2025年2月3日2025年9月5日

Cursor is an AI-powered code editor developed by Anysphere Inc. that significantly improves programming efficiency. It is based on VS Code (Visual Studio Code) and supports development by having an AI assistant complete and modify code, as well as reference documentation.

Anysphere Inc. announced that it has raised $105 million in Series B funding from Thrive, Andreessen Horowitz, Benchmark, and existing investors. (January 17, 2025)
In addition, it has also announced $8 million in financing from OpenAI in the past.

Key Features of Cursor

1. AI-powered code completion

During programming, AI predicts the “code to write next” and automatically suggests it. For example, if you write a function halfway through, the AI will guess and complement the rest of the code, reducing the hassle of manual input.

2. Code editing in natural language

You can tell them with natural language like “speed up this function,” and the AI will optimize your code. You can also simply say, “Fix the bug in this code,” and the AI will find and fix the problem.

3. Understanding the Codebase

The AI analyzes the entire project and presents relevant code and documentation. For example, if you ask, “Where is this function used?”, the AI will show you the relevant code.

4. AI Chat Like ChatGPT

Like ChatGPT, it has a chat feature that allows you to ask questions about code. You can ask questions about the meaning of the error message or how to use certain technologies, and the AI will answer them.

5. GitHub integration

By integrating with GitHub, AI can also help you review pull requests and analyze change history. This also ensures that team development runs smoothly.

Note: The relationship between Cursor and VS Code (Visual Studio Code)

Cursor is an AI-powered code editor developed based on VS Code. Therefore, it uses the basic features of VS Code while adding powerful features such as AI-powered code completion, correction, and document reference.

Cursor is a fork of VS Code

Cursor is an editor created by forking (deriving) Microsoft’s VS Code.
Therefore, it has the same experience and UI as VS Code, and many VS Code extensions are also available.
However, Cursor adds unique AI capabilities, offering advanced code generation and modifications that VS Code alone cannot achieve.

Difference Between Cursor and VS Code

function	Cursor	VS Code
Base Editor	Forking VS Code	original
AI Complement	OpenAI API-based AI complement available	None (can be added with extensions)
Code Fixes	Contextual code modification is possible	None (Copilot etc. is required)
Extensions	Compatible with many VS Code extensions	Expandable from the official marketplace
GitHub integration	AI code review available	GitHub Basic Features and Integrations
price	Free and paid plans available (limited by AI features)	Completely free (some extensions are paid)

Summary

Cursor is an AI code editor that streamlines programming, making it accessible to both beginners and advanced users. Especially for those who are used to the usability of VS Code, it is attractive that it can be implemented smoothly. You can use the power of AI to write code faster and more accurately, so give it a try!
