Thesis

A council of brilliant minds debating your decision.

Agents that don't just answer you: they challenge each other and surface your blind spots.

01
The problem

Making good decisions alone is hard: we lack perspectives and fall into blind spots.

Inspired by a practice described by Napoleon Hill, Roundtable seats you with a personal council of thinkers —represented by AI agents— who debate your dilemma from different mental frameworks.

02
Tech stack

A fast SPA for a fluid, reload-free debate experience.

Orchestrates the multi-agent conversation and the live debate state.

Typed agents, turns and messages to keep the debate coherent.

An interface focused on reading the debate, with no visual noise.

Each thinker is an agent with its own mental models; I orchestrate a debate that challenges itself.

Product analytics to understand how debates are used and improve the experience.

Architecture

A Vite + React SPA that orchestrates several OpenAI agents in a moderated debate; each agent reasons with its own mental models and reacts to the others. PostHog provides product analytics on real usage.

Learnings
Building Roundtable taught me to design multi-agent systems where the value isn't a single answer but the contrast of perspectives. Orchestrating agents that challenge each other —and keeping the debate focused on the decision— is as much a design problem as a prompting one.
