Cursor

Cursor is an AI-first code editor built on VS Code, designed specifically for AI-assisted development. It combines the familiarity of VS Code with purpose-built AI features: Cmd+K for code generation, Cmd+Shift+L for codebase-aware chat, and Tab for autocomplete. Cursor understands your entire repository structure, allowing it to make intelligent suggestions that respect your project's architecture and conventions. Unlike GitHub Copilot (autocomplete-focused), Cursor emphasizes deep understanding of your codebase through retrieval-augmented generation—it can search files, understand dependencies, and make changes that align with your project. The editor supports both Claude and GPT-4 models, letting developers choose their preferred AI. For teams working on complex codebases, Cursor significantly speeds up refactoring, feature implementation, and debugging.
