In-Depth Review
Cursor rapidly rose to prominence in 2025-2026, almost single-handedly proving that "AI-first editor" is not a gimmick. It's built on VS Code's open source codebase, so if you previously used VS Code, migration is nearly zero-cost — all plugins, shortcuts, themes, and settings.json are fully compatible. The difference is that Cursor added a layer of AI engine, and this engine changes the way you write code.
The core feature is Tab completion. It's different from GitHub Copilot's completions — Copilot "guesses your next line based on context," while Cursor "guesses the next several lines or even the entire function based on context." And it doesn't just complete new code — it also predicts modifications you're about to make to existing code. For example, when you change a function signature, it automatically prompts you that all call sites need to sync with the modification. This "multi-step jump prediction" has an astonishingly high hit rate in real development — we tested a medium-sized React project and Tab completion accuracy was around 70%-80%, meaning most of the time you just press Tab to accept suggestions rather than manually typing code.
Another killer feature is inline editing (Cmd+K). Select a block of code, describe the modification you want in natural language — "turn this loop into map," "add error boundary to this component," "extract this logic into a custom hook" — Cursor modifies your code in place, rather than generating new code in a sidebar chat window for you to copy-paste. This experience difference seems subtle but feels completely different in actual use — it's more like a code-savvy colleague sitting next to you helping you edit, rather than a Q&A bot.
Chat mode (Cmd+L) is equally good. You can select an entire file or folder and ask "does this code have potential performance issues," "write unit tests for me," "explain this project's architecture." Because Cursor indexes the entire codebase with embeddings, its answers are far more precise than ChatGPT or Claude - it understands your project structure, variable naming conventions, and even the APIs of third-party libraries you've imported.
There are cons. The Pro $20/mo price isn't cheap among AI tools — especially if you're already paying $20/mo for ChatGPT Plus. The free tier's AI call quota is quite tight, exhausted within a day or two of heavy use. The AI model also occasionally "glitches" — especially when processing very obscure libraries or legacy code styles, suggestion quality noticeably drops. But overall, if you write code more than 4 hours a day, Cursor Pro is the most worthwhile $20 you can spend right now.
Pros
- AI code completion far surpasses Copilot
- Fully compatible with VS Code extensions
- Inline editing and conversational coding
Cons
- Pro at $20/mo isn't cheap
- Limited AI model quota
- Occasional suggestion quality fluctuation
