Cursor

Cursor is an AI-powered integrated development environment (IDE) based on Visual Studio Code. It integrates AI assistance directly into the editor with project-aware chat, tab completion, and in-line edits, and it lets you @-reference files or folders to supply precise context to the model during code generation and refactoring.

Cursor supports project-scoped Rules stored under .cursor/rules/ to persist guidelines and domain knowledge across a codebase, and it provides background agents that can run tasks asynchronously in isolated remote environments while you review or take over their work. The editor preserves a VS Code workflow and allows migration of settings and extensions.
