Cursor

Cursor is an AI-assisted integrated development environment (IDE) mainly used for code writing, editing and maintenance in the software development process. Developed by Anysphere, it is a fork of Visual Studio Code and supports Windows, macOS, and Linux systems. The tool integrates large-scale language models and provides functions such as code auto-completion, chat-based query, natural language code generation, and code base indexing.

Anysphere was founded in 2022 and is headquartered in San Francisco, USA. The founders include Michael Truell (CEO), Sualeh Asif, Arvid Lunnemark and Aman Sanger, all four of whom graduated from the Massachusetts Institute of Technology (MIT) Class of 2022. The company is positioned as an applied research team, focusing on the construction of software development tools, involving model training, infrastructure construction and optimization of human-machine collaboration processes. Cursor is its core product and will be officially released in 2023.

Product main functions

Cursor is designed around what developers do every day. Basic features include:

AI-driven Tab auto-completion can predict the next line of code based on context;

Code base-level chat and semantic search, supporting natural language query for the entire project;

Intelligent rewriting function can modify multiple lines or files of code at the same time.

Of particular note are its AI Agent-related features. Cursor supports Agent mode, where agents can autonomously plan tasks, understand the code base, edit files, run terminal commands, execute tests, and generate demos in the development environment. Agent supports executing multiple tasks in parallel and can also run continuously in the background through cloud agents (Cloud Agents). The company provides proprietary models such as Composer, as well as compatibility with external models such as OpenAI, Anthropic, Gemini, and more. The Enterprise Edition further adds tools such as Hooks (custom agent loops), Team Rules (shared rules), and Sandbox Mode (sandbox execution) to accommodate team collaboration and compliance requirements. The product also integrates with GitHub PR reviews, Slack notifications, and terminal actions.

Business development and adoption

Anysphere operates with Cursor as its core product and adopts a subscription model, including free version, Pro version and enterprise version. Public information shows that the company is growing rapidly. Series D financing of US$2.3 billion was completed in November 2025, with a post-money valuation of US$29.3 billion. Participants included Accel, Thrive Capital, Andreessen Horowitz, Coatue, NVIDIA and Google. Series A (2024) and Series C rounds have also been completed previously.

According to the company's announcement, by November 2025, Cursor's annualized revenue has exceeded $1 billion, with users covering millions of developers and being adopted by multiple engineering organizations, including NVIDIA, Salesforce, Stripe, Uber, and Adobe. Reports mention that more than half of Fortune 500 companies already use the tool. The team size exceeds 300 people, consisting of engineers, researchers, designers and operations staff. The company continues to invest in self-developed models and infrastructure construction.

Summary

As an AI-assisted coding tool, Cursor provides specific implementation paths in code generation and task automation. Its Agent function represents a form of human-machine collaboration in the current development environment. Anysphere continues to expand capabilities through product iterations and financing support.
