Why a text game?
SI (AI) models can now write in almost any voice: a wire report, a grumpy letter, a chatty travel tip, even a Victorian diary. Playing a few rounds shows you how little a single paragraph gives away, and how often perfectly ordinary human writing "sounds" generated. Read our guide on how to spot SI text first if you want an edge, then paste anything you are unsure about into the SI text detector. Prefer pictures? Play the image game.
Every human text in the bank was written by people and published under a free licence or in the public domain, and is credited below. Every SI text was generated for this game and is labelled as such.
Text credits
Human texts are short excerpts, cut at sentence boundaries, from older revisions of Wikipedia, Wikinews, Wikibooks and Wikivoyage articles (written before SI writing tools became common) and from public domain books on Project Gutenberg. Each answer in the game links to the exact source. SI texts were generated for this game by Claude and Grok.
