Slop or Not

Slop or Not is a free browser game from Ellora that tests whether you can tell human writing from AI writing. You read nine short pieces over three rounds, from support chats to sales lines and outbound emails. For each one you call Slop or Not slop, by click or with the S and N keys. After each pick the game shows what gave the text away, such as stock openers, hedge stacks and inflated words. It takes about two minutes and needs no sign-up. At the end you can copy your score, share it on X or LinkedIn, or challenge someone.
