Cursor

What Is Cursor?

Cursor is an AI-first code editor, built as a fork of Visual Studio Code, that integrates large language models directly into the development environment. Unlike standard plugins, Cursor is designed from the ground up to index your entire codebase, allowing the AI to have full context of your project’s structure, files, and dependencies. In 2026, it features an advanced “Agent Mode” that can independently plan and execute complex, multi-file changes based on high-level natural language instructions.

Where You Can Use It

You can use Cursor as a standalone Desktop application for deep development work. It also provides a Web-based interface through its Cloud Agents, which allow users to interact with repositories and generate artifacts directly in a browser. For developers on the move, its Mobile Agent access enables users to troubleshoot issues or review code remotely. Furthermore, Cursor offers an API and supports the Model Context Protocol (MCP) to connect with external tools like Jira, Notion, and Slack.

What It’s Known For

Cursor is best known for its “Codebase Indexing,” which enables it to answer project-specific questions and provide “Tab-Tab-Tab” predictive completions that feel telepathic. It is highly regarded for its “Composer” feature, which allows users to build entire applications or features across multiple files simultaneously. Beyond pure coding, it has become a favorite for “Vibe Coding”—allowing developers and marketers alike to build custom automation scripts and PPC tools simply by describing what they need.
