Cursor AI IDE Tutorial: How Good Is AI-Assisted Coding?
I've heard that Cursor can help people write code, modify code, and even refactor entire projects. But how do you actually use it? What's the difference between it and GitHub Copilot? Is it worth the money?

What is Cursor
Cursor is an AI-first code editor. It's built on top of VS Code, so all VS Code plugins and themes work with it.
The biggest difference from Copilot: Cursor doesn't just autocomplete code โ it understands your entire project.
Installation
Go to cursor.com to download and install. The free tier includes 2,000 completions per month, while Pro costs $20/month for unlimited usage.
Core Features
1. Tab Completion (Something Copilot Can Do Too)
As you type, Cursor shows predicted next code in gray. Press Tab to accept.
It's on par with Copilot, but with particularly strong support for Python/TypeScript.
2. Ctrl+K: Modify Code with Natural Language
Select a block of code, press Ctrl+K, and tell it what you want to change:
Convert this code to an async version
Add error handling
Write unit tests for this function
Translate the comments into Chinese
It makes the changes directly, and you can review the diff to decide whether to accept them.
3. Ctrl+L: Chat with AI About Your Code
No need to select code โ just press Ctrl+L to open the chat window. Cursor automatically knows which file you're currently viewing:
What does this function do?
Are there any bugs in this code?
How can I optimize this query?
It answers using the context of your entire project, not just the current file.
4. Agent Mode
This is Cursor's most powerful feature. Press Ctrl+Shift+P, type "Agent," and give it a task:
Create a Flask blog app for me,
with user registration and login,
using SQLite for the database,
and Bootstrap for the frontend.
Cursor will: 1. Create the project structure 2. Write app.py 3. Create template files 4. Install dependencies 5. Tell you how to launch it
You don't have to lift a finger throughout the whole process.
Comparison with Copilot
| Feature | Cursor | Copilot |
|---|---|---|
| Tab completion | Supported | Supported |
| Modify selected code | Ctrl+K | Not supported |
| Project context understanding | Global | Current file only |
| Agent mode | Supported | Not supported |
| Price | Free/$20 | $10 |
| Model selection | Claude/GPT options | Fixed model |
| Chinese understanding | Good | Average |
Practical Tips
- Use Agent for new projects โ easiest way to start from scratch
- Use Ctrl+K for code changes โ 3x faster than editing manually
- Use Ctrl+L for debugging โ paste the error message in
- Use Ctrl+K for writing tests too โ select a function and have it generate tests
- Use Ctrl+L for code review โ let AI check your code for issues
In One Sentence
Cursor turns coding from "typing" into "talking."
