Cursor

What it is

An AI-powered code editor built on top of VS Code. It features a native AI chat, codebase indexing for context-aware answers, and "Composer" mode for multi-file edits.

What problem it solves

Provides a deeply integrated AI coding experience where the editor itself understands the full codebase context, enabling more accurate completions and multi-file refactors.

Where it fits in the stack

Development & Ops. Functions as a primary code editor with native AI capabilities.

Typical use cases

  • Context-aware code completion using codebase indexing
  • Multi-file edits via Composer mode
  • AI chat grounded in the current project

Strengths

  • Built on VS Code, so existing extensions and settings transfer easily
  • Codebase indexing provides deep context for AI responses
  • Composer mode supports complex, multi-file changes

Limitations

  • Proprietary; requires a subscription for full features
  • Dependent on external AI providers for model inference

When to use it

  • When you want an AI-native editor with deep codebase understanding
  • When performing frequent multi-file refactors or large-scale edits

When not to use it

  • When you prefer a fully open-source editor
  • When you want to use only local LLMs without cloud dependencies

Getting started

Download Cursor from the official website and sign in. On first run, it will index your codebase for AI context.

  1. Install: Download for your OS (Windows/Mac/Linux).
  2. Index: Let Cursor index your repository (check the status in the bottom right corner).
  3. Configure: Add your custom instructions in .cursorrules to guide the AI.

Usage examples

.cursorrules file

Create a .cursorrules file in your root directory to enforce coding standards: 

# Coding Standards
- Use TypeScript for all new files.
- Prefer functional components over classes.
- Use Tailwind CSS for styling.
- Ensure all functions have JSDoc comments.

keyboard shortcuts for AI features

Action Shortcut (Mac) Shortcut (Windows/Linux)
Edit code in place Cmd + K Ctrl + K
Chat with codebase Cmd + L Ctrl + L
Open Composer Cmd + I Ctrl + I
Apply Suggested Fix Cmd + Enter Ctrl + Enter

Practical notes

  • Cursor is strongest when rules, project memory, and model selection are treated as part of the editor setup rather than optional extras.
  • It overlaps with Claude Code on autonomous edits, but Cursor remains more editor-centric while Claude Code remains more terminal-centric.
  • It pairs well with reusable workflow systems such as Superpowers when you want stronger process control than the editor provides by default.
