GitHub Copilot

Cursor is an AI-first code editor built as a fork of Visual Studio Code that integrates advanced AI capabilities directly into the development workflow. The editor provides intelligent code completion, natural language code generation, codebase-aware chat, and AI-powered code editing features that understand the full context of a project. Cursor's Tab completion goes beyond traditional autocomplete by predicting multi-line code edits, suggesting entire function implementations, and understanding the developer's intent from surrounding code context. The Composer feature enables developers to describe changes across multiple files in natural language and have the AI implement those changes simultaneously, making large-scale refactoring and feature development remarkably efficient. The built-in chat interface provides codebase-aware AI assistance — developers can ask questions about their code, request explanations, generate test cases, and get debugging help with full awareness of the project's file structure, dependencies, and coding patterns. Cursor supports all VS Code extensions, themes, and keybindings, meaning developers can migrate from VS Code with zero friction while gaining powerful AI capabilities. The editor connects to leading AI models including GPT-4, Claude, and custom models, allowing users to choose the AI backend that best suits their needs.
