What Cursor Is
Cursor is a code editor built from the ground up around AI. It is a fork of VS Code, which means the interface, keybindings, extensions, and settings you already know all work. The difference is that AI is woven into every layer of the editing experience rather than bolted on as an extension.
This architectural choice matters. When Copilot runs as an extension inside VS Code, it has limited access to your project context. When AI is the editor itself, it can read your entire codebase, understand file relationships, and make changes that account for how your project actually fits together.
After using Cursor as my primary editor for months across multiple Next.js and TypeScript projects, here is what I have found.
Tab Completion
Cursor's inline code completion is the feature you use most and notice least. As you type, Cursor suggests completions that appear as gray ghost text. Press Tab to accept.
What makes Cursor's completions better than Copilot's is the context awareness. Cursor uses a custom model optimized for low-latency autocomplete, and it draws from your entire project to inform suggestions. If you have a utility function defined three files away, Cursor knows about it and suggests using it in the right context. If your project follows specific naming conventions, Cursor picks up on them.
The completions are not always perfect, but across a full day of coding, the hit rate is high enough that Tab becomes second nature. The speed is the other factor. Suggestions appear almost instantly, fast enough that they do not interrupt your flow.
Composer Mode
This is Cursor's flagship feature and the primary reason to choose it over any other editor.
Composer lets you describe a change in natural language, and Cursor proposes edits across multiple files simultaneously. You see a diff for each affected file and can accept or reject changes individually.
Practical example: "Add authentication middleware to all API routes. Create a middleware function that checks for a valid JWT token in the Authorization header. Apply it to every route in the /api directory except /api/auth/login and /api/auth/register. Update the types file with the authenticated request type."
Composer reads the relevant files, understands the current structure, writes the middleware function, applies it to the correct routes, skips the excluded ones, and updates the types. You review the diffs and accept.
This kind of coordinated multi-file change is where developers spend enormous amounts of time. Composer compresses what might take an hour of careful manual editing into a five-minute review.
Chat
Cursor's chat panel lets you ask questions about your code, request explanations, and generate code snippets. You can reference specific files using @ mentions, which gives the AI precise context.
"@src/lib/auth.ts why does the token refresh fail when the session expires?" produces a targeted answer because the AI reads the actual file you referenced.
Chat is useful for debugging, understanding unfamiliar code, and getting quick implementations. It is less powerful than Composer for making actual changes but more convenient for quick questions and code generation.
Model Selection
Cursor supports multiple AI models: Claude Sonnet, Claude Opus, GPT-4, GPT-4o, and others. You can switch between them based on the task.
In practice, Claude Sonnet is the best default. It is fast, produces clean code, and handles most tasks well. Switch to Claude Opus when you need the AI to reason through complex architecture decisions or handle nuanced refactoring. GPT-4 is a solid alternative if you prefer OpenAI's models.
The ability to choose your model is a genuine advantage over Copilot, which locks you into GitHub's model selection.
The VS Code Foundation
Because Cursor is a VS Code fork, the transition from VS Code is essentially painless. Your extensions install from the same marketplace. Your keybindings work. Your settings sync. The terminal, debugger, source control, and all other VS Code features are present and functional.
The downside of being a fork rather than VS Code itself is that updates to VS Code take time to reach Cursor. A brand new VS Code feature might not appear in Cursor for weeks or months. In practice, this has not been a meaningful issue, but it is worth noting.
Pricing
The free tier gives you a limited number of AI completions and chat messages. It is enough to evaluate the tool thoroughly but not enough for daily professional use.
Cursor Pro at $20/month gives you significantly higher limits on completions, chat, and Composer uses. For a developer who codes daily, Pro is the appropriate tier.
Cursor Business at $40/user/month adds team features, admin controls, and higher limits.
Compared to GitHub Copilot at $10/month, Cursor costs more. The question is whether the additional capabilities (Composer, model selection, deeper context awareness) justify the premium. For developers working on complex projects with multiple interconnected files, the answer is almost always yes.
Who Should Use Cursor
Cursor is built for developers who write code as a significant part of their job. If you spend several hours a day in a code editor, Cursor's AI features will save you measurable time.
It is especially valuable for full-stack developers working on projects with many interconnected files (web applications, APIs with frontends, monorepos). The codebase awareness and Composer mode deliver the most value when the AI needs to understand how different parts of your system relate.
If you primarily write short scripts, work in notebooks, or do data science work, the value proposition is less clear. Cursor's strengths are in project-level coding, not isolated code snippets.
The Bottom Line
Cursor is the best AI code editor available in 2026. The combination of fast tab completion, codebase-aware context, multi-model support, and Composer mode creates a coding experience that is genuinely different from using VS Code with an AI extension.
Try the free tier for a week on a real project. If Composer saves you time on even one multi-file change, the $20/month pays for itself immediately.
