What Is Cursor AI and How Does It Work?

Cursor AI is a standalone code editor designed from the ground up to integrate artificial intelligence into every aspect of software development. Unlike plugins that add AI features to existing editors, Cursor rebuilds the development experience around AI assistance.

What exactly is Cursor AI?

Quick Answer: Cursor AI is an AI-powered code editor built on VS Code that uses large language models like GPT-4 and Claude to help developers write, understand, and modify code through natural language interactions.

The editor launched in 2023 and has quickly gained traction among developers frustrated with the limitations of AI autocomplete tools. Cursor takes a different approach by treating AI as a core part of the editing experience rather than an add-on feature.

At its foundation, Cursor uses the same architecture as Visual Studio Code. This means your existing extensions, themes, and keyboard shortcuts work out of the box. But on top of this familiar foundation, Cursor adds AI capabilities that understand your entire codebase, not just the file you currently have open.

To explore whether Cursor AI is a fork of VS Code, you can read this detailed analysis here.

‍

How does Cursor AI understand your codebase?

Quick Answer: Cursor creates an index of your entire project, allowing the AI to reference files, functions, and dependencies across your codebase when generating or explaining code.

This codebase-aware approach sets Cursor apart from tools like ChatGPT or basic autocomplete. When you ask Cursor to modify a function, it knows what other files import that function and can suggest appropriate changes across your project.

The indexing happens locally and updates as you work. Cursor processes your code structure, function signatures, import statements, and relationships between files. This context makes AI suggestions more accurate because the model understands your actual code rather than guessing based on the current file.

‍

Which AI models does Cursor use?

Quick Answer: Cursor supports multiple AI models including GPT-4, GPT-4o, Claude 3.5 Sonnet, and Claude 3 Opus, letting developers choose based on speed, cost, or capability needs.

This model flexibility matters because different models excel at different tasks. GPT-4 handles complex reasoning well. Claude tends to produce more detailed explanations. GPT-4o offers faster responses for quick completions.

Cursor also supports bringing your own API keys if you prefer using your existing OpenAI or Anthropic accounts directly.

‍

What Can You Actually Do with Cursor AI?

Understanding the features of Cursor AI is different from knowing how they apply to real development work. Here's what Cursor allows you to do in practice.

Can Cursor write code from natural language descriptions?

Quick Answer: Yes, Cursor can generate functions, classes, and entire files from plain English descriptions using its Composer feature, which creates code based on your instructions and existing codebase patterns.

The Composer feature lets you describe what you want in conversational language. You might type "create a function that validates email addresses and returns detailed error messages" and Cursor generates the implementation. The AI considers your project's existing code style and patterns.

This works for new code creation and for modifications. You can select existing code and ask Cursor to refactor it, add error handling, or convert it to a different approach.

For a comprehensive guide on using Cursor AI, refer to our article on How to Use Cursor AI.

‍

Does Cursor help with debugging and fixing errors?

Quick Answer: Cursor identifies bugs, suggests fixes, and can automatically apply corrections across multiple files when you describe the issue or paste error messages into the chat interface.

When your code throws an error, you can paste the error message directly into Cursor's chat. The AI analyzes the stack trace, examines the relevant code, and suggests specific fixes. Unlike generic AI assistants, Cursor knows your actual codebase and can trace issues across files.

The inline editing feature lets you highlight problematic code and ask for corrections without leaving your current context. Cursor suggests changes that you can accept, reject, or modify before applying.

‍

How does Cursor's autocomplete compare to GitHub Copilot?

Quick Answer: Cursor's autocomplete uses similar AI models to Copilot but benefits from deeper codebase context and offers more control over suggestion behavior through customizable settings.

Both tools predict what you intend to type next, but Cursor's approach includes awareness of your broader project structure. If you are writing a new function that should follow patterns established elsewhere in your codebase, Cursor references those patterns.

The autocomplete also supports multi-line suggestions and can complete entire code blocks based on comments or partial implementations. At LowCode Agency, we have found that developers who write good comments get significantly better suggestions from AI tools like Cursor.

