Looking for a Suprmind alternative? Here is what to compare
Suprmind is one of the serious multi-model tools: five frontier models arguing in one thread, with disagreement treated as the point. If you are comparing alternatives, the useful questions are not about model counts — they are about what happens after the models argue. Who checks the verdict, and is the checker independent of the models that produced it? What do you walk away with — a thread to scroll, or a document you can act on? And what does it cost to find out whether the tool suits you?
Decidi answers those questions structurally. Four rival labs — OpenAI, Anthropic, Google and xAI — debate your question across structured rounds with 92 expert personas and a Devil's Advocate seated by design. After the moderator synthesises a verdict, a Final QA audit runs on a model from a different lab to the one that chaired, reviewing the result against known AI failure modes before you see it. The answer arrives as a downloadable, sign-off-ready deliverable. And the door is free: chat without an account or card, every reply stamped with the model that wrote it, and your first full Multi-Agent run included when you create a free account. After that, plans are priced in runs — Plus at $19/month includes 16 full runs a month.

Common questions
What should I look for in a Suprmind alternative?
Four things separate multi-model tools. First, whether the models genuinely debate — rebut each other across rounds — or just answer in parallel. Second, who verifies the result: a check inside the same pipeline, or an audit from a model independent of the ones that produced the answer. Third, the output: a conversation you interpret, or a deliverable you can act on and share. Fourth, the way in: whether you can see the product work before a trial or a plan. Decidi is built around all four — structured debate, a separate-lab Final QA audit, a downloadable deliverable, and a free chat front door.
How is Decidi different from Suprmind?
Both make frontier models argue rather than answer side by side — they are close cousins. The differences: Suprmind's dedicated Debate and Red Team modes start on its $45/month tier, per its published pricing, while Decidi includes the full adversarial run — Devil's Advocate included — in Plus at $19/month, with 16 full runs a month. After the debate, Decidi adds a Final QA audit from a lab that did not chair the run, and delivers a downloadable document rather than a thread. And Decidi's front door is free chat with no account, rather than a time-boxed trial.
Can I try Decidi without paying or signing up?
Yes. Chat is free with no account and no card — you pick the base model (GPT, Claude, Gemini or Grok) and every reply is stamped with the model that wrote it. From any reply, one tap hands the answer to a model from a rival lab to challenge. When you create a free account, your first full Multi-Agent run is included, so you can see a complete debate, audit and deliverable before deciding on a plan.
What does Decidi cost after the free run?
Plans are counted in runs, not tokens: Plus at $19/month includes 16 full Multi-Agent runs a month, and Pro at $49/month includes 44 plus working teams and Deep depth. Chat and specialist consultations are unlimited on both. The numbers are stated because a full multi-model debate has a real cost every time it runs — a plan that says "unlimited" is quietly rationing something.
