Sourcegraph Cody is an AI-powered code assistant developed by Sourcegraph, designed to help developers understand, navigate, and write code more efficiently—especially in large and complex codebases. Unlike generic AI tools, Cody is deeply integrated into the Sourcegraph platform and leverages code graph technology to provide context-aware and repository-scale assistance.

Cody is built for professional software engineers working across monorepos, legacy systems, or enterprise-grade applications. It uses multiple AI models (including open and proprietary models) and combines them with Sourcegraph’s semantic search, symbol indexing, and code intelligence to deliver relevant, reliable code help.

Key strengths include:

• Repository-aware code assistance, not just file-level suggestions

• Advanced search and navigation, powered by Sourcegraph's code graph

• Multi-model support, allowing flexibility across coding contexts

What are the main features of Sourcegraph Cody?

Contextual code generation and completion

Cody generates and completes code based on a full understanding of your repository.

• Considers symbols, file structure, and dependencies

• Generates functions, config files, and patterns relevant to the project

• Reduces hallucinations by grounding output in real code

AI-assisted code navigation and exploration

Beyond generation, Cody helps developers explore unfamiliar codebases.

• Answers questions like “Where is this function used?” or “What does this service do?”

• Provides summaries of files, diffs, and PRs

• Saves time during onboarding, debugging, or reviewing legacy code

Natural language code search and Q&A

Cody supports natural language queries for code discovery and explanation.

• Enables questions like “How is authentication implemented?”

• Combines search results with AI-powered answers

• Useful for understanding large systems without manually tracing code

Multi-repo and monorepo support

Cody works across entire repositories and large monorepos without performance degradation.

• Handles deeply nested project structures and large code volumes

• Maintains context across files, modules, and services

• Built for modern, large-scale software environments

Integration with IDEs and Sourcegraph UI

Cody is available via the Sourcegraph web interface and through IDE extensions.

• Supports VS Code and JetBrains via plugins

• Inline suggestions and chat capabilities

• Works seamlessly with Sourcegraph’s search and navigation tools
