Slop or Not is a free online game designed to assess a user's ability to distinguish between human written and AI generated text. It presents nine short texts sourced from customer support chats, marketing pages, and cold emails. Players must identify whether each text was written by a person or an AI. The game is structured in three rounds, covering customer support chat, marketing and sales copy, and outbound emails. The game requires no sign up and takes approximately 2 minutes to complete. It relies on JavaScript to function. Players score points for each correct identification. The texts include examples of common AI writing patterns, such as stock openers and closers, inflated words, and hedge stacks. These patterns are highlighted as indicators that can give away AI generated content. Typical use cases include testing personal awareness of AI writing styles or as a quick educational tool. The workflow involves starting with round one and progressing through all nine texts. The game is hosted on the Ellora website and is accessible directly through a web browser.
