Roundtable: AI That Argues With You
AI Tooling / Vibe Coding
Built because I got tired of AI telling me I was right. I needed pushback — not praise. So I made AIs argue with each other instead.
Roundtable is a lightweight web app that simulates a team debate using AI. You ask a question. The app assigns roles (Product, Security, Dev, UX, etc.) to AI personas, each with clear motivations and constraints. Then they discuss — disagree, challenge, and pressure-test your idea like a real team would. No consensus required. Just clarity through conflict. Built in a weekend with Firebase Studio and vibe coding. Used it for design decisions, feature validation, and branding calls. Shared it with fellow designers — they called it “a team in my pocket.”
[Frustrations]
Every AI gave me polite, agreeable feedback — not the pushback I needed.
Getting real team input meant scheduling meetings, waiting days — if I could even get it.
As a solo designer, I kept missing blind spots in my own thinking.
[Goal]
Create a tool that surfaces disagreement — not just multiple answers, but real debate.
Simulate team dynamics without needing actual people or meetings.
Help solo creators stress-test ideas in minutes, not days.
I built Roundtable because every AI kept telling me I was right—and that wasn’t helping. I didn’t need validation; I needed someone to poke holes in my thinking. ChatGPT nodded. Claude praised. Gemini agreed. So I stopped asking for answers and started forcing a debate.
The fix wasn’t smarter AI—it was stronger roles. I gave each AI a clear job: a Product Lead obsessed with metrics, a Security Expert who kills ideas over privacy, a Developer who asks “How long will this take?” and a UX Researcher who quotes real user behavior, not opinions. They don’t just reply—they respond to each other. One says “Ship it!” The next says “Not with that data flow.” Suddenly, I’m seeing blind spots I’d never catch alone.
I built it in a weekend with Firebase and vibe coding—no over-engineering, just a clean chat-style interface. No prompts to write, no settings to tweak. Pick your roles, ask your question, hit go. It’s not about getting the “right” answer. It’s about seeing the problem from angles you’d naturally miss. And that’s why I—and other solo designers—keep coming back. Not because it’s flashy, but because it finally feels like having a real team in the room.
