WebSim

WebSim is an experimental and highly creative AI platform that uses large language models to simulate the entire internet, allowing users to "browse" and interact with websites, games, and applications that don't actually exist.

Key Features

Prompt-to-Website Simulation: Type a URL or a description of a website you want to visit, and WebSim will generate a fully interactive, functional HTML/CSS/JS interface in real-time.
Interactive Apps and Games: Capable of generating playable web games, interactive tools, and complex UI layouts entirely from a single prompt.
Remixing and Iteration: Users can "view source," modify the prompt, and continuously iterate on the generated applications.
Fictional Internet: Users can explore a surreal, simulated web where links navigate to other hallucinated, AI-generated pages.

Target Audience

Creative technologists and designers prototyping wild UI/UX concepts instantly.
Gamers and hobbyists exploring AI-generated interactive fiction and mini-games.
Developers looking for rapid inspiration or functional HTML/CSS snippets for specific UI components.

How it compares to alternatives

Unlike v0.dev or Lovable, which are serious tools designed to output production-ready code for developers, WebSim is positioned more as a creative sandbox and a demonstration of LLM hallucination as a feature. It focuses on the experience of "browsing" an infinite, simulated web rather than exporting a clean React codebase for deployment.
