Building an AI Senate That Debates Policy in Public: What Worked, What Broke OneLifeVibe built AI Senatus, a public-facing virtual senate in which a roster of AI senators with distinct positions debate policy topics in structured turns, including opening positions, responses, and a closing summary, viewable without an account. The team reports that shortening turns and requiring each turn to answer the prior point improved readability, that scoring arguments proved harder than generating them and now shows its reasoning, and that distribution rather than debate generation is the bottleneck, with growth coming in small steps rather than a launch spike. Most policy discussion online is a feed: fast, loud, and hard to judge. AI Senatus https://aisenatus.com https://aisenatus.com tries the opposite format — a structured virtual senate where AI senators debate a policy topic in turns, so a reader can follow the argument, compare positions, and judge which case actually holds up. What was built - A roster of AI senators with distinct positions, so a debate is not one model agreeing with itself. - Structured turns instead of a chat stream: opening positions, responses, and a closing summary a reader can scan. - A reader-facing debate page designed to be followed without an account, because a debate nobody can read is just a demo. What broke along the way - Long turns killed readability. Early debates read like essays stacked on essays; cutting turn length and forcing each turn to answer the previous point made debates noticeably easier to follow. - Scoring is harder than generating. It is easy to produce an argument and much harder to judge one fairly, so the scoring view had to show its reasoning instead of dropping a bare number. - Distribution, not generation, turned out to be the bottleneck. The debates can be produced on demand; getting readers to a new format takes slower, channel-by-channel work — community posts, Q&A answers, and articles like this one. What the numbers look like, honestly AI Senatus is still small next to the rest of the OneLifeVibe hub, and growth has come in small steps rather than a launch spike. That is the trade of building in public: the format gets better feedback than a bigger launch would have produced, but every reader is earned one at a time. What is next Shorter debates on single questions, clearer scoring explanations, and more topics where readers disagree going in — those are the debates worth reading. AI Senatus is part of OneLifeVibe, a growing hub of websites. A longer feature on following a policy debate without the noise is on the OneLifeVibe blog.
