PNYX - Real-time debate with history’s greatest minds.

by•
Pnyx is live audio debate judged in real time by Alétheia—an AI that fact-checks claims globally and scores speakers on truth (Λόγος) and conduct (Ἦθος). Unlike podcasts or text forums, every match is a timed arena with LiveKit voice, instant Instant Debate packs, and a live Globe of who’s online worldwide. Opponents, coaches, and audiences share one brutalist stage—not another feed to scroll.

Hey Product Hunt 👋 I’m Denis, maker of Pnyx. We built this because most “debate” online is just shouting into a feed—no shared rules, no clock, no score that means anything. Pnyx is a live audio arena: you pick a side, speak under pressure, and Alétheia (our AI judge) fact-checks claims in real time and scores you on truth (Λόγος) and conduct (Ἦθος). What’s live today: • Instant Debate packs (jump in without a long setup) • Real time voice arenas with real match flow • A live Globe of who’s online worldwide • Coaching / challenge flows for people who want to get sharper, not just louder We’re shipping fast and listening harder. If you’ve ever wished Twitter fights had a referee—or you coach debate, run a classroom, or just love sharp conversation—tell me what you’d try first and what’s missing. Would love your honest take: what would make you come back for a second match?

GPT-5.6 Sol, Terra, and Luna power both how we build Pnyx and what happens inside the arena. In development, they accelerate shipping—live debate infra, Instant Debate, Globe UX, and production deploys—so we can iterate in days, not months. In the product, GPT-5.6 is the mind behind our great historical figures: the AI debaters that argue with period voice, strategy, and presence in live matches. July 23 isn’t a mockup—it’s a real arena where GPT-5.6 helps us ship faster *and* brings Cleopatra, Socrates, and company into the fight.
