CodiumAI is an AI tool that provides meaningful code tests for busy developers. It suggests non-trivial tests directly in the integrated development environment (IDE), helping developers code smarter, create more value, and maintain confidence when pushing code. By analyzing code, docstrings, and comments, CodiumAI uses AI models to suggest tests as developers code, which can be easily accepted and committed. It offers full visibility of code behavior and the ability to understand how code changes affect the rest of the code. CodiumAI saves time by generating useful tests, allowing developers to focus on developing features for users. The tool goes beyond code completion and generation by helping improve code integrity, identifying edge cases and suspicious behaviors. It supports various programming languages such as Python, JavaScript, TypeScript, and will soon support Java. CodiumAI is free for individual developers and plans to offer a paid plan for enterprises.
