Cursor
AI-powered code editor with repo context.
Cursor is an AI-powered editor that understands your codebase. It helps with refactors, debugging, and multi-file edits.
What is Cursor?
Cursor is a modern development environment where AI is fully integrated into the code editor. Built as a VS Code fork, it supports all VS Code extensions and settings while adding a powerful AI layer on top.
Cursor's most notable feature is its ability to work by understanding the entire codebase. Rather than working with a single file, it builds context from the whole project to suggest multi-file changes, perform refactoring, and find the root causes of bugs. This is a significant differentiator compared to GitHub Copilot.
With Composer mode, Cursor automatically applies natural language instructions across multiple files, making it one of the strongest representatives of the "AI first" development approach. It was rapidly adopted in the developer community throughout 2024–2025.

Example Prompts & Expected Outputs
Copy and use these ready-made prompts directly.
Cmd+I → 'Add a password reset email feature to the existing user auth system. Use Resend API, token valid for 24 hours'
Cursor automatically creates: ✅ /api/auth/forgot-password.ts — token generation and email sending ✅ /api/auth/reset-password.ts — token verification and password update ✅ emails/reset-password.tsx — email template ✅ prisma/schema.prisma — PasswordResetToken model added ✅ Relevant tests automatically generated
Select buggy code → Cmd+K → 'Find the root cause of this error and fix it. What should I do to prevent similar issues?'
Error: TypeError: Cannot read properties of undefined (reading 'map') Root Cause: .map() is called before the API response arrives. Fix: Add optional chaining: data?.items?.map(...) Prevention: Add API response type validation or check loading state. Suggested change: - const items = data.items.map(...) + const items = data?.items?.map(...) ?? []
Select old callback-based code → Chat → 'Rewrite this code using async/await, strengthen error handling'
// Old (callback)
getUserData(id, function(err, user) {
if (err) console.log(err);
getPosts(user.id, function(err, posts) { ... });
});
// New (async/await)
async function getUserWithPosts(id: string) {
try {
const user = await getUserData(id);
const posts = await getPosts(user.id);
return { user, posts };
} catch (error) {
throw new Error(`Failed to fetch user data: ${error.message}`);
}
