Cursor is an AI-powered code editor built on VS Code that integrates frontier AI models directly into the development workflow. It features Agent mode for multi-file edits, Tab completion for intelligent code suggestions, and Background Agents that can work on tasks autonomously. Cursor supports multiple AI models including Claude, GPT, and Gemini, with an Auto mode that intelligently selects the best model for each task. The editor uses a credit-based system where subscription fees include a matching dollar amount of credits for premium model usage. Key capabilities include large context windows for understanding entire codebases, inline chat for asking questions about code, and terminal command generation. Cursor is designed for individual developers and teams, with enterprise features including SCIM 2.0 provisioning, audit logs, pooled usage credits, and granular admin controls. It has rapidly gained popularity among professional developers for significantly boosting coding productivity.
