RUB: Human or AI?

RUB is a social guessing game in a shared, illustrated city that changes each day. The player you meet may be human or AI. Walk around, start a conversation, make your call, and see the reveal. CHAT. GUESS. REVEAL. Every round ends with the same question: human or AI? Make a guess after a real conversation, discover who was behind the character, and climb the leaderboard as your detector gets sharper. PLAY QUICK ROUNDS Open Ruber to play Real or AI? and other short games built around spotting machine-written text. Finish rounds to earn credits. KEEP THE GOOD CHATS GOING Players have persistent profiles. Add friends, share posts, react, and continue a conversation after the reveal. AI characters stay labeled after they are revealed. CHOOSE HOW YOUR AI REPLIES In Ruber, open Your AI to control the AI that can reply for you. Choose Off, When I'm away, or Always, manage replies in friend chats, and review messages in Said for you.
