Cursor — AI Glossary

Cursor is an AI-powered code editor built as a fork of Visual Studio Code, developed by Anysphere. It integrates large language model capabilities directly into the editing experience — autocomplete, inline chat, multi-file edits, and codebase-aware suggestions — so developers get AI assistance without leaving their editor. Unlike terminal-based agents, Cursor keeps you in a familiar IDE workflow while layering on AI-driven productivity features.

Why Cursor Matters

Cursor popularized the idea of embedding frontier LLMs directly into the editing loop rather than treating AI as a separate chat window. Its Tab autocomplete goes beyond single-token suggestions, predicting multi-line edits based on your recent changes and project context. The Composer feature handles multi-file modifications through natural language instructions, bridging the gap between chat-based AI and hands-on coding.

For teams evaluating AI development tools, Cursor represents the IDE-integrated approach — in contrast to agentic terminal tools that operate autonomously. Our coverage of AI coding tool developments tracks how these two paradigms are evolving.

How Cursor Works

Cursor wraps VS Code's editor core with an AI layer that routes requests to multiple model providers. Key mechanisms:

  • Codebase indexing: Embeds your project files into a vector store for context-aware retrieval, so the model sees relevant code beyond the open file
  • Multi-model support: Routes to Claude, GPT-4, and other models depending on task type and user preference
  • Inline diffing: Proposed changes appear as inline diffs you accept or reject, keeping you in control of every edit
  • Chat + Apply: Describe a change in chat, then apply the suggested diff directly to your file with one click

Cursor offers a free tier with limited completions, a Pro plan, and a Business plan with team features and admin controls.

  • GPT-54: One of the frontier models available as a backend provider within Cursor's multi-model architecture
