About Cursor

Cursor provides a code-first development environment with integrated AI coding models, context-aware agentic workflows, and plan-based token usage for built-in model access. It is not primarily a model provider API, so model access is typically via the Cursor platform.

Cursor is an AI-powered coding platform and IDE from Anysphere, focused on agentic software engineering workflows.
