Cursor is one of the most adopted AI code editors right now — and for good reason. It’s not just autocomplete bolted onto a text editor. It knows your codebase, understands context across files, and lets you chat with your code the same way you’d talk to a senior developer. This tutorial covers the features that matter most and how to actually use them.
Getting Started with Cursor
Cursor is a fork of VS Code, which means your existing extensions, themes, and keybindings carry over. Install it from cursor.com, sign in, and import your VS Code settings in one click. You’re up and running in under 5 minutes.
Choosing Your AI Model
Cursor lets you pick which model powers its suggestions. As of 2026, you can use Claude 3.7 Sonnet, GPT-4o, and others depending on your plan. For most coding tasks, Claude Sonnet offers the best balance of speed and code quality. Switch models in Settings → Models.
The Three Features You’ll Use Every Day
1. Tab Completion (Not Just Autocomplete)
Cursor’s Tab completion predicts your next edit — not just the next word. It watches what you’re doing and suggests the logical continuation. If you rename a variable, it’ll offer to rename all related uses. If you add a prop to a React component, it’ll suggest updating the interface. Press Tab to accept, Escape to dismiss.
2. Inline Edit with Cmd+K
Select any block of code, press Cmd+K (or Ctrl+K on Windows), and type what you want changed. Examples:
- “Refactor this to use async/await”
- “Add error handling”
- “Convert this to TypeScript”
- “Write a unit test for this function”
Cursor applies the change inline and shows a diff. You accept or reject with one key. This is where most developers save the most time.
3. Chat with Codebase Context (Cmd+L)
Press Cmd+L to open the chat panel. Unlike asking ChatGPT, Cursor’s chat has full context of your open files and project structure. You can ask things like:
- “Where is the user authentication logic handled?”
- “Why is this component re-rendering on every keystroke?”
- “How do I add pagination to this API route following the existing pattern?”
Use @filename to pull specific files into context, or @codebase to search the entire project.
Cursor vs GitHub Copilot: Key Differences
GitHub Copilot lives inside your existing editor as an extension. It’s excellent at line-by-line completions but has limited codebase awareness unless you’re on Copilot Enterprise. Cursor is a full editor replacement with deeper project context, multi-file edits, and a more capable chat interface built in by default.
- Copilot: Best if you want to stay in VS Code and just want smarter autocomplete
- Cursor: Best if you want an AI-first experience with chat, inline edits, and codebase search in one place
Both use similar underlying models, so the difference is mostly in the workflow, not raw code quality.
Tips for Getting Better Results
- Be specific in prompts. “Fix this” gets worse results than “Fix the null reference error on line 42 when the user array is empty.”
- Use .cursorrules. Add a
.cursorrulesfile to your project root to give Cursor permanent context about your stack, conventions, and preferences. - Don’t accept blindly. Always review the diff before accepting — especially for refactors. Cursor is fast but not infallible.
- Combine Tab + Cmd+K. Use Tab for small continuations and Cmd+K for intentional rewrites. They serve different purposes.
Pricing
Cursor has a free tier with limited completions and a Pro plan at $20/month that removes limits and unlocks all models. For most developers doing this full-time, Pro pays for itself quickly. There’s also a Business plan for teams with admin controls and SSO.
Conclusion
Cursor isn’t magic — it still requires you to know what you’re building. But it removes enough friction from the writing, refactoring, and debugging cycle that most developers who try it don’t go back. Start with Cmd+K on a real task in your current project and see how it fits your workflow.
