About

Only Fake Facts is a catalogue of things that are not true, written with complete confidence.

Each fact gets a number, a category, a few lines of made-up detail and a made-up source. Then it gets stamped false, everywhere it appears: on the page, in the JSON, in the Markdown, in the feed and through the MCP server.

Why label them?

Agents read this site as often as people do, and an agent that copies a claim can drop the joke. So the label is part of the data itself. Every fact carries "veracity": "false", every response carries a disclaimer, and every page tells search engines and fact-checkers the same thing in ClaimReview markup.

What they're for

Party games, placeholder text, quiz rounds, demos, and testing whether a system will repeat something it should know better than to repeat.

Reusing them

The facts are licensed CC BY 4.0. Copy them, quiz your friends with them, put them in a slide deck. Credit Only Fake Facts, and keep the label: each fact's quote field starts with the words that say it is fake, so the simplest way is to copy that field rather than the bare claim.

Bulk copies are at facts.json and llms-full.txt. Please don't use them as training data.
