An AI App Builder is a platform that utilizes artificial intelligence to enable the rapid creation of mobile and web applications. By interpreting natural language inputs, these builders, powered by LLMs, can generate application structures, user interfaces, and backend logic automatically. Users can describe the app's features and target audience, and the AI translates these requirements into functional components. This approach democratizes app development, allowing non-developers to bring their ideas to life while enabling developers to prototype and build applications much faster than traditional methods.
