Deep Copilot is a free, open-source extension for VS Code that adds an AI coding assistant directly into your editor. It connects to DeepSeek's AI to understand your code, answer questions, read and write files, search through your project, run commands, and even look things up on the web. Everything happens in a chat panel on the side of your screen - you type a question or request, and the AI responds with streaming text, code, and actions. It has safety features like approval dialogs for dangerous operations (deleting files, running shell commands), supports multiple chat sessions, and can remember your preferences across projects. The extension is self-contained - no backend server needed, everything runs inside VS Code.
How It Works
You hear about Deep Copilot - an AI coding assistant that lives right inside your VS Code editor, ready to help whenever you need it.
You find it in the VS Code extension store, click install, and a friendly whale icon appears in your sidebar. Everything is ready in seconds.
You click the key button, paste your DeepSeek API key, and save. Now your personal coding assistant is awake and ready to help.
You click the whale icon to open the chat panel and type questions like 'explain this function' or 'help me fix this bug'. The AI responds instantly with streaming text.
It reads your files, searches for patterns, and understands your project structure without you lifting a finger.
It writes new files, edits existing code, or applies changes - asking your permission for big changes to keep everything safe.
It searches your code or the web to find answers, documentation, or solutions to tricky problems.
Everything happens in your sidebar - streaming responses, code blocks you can run or copy, file changes applied right before your eyes. You stay in control the whole time.
What used to take hours of searching and typing now happens in seconds. You have a tireless coding partner who understands your project and helps you build faster.
