The Slop Tells Checklist - Spot AI-written text in 60 seconds

AI writing leaves fingerprints: the hedge words, the rule-of-three lists, the "it's not just X, it's Y" cadence, the confident filler. Slop Tells is a free one-page checklist of the tells that give it away, so you can catch AI slop in your own drafts before you send them and in anyone else's before you trust them. No signup wall, no tool to learn. Read it once and you will never unsee the patterns.
