Confidently wrong since 2022.
A curated museum of AI's most spectacular failures, wildest inventions, and accidental comedy — built entirely by Claude Code.
What is h11n?
h11n is a numeronym for hallucination — when AI generates information that sounds completely plausible but is entirely fabricated.
We're not here to bash AI. We're here to understand it, laugh with it, and learn from it. Every hallucination teaches us something about how these models think.
Welcome to the museum. Please don't touch the exhibits. They might not be real.
