AI Debate Platform

Let the experts
argue it out.

Expert AI advisors take opposed sides of your decision, research alone, then answer one another. You get one call — and the dissent beside it, so you know exactly where the argument split.

An example: the board’s call, and beside it who disagreed and why. The dissent stays on the memo, and the confidence drops because of it.

In short

What is an AI debate platform?

An AI debate platform is software that has multiple expert AI advisors argue a strategic question and produces one call that keeps the dissent — the arguments, the counter-arguments, and where the experts split, not just a final answer.

Debate is an old way to find out what holds. Courts, seminars and boardrooms all use it, because an argument that has survived a serious counter-argument is stronger than one that never met one. SynthBoard brings that to any call: bring the question, name anyone you want seated, and each expert researches alone, then answers the others.

The sides
On a decision, at least two experts are assigned opposed positions, and someone always argues against the obvious answer.
The argument
Each expert researches alone, then reacts once to the others. When one changes position, the memo says so.
What comes back
The call, how sure the board is (never above 90), who disagreed and why, and a first step with a date.
What it costs
A board on Free reads about 95 credits on its card. Each card shows what a room like it typically costs; you pay for what it really used.

Two arguments

Both sides, argued.
Then one call.

An open-source bet and a career change, each argued from opposed seats. In the first, one expert changes position after reading the others. Examples, trimmed for length.

Open-source the SDK?

Work · Board of 3

We’re 6 people at $30k MRR. Should we open-source our sync SDK before the Series A pitch in May, or keep it closed until we’ve raised?

Chief of staff

A real argument needs real sides. The Strategist argues for opening it, The CFO against, and The Engineer weighs what it costs to maintain in public. Each researches alone, then they react once to one another.

  • The CFOFinancial Controller
  • The EngineerTechnical Builder

Asked first

Who answers issues and pull requests if it goes public?

MeOne of the teamNobody yet

The board’s call

Open-source the SDK in April, under Apache 2.0, and keep the hosted sync service closed.

The CFO changed position after reading The Strategist’s research: three funded rivals already ship open SDKs, so a closed one has become the cost, not the moat. What stays closed is what customers pay for.

“Nobody owns the issues yet. A public repo with unanswered questions looks worse to investors than a closed one”

Retrain at 41?

Life · Board of 3

I’m 41 and have been an accountant for 15 years. A two-year nursing program starts in September and I have $38k saved. Do it, or stay put?

Chief of staff

Your board: The Skeptic argues against, The Empath argues for, and The CFO checks whether two years on $38k holds. Each researches alone, then they react to one another.

  • The SkepticRisk Assessor
  • The EmpathPeople Advocate
  • The CFOFinancial Controller

Asked first

Roughly what do you spend in a month?

Under $2,500$2,500–$3,500More than that

The board’s call

Apply for September, and keep ten hours a week of bookkeeping through the first year.

At about $2,700 a month, $38k lasts fourteen months. Ten hours of bookkeeping a week closes most of the rest — and the clinical placements, when the hours get hard to keep, only start in year two.

Confidence60 · Moderate

The Skeptic disagreed

“You haven’t worked a single shift on a ward. Volunteer for a month before you pay the deposit”

How the argument runs

Real sides, real reactions.
The dissent kept.

Sides assigned on purpose

On a decision, at least two experts are assigned opposed positions, and every board carries someone whose job is to argue against the obvious answer. The seats sit on different AI models.

A change of mind, on the record

Each expert researches alone, then reacts once to the others. When one changes position after reading the rest, the memo says so.

Then one step, with a date

An argument ends in one first step with a date. It waits under Open and gets one check-in on its day.

Bring the argument to your cofounder

The memo — the call, the arguments, who disagreed — shares as a read-only page anyone can open without an account, or exports as PDF or Markdown.

What people ask before their first argument.

What is an AI debate platform?

An AI debate platform has multiple expert AI advisors argue a strategic question. Each researches alone, then reacts once to the others. Instead of one reply, you see arguments, counter-arguments, and one call that keeps the dissent — so you know where the experts agreed and where they split.

Why is debate better than a single answer?

A single answer is only as good as the advisor giving it, and most advisors — human or AI — have blind spots. Putting experts on both sides surfaces the strongest counter-arguments alongside the strongest arguments, so you see the full landscape before you commit.

Can I pick the sides?

Yes. Name the advisors you want seated, and say in your ask which sides you want argued — the pivot, or staying the course. On a decision, the board assigns at least two advisors opposed positions anyway, and every board carries someone whose job is to argue against the obvious answer.

How is this different from ChatGPT pretending to argue with itself?

A single model running multiple personas still has one underlying set of biases and cannot genuinely disagree with itself. SynthBoard runs separate advisor instances with different roles and incentives, seated on different AI models — producing disagreement that is real, not staged.

What shapes the argument?

The question does. Your Chief of Staff proposes the board for the call in front of it, and you can name who sits. Each expert researches alone, then reacts once to the others. On a decision, at least two are assigned opposed positions, and the seats are spread across model families. When one changes position, the memo says so.

How long does it take?

The card shows the time before anything runs: about a minute for a consult, about 6–10 minutes for a board. You read the memo when it lands; nothing needs you to sit and watch. How many advisors sit depends on your plan.

How much does it cost?

Free to start — 150 credits every month + 250 to start. Talking to your Chief of Staff is free within a daily allowance. A consult or a board shows its price on the card before anything runs, and nothing runs until you tap.

Can I share what the experts said?

Yes. A board’s memo — the call, the arguments, the dissents, and next steps — shares as a page anyone can read without an account. Useful for aligning co-founders or briefing real advisors.
