// about GPT Engineer
GPT Engineer (now Lovable's predecessor, continuing as gptengineer.app) was one of the first tools to demonstrate AI generating a complete, runnable codebase from a single natural language specification. The user describes what they want to build, the AI asks clarifying questions, then generates all the files and code needed. Its open-source roots spawned a large community and influenced a generation of AI coding tools. The project continues as a web app and CLI tool for developers who prefer a more raw, configuration-driven approach to AI-generated projects.
