An AI Code Generator is a tool that uses artificial intelligence, particularly LLMs, to automatically produce source code from natural language descriptions, templates, or other inputs. It significantly speeds up the development process by handling repetitive coding tasks, scaffolding new projects, and generating boilerplate code. Developers can specify their requirements in plain English, and the AI will generate code in the desired programming language. This not only boosts productivity but also helps in learning new languages and frameworks by providing clear, functional code examples for a wide range of applications.
