Cody by Sourcegraph leverages Sourcegraph's code intelligence technology to provide AI assistance with deep codebase understanding. Unlike AI tools that only see the current file, Cody understands your entire project structure, dependencies, and how different parts of your code relate to each other. This contextual awareness leads to more accurate and relevant suggestions. Cody can explain code, generate new code, find and fix bugs, write tests, and answer questions about your codebase. It integrates with VS Code, JetBrains IDEs, and Neovim. The chat interface lets you have conversations about your code with references to specific files and functions. For developers working on large, complex codebases where understanding context is crucial, Cody's code graph-powered intelligence provides significant advantages.
