Decidi vs. Roundtable AI
Thirteen models answering together, or a debate that ends in an audited verdict.
Decidi vs. Roundtable AI: the short answer
Roundtable AI (round-table.ai) puts your question to 13 models across four providers — Claude, ChatGPT, Grok and Gemini — in one conversation, so you can compare where they agree and disagree before you decide; its own line is that it is built for questions that need right answers. Decidi shares that conviction and finishes the job differently: the models don't just answer together, they debate across structured rounds with 92 expert personas and a Devil's Advocate, a moderator synthesises one verdict, and a Final QA audit on a model from a different lab reviews it before it lands as a downloadable deliverable. The door differs too: Roundtable AI's published plans start at $30/month; Decidi starts in free chat with no account, and the full Multi-Agent run is included in Plus at $19/month.
What Roundtable AI does well
Roundtable AI is a focused, quality-first take on multi-model work: 13 current models across the four frontier providers in one conversation, built specifically for high-stakes questions rather than novelty, with straightforward plans. If you want several strong models answering together in one thread — and you’re happy being the judge of the result — it does that well.
Where Decidi is different
Several answers in one thread still leave the reconciling with you: you read where the models agree and disagree, and you make the call. Decidi does the reconciling as part of the run — rebuttal rounds, a Devil’s Advocate attacking the emerging answer, a moderator verdict — and then has that verdict reviewed by a Final QA audit at a separate lab before you see it, delivered as a document you can sign off. And where Roundtable AI’s published plans start at $30/month, Decidi lets you start for nothing: free chat with no account, every reply stamped with the model that wrote it, and your first full run included with a free signup.
The difference that matters most: an always-on Final QA audit reviews every verdict against known AI failure modes before it’s final — so you act on a result that’s been checked, not just generated. See the Trust Stack →
Questions
Is Decidi an alternative to Roundtable AI?
If what you want is several frontier models answering in one conversation with you as the judge, Roundtable AI does that job well. Decidi is the alternative when you want the judging done inside the run: a structured debate, a moderator verdict, a Final QA audit from a lab that didn’t chair the debate, and a downloadable deliverable — with a free way in to see it working before any plan.
