Cody

Cody is Sourcegraph's AI coding assistant, and its killer feature is deep codebase understanding. While most AI coding tools only see the files you have open, Cody leverages Sourcegraph's code intelligence platform to search and understand your entire repository, including dependencies, type definitions, and cross-file references.

This means Cody can answer questions like "where is this function called?" or "how does authentication work in this project?" with real, grounded answers instead of guesses. The tool integrates with VS Code and JetBrains IDEs, providing inline completions, a chat panel, and commands for common tasks like generating unit tests, documenting functions, and explaining complex code.

Cody supports multiple LLM backends including Claude, GPT-4, and Mixtral, letting you choose the model that works best for your needs. For enterprise teams, Cody connects to your Sourcegraph instance, which can index hundreds of repositories simultaneously. This makes it uniquely powerful for large monorepos and microservice architectures where understanding cross-service interactions is critical.

The autocomplete is fast and context-aware, though the chat experience is where Cody truly outshines competitors thanks to its repository-wide search capabilities.
