What is WebSim?

WebSim is an AI-powered platform that creates complete interactive websites, games, and web applications from simple text prompts or URLs. Founded in 2024 by Rob Haisfield (COO) and Sean Lee (CEO) for the Mistral AI Hackathon (March 2024), publicly launched April 1, 2024.

"An entire fake internet powered by AI" - the platform simulates and generates fully functional websites (HTML, CSS, JavaScript) using Claude Sonnet 3.5 (originally Opus 3).

WebSim is NOT a traditional website builder - it's an "AI playground", "internet simulator", and "creative exploration tool" that can create from scratch any web concept you imagine.
