Cody — AI Coding Assistant by Sourcegraph

What is Cody?

Cody is an AI coding assistant by Sourcegraph that has deep understanding of your entire codebase. Unlike simple autocomplete tools, Cody uses Sourcegraph's code intelligence to search across your whole repository, read relevant files, and provide answers grounded in your actual code — not generic patterns.

Answer-Ready: Cody is Sourcegraph's AI coding assistant with full codebase context. It searches your entire repository using code intelligence, reads relevant files, and provides accurate answers and code generation grounded in your actual codebase. Works with Claude, GPT, and Gemini.

Best for: Developers working on large codebases who need context-aware AI assistance. Works with: VS Code, JetBrains, Neovim, web. Setup time: Under 3 minutes.

Core Features

1. Full Codebase Context

Cody searches your entire repository to answer questions:

You: "How does authentication work in this project?"
Cody: Searches repo → finds auth middleware, JWT config, user model
      → explains the full auth flow with file references

2. Code Search Integration

Powered by Sourcegraph's code intelligence:

You: "Where is the payment processing logic?"
Cody: Found in 3 files:
  - src/services/payment.ts (main logic)
  - src/api/routes/checkout.ts (API endpoint)
  - src/workers/payment-processor.ts (async processing)

3. Inline Completions

Context-aware autocomplete as you type:

// Cody knows your project's patterns
function createUser(data: CreateUserInput) {
  // Cody suggests based on your existing code patterns,
  // not generic boilerplate
}

4. Multi-Model Support

5. Commands

Built-in commands for common tasks:

6. Context Sources

Cody pulls context from:
├── Current file
├── Open files in editor
├── Repository-wide search
├── @-mentions (specific files/symbols)
└── Sourcegraph code graph (enterprise)

7. @-Mentions for Precise Context

You: @src/auth/middleware.ts explain the rate limiting logic
You: @UserService how does user deletion cascade?
