Cursor

Definition

Cursor is an AI-native code editor, forked from VS Code, that builds deep AI assistance directly into the editing experience — including chat, multi-file code generation, and agentic editing — rather than treating AI as a bolt-on extension.

Overview

Cursor started from the familiar foundation of VS Code — keeping its extension ecosystem, keybindings, and general interface — but redesigned the core editing experience around large language models rather than adding AI as an afterthought. Instead of a single autocomplete suggestion, Cursor lets developers chat with an AI about their codebase, ask for multi-file edits, and review AI-proposed diffs before accepting them. A key differentiator is its "agentic" editing mode, where the AI can plan and execute a multi-step task across several files — reading relevant code, making edits, running commands, and iterating based on results — with the developer supervising rather than writing every line manually. Cursor indexes a project's codebase to give the underlying models better context about existing patterns, conventions, and dependencies before generating new code. Cursor competes with other AI-assisted coding tools such as GitHub Copilot, and it can be configured to use models from multiple providers, including Anthropic and OpenAI. It has become a prominent example of the broader shift toward AI-assisted development workflows often referred to as agentic coding, a trend explored further in The 2026 AI Engineer Roadmap: Skills, Tools, and Career Path.

Key Features

• Forked from VS Code, preserving familiar UI, keybindings, and extensions
• In-editor AI chat with awareness of open files and project context
• Multi-file code generation and editing with reviewable diffs
• Agentic mode that plans and executes multi-step coding tasks autonomously
• Codebase indexing for more contextually relevant AI suggestions
• Support for multiple underlying AI model providers
• Inline autocomplete that predicts multi-line edits, not just single tokens

Use Cases

History

Cursor is an AI-first code editor — a fork of Visual Studio Code with AI capabilities built into the core rather than added as an extension — designed to understand an entire codebase and to autocomplete, explain, and autonomously edit code. It is built by Anysphere, founded in 2022 by four MIT students: Michael Truell, Sualeh Asif, Arvid Lunnemark, and Aman Sanger. The team went through OpenAI's startup accelerator, and Cursor launched in March 2023. It became one of the fastest-growing developer tools of the AI era, popularizing chat-based and agentic coding workflows integrated directly into the editing environment.
