Cursor

Cursor is an AI-powered code editor developed by Anysphere. It integrates GPT-3.5 and GPT-4.0 models, supporting multiple programming languages including Python, Java, C#, and JavaScript. Through shortcut key operations, it enables functions such as automatic code generation, editing, and discussion, significantly enhancing development efficiency124. Additionally, Cursor offers advanced features like code refactoring, comprehension, and optimization47. It provides 200 free uses of GPT-3.5 and 50 uses of GPT-4.0 per month, meeting the demands of most users16.

The main features of Cursor

• Code Generation: Cursor can automatically generate code based on developer instructions or code context, saving time on writing foundational code147.(Example: Input natural language like “Create a Python function to calculate list averages” triggers code generation)
• Intelligent Code Completion: Provides precise code completion suggestions (via Tab key) and predicts multi-line edits to accelerate coding1616. (Supports Python/Java/JavaScript/C# with contextual awareness)
• Bug Detection and Fixing: AI identifies errors in real-time and provides repair suggestions (e.g., syntax corrections, logic fixes), significantly reducing debugging time91017. (Includes performance optimization and security vulnerability detection)
• Code Explanation: Offers detailed explanations of code functionality when developers select specific code blocks (activated via Ctrl/Command+L)5717. (Supports visual execution flow diagrams for complex logic)
• Documentation Generation: Automatically generates project documentation like README files and API references through Ctrl/Command+Shift+D1314. (Customizable templates and batch export to Markdown/HTML/PDF)
• Code Optimization Suggestions: Analyzes existing code to provide quality/performance improvements (e.g., algorithm upgrades, variable renaming, loop simplification)717.(Supports design pattern recommendations like Factory Method)
• Multi-Language Support: Works with Python, Java, JavaScript, C#, Go, etc., covering full-stack development needs147.(Integrated terminal supports natural language command generation)
