generation, allowing you to focus on more creative and challenging aspects of your project. It streamlines the process of creating informative, well-structured docstrings, improving your code's readability and maintainability.


Let's recap the remarkable benefits of CodiumAI and why it's a must-have extension for you:

  1. Comprehensive Testing: CodiumAI automates the process of generating unit test suites, ensuring that your code is rigorously tested. Say goodbye to the time-consuming task of creating test cases manually, and embrace a testing process that is both thorough and efficient.

  2. Code Analysis and Optimization: CodiumAI's code analysis capabilities are unparalleled. It identifies areas for performance improvement and correctness, providing actionable suggestions that empower you to write code that not only works but works exceptionally well.

  3. Documentation Made Easy: The ability to automatically generate docstrings is a game-changer. It enhances code documentation effortlessly, ensuring that your code is not just functional but also comprehensible to you and your collaborators.

  4. Universal Language Support: CodiumAI supports all programming languages, breaking down language barriers and making its powerful features accessible to developers from diverse coding backgrounds.

  5. Code Quality and Maintainability: By automating testing, analysis, and documentation, CodiumAI contributes significantly to the overall code quality and maintainability. It simplifies complex tasks and allows you to focus on creative problem-solving.

  6. Time and Effort Savings: CodiumAI saves you precious time and effort. It handles the repetitive and mundane aspects of code development, allowing you to channel your energy into more meaningful and challenging tasks.

The power of CodiumAI lies in its ability to transform the way you develop software. It simplifies testing, enhances code analysis, and improves documentation, all while supporting your choice of programming language.
