Cursor

Cursor is a code editor that embeds AI assistance directly into the editing surface. It is built as a fork of VS Code, so extensions, themes, and keybindings carry over, but the assistant is a first-class part of the interface rather than a plugin. The core interaction is the inline edit: select code, describe the change in natural language, and review a diff before accepting. Alongside that, a chat panel can read the open files and answer questions about the codebase, and an agent mode can make multi-file changes with a plan the developer approves. The editor indexes the repository so answers reference the project's own code rather than generic patterns. Teams that adopt it typically keep a review step, because the assistant's output still needs the same scrutiny as any other contribution. The company publishes a changelog and documentation, which is what makes the feature set checkable.
