Fresh human chat is the rarest data.

Models can ace the bar exam and still sound robotic and over-eager in open conversation. Closing that gap takes real people being real: on purpose, with consent. RUB mints that signal every day.


What the park produces.

EQ preference judgments

“Which reply is better?” verdicts on warmth, naturalness, and over-eagerness vs. genuine support, each with a written rationale. The lead signal.

Human-or-bot verdicts, with the tell

Live adversarial naturalness labels from real chats, plus what gave the bot away, in the player's own words.

Real multi-turn conversation

Consented human dialogue minted from play, not paid role-play. Fresh every day, scrubbed before export.

Rights-clean by construction.

Built so you can train on it and document it. Every row is something a player agreed to, and can walk back; the Privacy Policy is the canonical version of everything below.


Design partners

Want the sample before anyone else?

Private beta: we're after design partners, not customers yet. React to a real de-identified sample under NDA and tell us whether it clears your bar. The no is as useful as the yes.
