Cursor

AI-native code editor

Coding Application

What it's used for

Cursor is an AI-native code editor built on the VS Code foundation, designed to make AI a first-class participant in every step of the development workflow. Unlike bolt-on AI plugins, Cursor was built from the ground up to understand your entire codebase and use that context to generate, edit, and refactor code intelligently.

  • Codebase-aware chat — ask questions about your project and get answers grounded in your actual code, not generic documentation
  • Inline generation — press Ctrl+K to describe what you want and Cursor writes the code in place
  • Multi-file editing — use Composer mode to make coordinated changes across multiple files from a single instruction
  • Tab completions — context-aware autocomplete that predicts your next edit based on recent changes and cursor position
  • Code review & debugging — highlight errors, explain stack traces, and suggest fixes with full project context

Professional developers, startup engineers, and freelancers use Cursor as their primary editor because it dramatically reduces time spent on boilerplate, refactoring, and navigating unfamiliar code. It imports all VS Code extensions and settings seamlessly, so switching has essentially zero cost.

Cursor supports multiple AI models including GPT-4o, Claude Sonnet, and Claude Opus, letting developers choose the best model for each task. The Cursor documentation covers all features and keyboard shortcuts in detail.

Getting started

  1. Download the desktop app from cursor.com — available for Mac, Windows, and Linux.
  2. On first launch, Cursor offers to import your VS Code extensions and settings automatically. Accept this to bring over your themes, keybindings, and installed extensions.
  3. Sign in with your email or GitHub account to activate AI features.
  4. Choose your plan:
    • Hobby (Free): 2,000 completions/mo, 50 slow premium requests
    • Pro ($20/mo): Unlimited completions, 500 fast premium requests, access to GPT-4o and Claude models
    • Business ($40/user/mo): Centralized billing, admin dashboard, enforced privacy mode, SAML SSO
  5. Learn the essential shortcuts:
    • Ctrl+K / Cmd+K — inline code generation and editing
    • Ctrl+L / Cmd+L — open AI chat panel
    • Ctrl+I / Cmd+I — open Composer for multi-file edits
    • Tab — accept AI completions
Tip: Use .cursorrules files in your project root to give Cursor persistent context about your coding conventions, tech stack, and preferences. This dramatically improves the relevance of generated code.

6 hrs vs 3 days B2B SaaS

CRM Integration Built in 6 Hours, Not 3 Days

Growth-stage SaaS company

Challenge

A SaaS company needed a full Salesforce CRM integration (bidirectional sync, webhooks, field mapping UI) estimated at 3 days of engineering work by their team.

Solution

Used Cursor Composer with the existing codebase in context. Cursor generated the API client, webhook handlers, field mapping logic, and UI components. Iterative refinement in Composer addressed edge cases.

Results

Complete, production-ready CRM integration shipped in 6 hours. Code passed existing test suite without modification. The time savings allowed the feature to ship 2 weeks ahead of schedule.

34% → 87% test coverage Developer Tools

50k-Line Codebase Refactored — 34% to 87% Test Coverage

Series A developer tools company

Challenge

A 50k-line TypeScript codebase had only 34% test coverage, poor type safety, and inconsistent patterns accumulated over 3 years of fast growth. Technical debt was slowing new feature development.

Solution

Used Cursor with the full codebase indexed to systematically refactor patterns, add TypeScript strict mode types, and generate comprehensive test suites. Cursor's codebase understanding enabled project-wide changes without breaking changes.

Results

Test coverage from 34% to 87%. TypeScript strict mode enabled with zero type errors. New feature development velocity increased 40% in the month following the refactor.
