Cursor is an AI code editor forked from Visual Studio Code that embeds large language model capabilities throughout the development workflow. Unlike standard editors with line-level autocomplete, Cursor indexes the entire project codebase and uses that context to generate suggestions that reflect existing patterns, imported dependencies, and file relationships across the full repository. Developers can issue natural language instructions through a chat panel to generate new code, refactor existing functions, explain unfamiliar logic, or apply coordinated edits across multiple files using the Composer feature. Cursor is used by software developers across experience levels, from students writing their first applications to professional engineers working on production-scale systems.
See related. A common workflow involves opening the Composer panel to describe a feature in plain language and having Cursor generate an implementation for review, then applying edits directly to the codebase. Teams use the inline chat to ask questions about unfamiliar codebases during onboarding, or to request targeted refactors without manually rewriting code. Cursor supports a broad range of programming languages including Python, JavaScript, TypeScript, Rust, Go, and others, and is compatible with most existing VS Code extensions and keybindings
