Cursor

Cursor is a groundbreaking AI-first code editor that has reimagined the development environment around AI assistance. Built on the VS Code foundation, Cursor provides all the familiar features of a professional code editor while deeply integrating AI capabilities that go significantly beyond what VS Code extensions can offer.

The editor's most powerful feature is its codebase understanding. Unlike AI code assistants that only see the current file, Cursor indexes the entire codebase and makes this context available to AI queries. Developers can ask questions like 'where is the authentication logic?' or 'how does the data flow from the API to the UI?' and receive accurate answers based on the actual codebase structure.

Cursor's chat interface enables natural language conversations about code, where developers can ask for help understanding complex code sections, request refactoring suggestions, or ask for explanations of how different parts of the codebase interact. The AI maintains conversation context and can perform multi-turn problem-solving discussions.

The editor's Composer feature enables AI-driven multi-file editing, where developers describe what they want to build or change and the AI modifies multiple files simultaneously to implement the requested change. This capability dramatically accelerates implementation of new features and refactoring projects.

Cursor supports multiple AI models including GPT-4, Claude, and its own models, allowing developers to choose their preferred AI backbone. The editor's command palette exposes AI capabilities throughout the editing workflow, making AI assistance available at every stage of development.