‍

Can Cursor edit multiple files at once?

Quick Answer: Yes, Cursor's multi-file editing allows you to make coordinated changes across your codebase through a single natural language command, with diffs shown for review before applying.

This capability matters for refactoring work. When you rename a component, update an interface, or change a function signature, the ripple effects typically span multiple files. Cursor identifies affected files and proposes changes you can review as a batch.

The diff view shows exactly what will change in each file. You maintain control over what gets applied, but the AI handles the tedious work of finding and updating every reference.

Who Should Use Cursor AI?

Cursor fits certain developer profiles better than others. Understanding where it excels helps you evaluate whether it matches your needs.

Is Cursor good for beginners learning to code?

Quick Answer: Cursor helps beginners by explaining code, answering questions in context, and providing working examples, though learners should balance AI assistance with building fundamental understanding.

New developers benefit from Cursor's ability to explain unfamiliar code. You can highlight a block of code and ask what it does, and the AI explains it in plain language. This contextual learning accelerates understanding of new codebases and concepts.

However, relying too heavily on AI-generated code can slow down learning. The best approach combines using Cursor for explanations and examples while still practicing writing code yourself.

‍

Does Cursor work well for professional development teams?

Quick Answer: Cursor offers Business plans with team features, centralized billing, admin controls, and SOC 2 compliance certification for organizations requiring enterprise-grade security.

Professional teams benefit from consistent AI assistance across all developers. The Business plan includes features like usage analytics, admin dashboards, and the ability to enforce privacy settings across the organization.

Teams using Cursor report faster onboarding for new developers who can ask the AI questions about unfamiliar parts of the codebase. Code review processes also improve when developers use AI to catch issues before submitting pull requests.

‍

What programming languages does Cursor support?

Quick Answer: Cursor supports all programming languages that VS Code handles, including JavaScript, TypeScript, Python, Go, Rust, Java, C++, and dozens more through syntax highlighting and AI understanding.

Because Cursor builds on VS Code, language support matches what you expect from Microsoft's editor. Extensions for additional languages install the same way and work the same way.

The AI models perform better with popular languages that have more training data. Python, JavaScript, and TypeScript tend to produce the most accurate suggestions. Less common languages still work but may require more guidance in prompts.

How Does Cursor Compare to Other AI Coding Tools?

The AI coding tool landscape includes several options with different approaches and tradeoffs.

‍

Should you choose Cursor over GitHub Copilot?

Quick Answer: Choose Cursor if you want codebase-aware AI that can edit multiple files and respond to natural language commands. Choose Copilot if you prefer adding AI to your existing VS Code setup.

Copilot works as an extension, meaning you stay in VS Code with AI features layered on top. Cursor requires switching editors but provides deeper integration. The choice often comes down to whether you want to change editors or add to what you have.

Cursor's advantages show most clearly in larger projects where codebase awareness matters. For smaller projects or quick scripts, the difference narrows.

Is Cursor AI Worth the Cost?

Evaluating Cursor requires considering both direct pricing and productivity impact.

What does Cursor cost compared to alternatives?

Quick Answer: Cursor offers a free tier with limited requests, a Pro plan at $20/month with increased limits, and a Business plan at $40/user/month with team features and admin controls.

The free tier lets you evaluate Cursor with a limited number of AI requests per month. This works for occasional use but active development typically requires Pro.

Compared to GitHub Copilot at $10/month, Cursor costs more but offers different capabilities. The value calculation depends on whether those additional features justify the premium.

We have explained Cursor AI pricing in detail, If you want to understand the long-term cost of Cursor AI.

‍

Does Cursor actually make developers more productive?

Quick Answer: Developers using Cursor report 20-40% faster completion of common coding tasks, though actual productivity gains depend on task type, codebase complexity, and how effectively you use AI features.

Productivity improvements vary significantly by use case. Writing boilerplate code, understanding unfamiliar codebases, and fixing bugs show the largest gains. Creative problem-solving and architectural decisions benefit less from AI assistance.
