Generating meaningful tests for busy devs
With CodiumAI, you get non-trivial tests (and trivial, too!) suggested right inside your IDE, so you can code smart, create more value, and stay confident when you push.
Code, as you meant it.
Write code that works
the way you meant it to
By analyzing your code, docstring, and comments, and by interacting with you,
TestGPT suggests tests as you code. All you have to do is accept and commit them.

āThis is a literal game changer.
Any newer dev that starts using this is going to be so far ahead of their competitionā

“Optimistic and inspired. Just tried the @CodiumAI tool today, and I think it is the first true 10x dev tool. I find it far more utilitarian than co-pilot.”

āI think a big portion of my shock was that I thought the tests were going to be just some random templates that didn’t do much. I didn’t think it would generate so many and they actually be detailed.ā

“I have already used @CodiumAI and would be glad to recommend it to the community to give a try āļø”

“damn, how is @CodiumAI free? It is a best automated unit writing experience I had so far”
#SoftwareDeveloper #DevOps

āI must say this VS code extension is amazing and saves a lot of time & effortā

āWriting less tests, not going to say no to that!
Have heard great things about Codium. On my lists to play around with.ā

CodiumAI isn't perfect
You should always double-check the tests CodiumAI generates
AI and ML have come a long way, but they're far from perfect. So while CodiumAI helps you break fewer things and be more productive, it needs your help to do so. That's why we designed it to be interactive ā so you can edit the tests it generates and perfect them.

I have a few
questionsā¦

Why donāt I just ask ChatGPT/Copilot to write my tests? How is CodiumAI different?
Unlike general-purpose code completion or generation tools, CodiumAI is focuses 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. CodiumAI is not another fancy āLanguage-model-API in your IDEā, because - a. Weāre pro at testing-domain prompting b. We parallelize and chain multiple prompts to create a unique variety of meaningful tests c. We efficiently gather broad code context for the prompts d. We let you interact on each test separately.

When will I be able to start using CodiumAI? Is it free?
You already can! Just download our free VSCode extension and/or JetBrains plugin and get meaningful tests. CodiumAI is free for individual developers, and we even plan to publish an open-source. In the future, we'll launch a paid plan for enterprises.
-
What languages are supported?
We support practically every programming language. However, some advanced features (such as unit-test run and fix) are only supported by Python, JavaScript, TypeScript, and Java. We support these in VSCode & JetBrains IDEs.
-
How does CodiumAI make sure my code stays secure?
We take security, privacy, and compliance very seriously. CodiumAI only analyzes the code necessary to give it enough context to generate meaningful tests, and the data is SSL encrypted. Also, we are SOC2 certified. To learn more, please visit our Trust Center.

Does CodiumAI write perfect tests?
AI and ML have come a long way, but nothing's perfect. While CodiumAI can boost your productivity and improve code integrity, please always double-check the tests it generates. We are here to give you superpowers, but you still need to think and use them wisely.
