VS Code + AI Extensions

Add powerful AI to the world's most popular editor — Copilot, Claude, or Codeium

VS Code is the most-used code editor in the world. With the right AI extensions, it becomes a powerful AI-assisted development environment. Unlike Cursor or Windsurf, you don't switch editors — you supercharge the one you already know. Three main AI options: GitHub Copilot, the Claude extension, and Codeium (free).

🐙

⚡ Install & Setup — GitHub Copilot

Install VS Code

Download from code.visualstudio.com. Free, runs on Mac, Windows, and Linux.

Install the Copilot Extension

Open VS Code → Extensions panel (Cmd+Shift+X) → search "GitHub Copilot" → Install. Also install "GitHub Copilot Chat" for the chat panel.

Click the Accounts icon (bottom-left) → Sign in with GitHub → authorize. Your GitHub account needs an active Copilot subscription ($10/month, or free for students/open-source).

Verify It's Working

Open any code file and start typing. Gray ghost text appears as Copilot suggestions. Press Tab to accept.

⚡ Install & Setup — Codeium (Free)

Install Codeium Extension

Extensions panel → search "Codeium" → Install. Codeium is free forever — no subscription needed.

Create Free Account

Start Coding

Inline completions activate immediately. Open Codeium Chat with Cmd+Shift+A for the chat panel.

💡 Pro Tips

Write descriptive comments above a function before implementing it — Copilot uses them as a spec
Install both "GitHub Copilot" and "GitHub Copilot Chat" — they are separate extensions
Copilot is free for verified students and open-source maintainers (check github.com/education)
Use @workspace in chat to ask questions about your entire project, not just the open file
Codeium has no rate limits and no credit card — ideal for learners who don't want to pay yet
