Cursor IDE AI Editor

Cursor is a modern code editor forked from VSCode that integrates Claude, ChatGPT, and other language models directly into the development environment. Unlike extensions, Cursor is purpose-built for AI-first coding workflows—every keystroke, menu item, and UI pattern assumes you're working with an AI copilot. Features include inline code editing with AI suggestions, multi-message chat panels with full codebase context, automatic refactoring, and git diff awareness. It's become the default IDE for AI-first developers in 2025-26. Cursor runs on Windows, Mac, and Linux and maintains VSCode compatibility for most extensions and themes. It supports both subscription and perpetual plans, with Claude Pro integration for extended context windows.
