Features

• 🤖 Chatbot that knows your code: Writes code and answers questions with knowledge of your entire codebase, following your project's code conventions and architecture better than other AI code chatbots.
• ✨ Fixup code: Interactively writes and refactors code for you, based on quick natural-language instructions.
• 📖 Recipes: Generates unit tests, documentation, and more, with full codebase awareness.

Usage

1. Install the Cody VS Code extension.
2. Open Cody (from the activity bar or by pressing Alt+//Opt+/) and sign in.
3. Start using it! Read on to learn about the chatbot, fixups, and recipes.

🤖 Chatbot that knows your code

📽️ Demo

To start chatting with Cody, click on the Cody icon in the activity bar (or press Alt+//Opt+/, or run the Cody: Focus on Chat View command).

Examples of the kinds of questions Cody can handle:

• How is our app's secret storage implemented on Linux?
• Where is the CI config for the web integration tests?
• Write a new GraphQL resolver for the AuditLog.
• Why is the UserConnectionResolver giving an error unknown user, and how do I fix it?

Cody tells you which code files it read to generate its response. (If Cody gives a wrong answer, please share feedback so we can improve it.)

✨ Fixup code

📽️ Demo

Just sprinkle your code with instructions in natural language, select the code, and run Cody: Fixup (Ctrl+Alt+//Ctrl+Opt+/). Cody will figure out what edits to make.

Examples of the kinds of fixup instructions Cody can handle:

• "Factor out any common helper functions" (when multiple functions are selected)
• "Use the imported CSS module's class names"
• "Extract the list item to a separate React component"
• "Handle errors better"
• "Add helpful debug log statements"
• "Make this work" (seriously, it often works--try it!)

📖 Recipes

Select the recipes tab or right-click on a selection of code and choose one of the Ask Cody > ... recipes, such as:

• Explain code
• Generate unit test
• Generate docstring
• Improve variable names
• Translate to different language
