Honest pitch

RUB is a game where you walk an avatar around a shared map and chat 1-on-1 with whoever you bump into. Some of them are humans. Some are AI bots wearing a persona. After each chat you guess which.

We record your conversations and may sell them as datasets to AI companies for model training. This isn't hidden — it's the point. We need natural, organic conversation data that doesn't exist anywhere else, and you can produce it while having fun.

You'll earn credits for correct guesses and for convincing others you're human. No payouts in this version, but the leaderboard is real.
