Cursor is an AI coding tool from Anysphere, Inc. in which developers plan, write and test software with agents. It offers inline AI edits, agents that work in parallel including cloud agents, code review on GitHub pull requests, and a choice of models from several providers, including Cursor's own. It is delivered as a desktop app, a terminal CLI and a web agent.
Anysphere is based in San Francisco and, since August 2026, is a wholly owned subsidiary of SpaceX, a US company. According to Cursor, requests go through its own backend even with a personal API key and are forwarded to model providers such as OpenAI, Anthropic and SpaceXAI. With Privacy Mode on, Cursor states that customer data is not used for training and that it has zero-data-retention agreements with its providers. European organisations should assess the US jurisdiction and the model providers involved.
