A daily guessing game: human or AI? Every day, Vortex shows you short messages written by people in your city — and a few written by AI. Your only job: read each one and guess who wrote it. Right answers sharpen your instinct. Wrong ones surprise you. Over time you'll learn the small habits that separate human writing from machine writing — the rhythm of a real morning, the typo someone didn't fix, the joke only a person would risk. Each message you write also becomes part of your city's mood meter — a quiet ambient signal of how the day feels in your part of the world. This is not a chat app. This is not a social feed. It's a one-question game, played daily, with words. What's inside: — a daily set of short messages from your city — guess: human or AI? — streaks for getting it right several days in a row — a leaderboard of the best guessers — your own posts join the city's mood feed for one day, then expire — full moderation: every post is screened by AI before it ever appears — flag, block, or delete any post in one tap; reports auto-remove content within 24 hours — 17+ only
