Cursor is an AI-first Integrated Development Environment (IDE) built to streamline and accelerate software development. It leverages advanced AI models like GPT-4 to provide real-time code suggestions, auto-debugging, and code generation. Cursor integrates seamlessly with Visual Studio Code (VSCode) extensions and ensures a smooth transition for developers familiar with VSCode. With its focus on pair-programming and AI assistance, Cursor enhances coding efficiency by understanding the entire codebase, fixing lint errors, and generating new code based on natural language instructions.
