📝 In-Depth Review
Cursor is built on VS Code but has nearly redefined the AI coding experience. Tab completion goes beyond single lines, often completing entire functions; Cmd+K inline editing — select code and directly say "add error handling" or "convert to async"; Chat sidebar understands full project context; Agent mode can auto-execute multi-step tasks (like "write unit tests, fix failing tests, then commit to git"). Supports multiple model switching including Claude, GPT-4o, and more — the fastest growing AI IDE of 2026.
🔬 Hands-On Experience
Ran three rounds of testing with Cursor: Round 1 was fixing a memory leak in a React component — in Composer mode with multiple files selected, the AI auto-identified a missing cleanup function in useEffect, generated the complete fix, and warned about closure trap risks. Round 2 used Tab completion to write a Node.js file upload middleware — completion accuracy was high, inferring error handling logic from existing multer configuration. Round 3 tested multi-file refactoring, splitting Express routes from app.ts into separate router files — the AI generated all import adjustments and route registration code in one go. The context understanding of Composer Ctrl+K is a highlight, maintaining cross-file associations even in large codebases. The only issues are high CPU usage on initial indexing and non-trivial subscription costs.
🎯 Use Cases
Generate complete React + Node.js project scaffolding from scratch, including frontend components, API routes, and database models
Split legacy monolithic code by module, AI auto-maintains functional consistency and type safety
Select error code and let AI analyze the stack trace and provide fixes, especially good at Promise chains and async errors
Let AI review PR diffs from performance, security, and maintainability dimensions and provide improvement suggestions
Auto-generate Playwright/Cypress test cases based on existing API routes and database schema
Auto-track all referencing files after type definition changes and sync updates, avoiding compilation errors from omissions
💡 Tips & Tricks
1. In Composer mode, after selecting multiple files with Ctrl+K, specify the project tech stack and architecture conventions in .cursorrules — AI output quality improves noticeably
2. For complex cross-file changes, first use @file to bring related files into Composer — don't let AI process more than 5 files at once
3. Use .cursorrules to define project coding standards, like "use React Query instead of useEffect for requests" and "all API responses must include a unified wrapper" — AI will strictly follow them
4. Review Cursor-generated code block by block with Diff Review, especially AI auto-generated import paths and type assertions which occasionally produce hallucinations

🆚 Comparison
Compared to GitHub Copilot, Cursor has stronger multi-file editing and code understanding capabilities, with Composer mode showing clear advantages in cross-file refactoring; but compared to Copilot's deep native VS Code integration, Cursor occasionally has index sync issues. Compared to Windsurf, Cursor's completion speed and context awareness are slightly behind, but it is more stable and reliable for large-scale project architecture-level tasks.
✅ Pros
- Extremely accurate Tab completion, often predicts the next 5-10 lines
- Cmd+K inline editing — select code and modify with natural language directly
- Agent mode auto-executes multi-step tasks
- Supports multiple model switching (Claude/GPT-4o, etc.)
❌ Cons
- Based on VS Code, occasional compatibility issues
- $20/mo, solo developers find it pricey
- Agent mode occasionally goes off track, needs manual correction
- Context handling under strain for large projects (500K+ lines)
