An AI debate tool that argues both sides so you do not have to
The fastest way to test an idea is to watch it get attacked by someone competent. But a single chatbot will not truly argue against itself — it presents a balanced summary and moves on. Real debate, with a committed case for and against, is where weak ideas break and strong ones get sharper.
Decidi stages a genuine debate: different models and personas are assigned positions and argue them in structured rounds, rebutting each other directly. You watch the case for and against unfold, then an impartial moderator weighs the exchange and delivers the resolution.
- A committed case for and against, not a fence-sitting summary
- Multiple rounds of rebuttal that expose weak arguments
- The strongest objection to your idea, stated as well as anyone could
- Transparent reasoning you can follow argument by argument
- A moderator verdict that resolves the debate, not just restates it
- Adjustable depth for quick calls or high-stakes deliberation

Common questions
How is an AI debate better than a normal AI answer?
A normal answer hides the disagreement; a debate exposes it. When models commit to opposing positions and rebut each other, the weakest assumptions surface fast — and you end up with a sharper, stress-tested conclusion instead of a tidy but shallow summary.
Do the AIs really argue, or is it scripted?
They genuinely argue. Decidi assigns positions to different frontier models and personas and runs real rebuttal rounds, so each side is pressed to answer the other’s strongest points before the moderator weighs in.
Can I use it to prepare for a real debate or negotiation?
Yes. It is ideal for rehearsing the opposing case — you see the strongest arguments against your position in advance, so you walk into the room already knowing how to answer them.
