Cursor IDE

Cursor is an AI-first code editor built as a fork of VS Code that integrates deeply contextual AI code assistance including codebase-wide understanding, multi-file editing, natural language code generation, and an AI chat that can reference and modify code across the entire repository. Its Composer feature enables AI to make coordinated changes across multiple files simultaneously, enabling complex refactors and feature additions that single-file AI assistants cannot handle. Professional developers building complex applications use Cursor as their primary IDE for its superior AI integration that understands project architecture and enables significantly larger AI-assisted code changes than plugin-based AI coding assistants allow.
