CodiumAI is an AI tool that focuses on code integration, generating non-trivial tests to suggest proper code behavior, and helping developers write reliable and valuable code while spending fewer hours on test cases. The tool is available as a free VS Code extension or JetBrains plugin and currently supports Python and JavaScript/TypeScript languages, with Java support soon to come. CodiumAI takes security, privacy, and compliance seriously, with data SSL encryption and SOC2 certification, but it does not write perfect tests and encourages users to double-check generated tests. The tool has a community and FAQs section and offers early access to its VS Code and JetBrains products.
