Ultra-fast, low-memory AI productivity and refactoring engine for Visual Studio.

The AI-native code editor built for hyper-productive software engineering.

Cursor is a high-performance fork of VS Code, engineered from the ground up to integrate Large Language Models (LLMs) into the core developer workflow. Unlike traditional IDE plugins that operate as sidebars, Cursor treats the AI as a first-class citizen with deep access to the filesystem, terminal, and git history. Its technical architecture centers on a sophisticated codebase indexing system that creates local vector embeddings of your repository, enabling hyper-contextual responses via Retrieval-Augmented Generation (RAG). By 2026, Cursor has solidified its market position as the leading 'AI-native IDE,' moving beyond simple autocomplete to 'Composer' modes that generate entire multi-file features from natural language prompts. It supports cutting-edge models like Claude 3.5 Sonnet and GPT-4o, while offering a proprietary 'Cursor-Small' model for low-latency editing. The platform represents a shift from 'coding with AI assistance' to 'AI-driven system architecture,' where the developer acts as a high-level reviewer and orchestrator rather than a syntax writer.

A multi-file editing environment that allows the AI to create, delete, and modify multiple files simultaneously based on a single prompt.
Generates and stores local vector embeddings of the entire project to provide the LLM with relevant code context for every query.
Users can point Cursor to any documentation URL, which it then crawls and indexes for immediate reference during coding sessions.
A proprietary model that predicts the next location and content of an edit before the user starts typing.
Project-specific configuration files that define coding standards, architectural patterns, and prohibited practices.
Allows the AI to see terminal output and suggest commands to fix errors (e.g., missing dependencies).
An invisible background process where the AI attempts to run or lint code to verify it before presenting it to the user.
Download the Cursor installer for your OS (Windows, macOS, Linux).
Authenticate using GitHub or Google to sync settings and preferences.
Import your existing VS Code extensions and themes with one click.
Grant permission for Cursor to index your local repositories for RAG-based context.

Verified feedback from other users.
"Users praise Cursor for its 'magical' context awareness and the seamless transition from VS Code. It is widely considered the first tool that makes 'AI coding' feel like a native experience rather than an afterthought."
