It starts as chat. It escalates when it counts.
Decidi puts several frontier AI models and expert personas on one team to review, challenge and stress-test your work — grounded in live research from primary sources, then audits the verdict before you act. Here’s what happens in each step.
What is Decidi?
Decidi is AI chat that escalates. Everyday questions get an instant free answer. When something real is at stake, it brings in named specialist minds, has rival frontier models argue it out, and returns one audited verdict that names what still needs checking.
Start talking
You type. Decidi answers, reads what you attach, and keeps the thread — free, with no account and nothing to set up. Most questions end here, which is the point: the rest of this page is for the ones that should not.
It knows when to bring in specialists
A Concierge reads the conversation and stays quiet until something is genuinely at stake — real money, a contract, a launch, a call you cannot take back. Then it offers the right rung under the reply: one named specialist from 92, a panel of two or three cross-examining, the full Multi-Agent Team, or a working team that divides the job. What it draws on your plan, and how long it takes, are on the card before anything runs.
Rivals argue it out, on today’s facts
Decidi researches the facts the decision turns on — current laws, rates, prices, versions — from primary sources on the live web, and the verdict cites them. The team runs in parallel rounds: the minds state a position, read and rebut each other, and a Devil’s Advocate attacks the conclusion. A model asked to check itself hands back a rephrasing of its own answer; three rivals from three other labs do not.
The Chair synthesises — an independent sign-off decides
An impartial Chair, who took no side in the debate, synthesises it into one verdict — then a separate, proprietary Final QA audit reviews that verdict against known AI failure modes (hallucinated facts, weak reasoning, missed caveats), corrects what it catches, and signs off the final deliverable. On Quick and Deep runs the sign-off comes from a different house than the Chair; on Standard both are Claude, and the audit is a separate pass rather than a separate vendor. We say which, rather than implying it is always independent. Nothing is hidden: you see what was caught alongside the verdict.
You get a decision you can use
The result is a polished, downloadable deliverable — an audit, a decision memo, a redline, a rewrite — not a chat log. Ask for it built out and you get the finished Word, Excel, PowerPoint or PDF file itself. It is never a dead end: when the answer is “no”, it still hands you the corrected version or the exact next step. Every escalation shows what it draws on your plan and how long it takes before it runs, and every run is saved to reopen.
Watch one decision go through it
An illustration of the flow — not a real customer’s decision.The conversation turns to a build-vs-buy call, so Decidi offers the minds worth having on it — a CTO for feasibility, a CFO for the true cost, a Pragmatist for time-to-value and a Devil’s Advocate to attack the popular answer — each running on a different frontier model. You see who is on it, and what it draws on your plan, before anything runs.
Decidi pulls the current pricing, limits and fees of the actual billing providers — the numbers most estimates hand-wave — from their live docs and cites them, so the comparison runs on today’s figures, not a guess.
The CTO argues in-house gives control; the CFO prices the maintenance cost most estimates ignore; the Devil’s Advocate attacks the “we’ll customise it later” assumption. Two models lean build, one leans buy — the disagreement is shown, not averaged away.
The moderator’s first draft leans “build”. Final QA flags that it never costed the engineering time against the roadmap it would displace — and holds the verdict until that trade-off is on the page.
Buy now, revisit at scale — with the break-even volume named, the single assumption that would flip the call, and a “verify before you rely on this” list. A decision you can defend, not a confident guess.
What Decidi takes on
Anything where being wrong is expensive — from the first question to the finished document.
The part that makes it trustworthy: a proprietary Final QA audit reviews every verdict against known AI failure modes and attaches every flag it finds, in the open — so you act on a result that’s been checked, not just generated. See the Trust Stack →
And when you need the finished file, not just the verdict: “Build it out” takes the design the team agreed on and produces the actual artifact in full — a document, dataset, web page, code or content, a real Word, Excel or PDF file, even an image or a short video. Attach what you’re working from — Word, Excel, PowerPoint, PDF or an image — and it reads it first. The work itself, ready to download, not a description of it. How build-out works →
What makes a deliverable decision-ready?
“Decision-ready” isn’t a slogan — it’s a fixed standard every verdict is held to before it reaches you. A single chatbot hands you a confident paragraph. A Decidi verdict is built to be acted on, and the Final QA checks it against these gates — flagging anything that falls short, in the open:
And if a decision genuinely can’t be made responsibly yet — a critical input is missing, or the stakes need a qualified professional — the team says so plainly instead of faking certainty. That refusal is part of the standard too.
Common questions
What is Decidi?
Decidi is AI chat that escalates. Everyday questions get an instant free answer. When something real is at stake — a contract, a launch, an investment, a plan you are about to act on — it brings in named specialist minds, has rival frontier models argue it out, and returns one audited verdict with the open questions named.
How does Decidi work?
You start in chat — free, no account. When the stakes warrant it Decidi offers the specialists, and a Multi-Agent Team of expert personas assembles inside the same thread, each mind running on a different frontier model. Decidi grounds the decision in live research — pulling the facts it turns on from primary sources and citing them — then the team debates it across rounds, an impartial moderator synthesises a verdict, and a proprietary Final QA audit reviews that verdict for hallucinations and weak reasoning before it is finalised. You get a downloadable deliverable — and when the answer is “no”, it still hands you the fixed version or the next step to use.
Why use multiple AI models instead of one?
A single model inherits its own blind spots and biases, tends to agree with your framing, and cannot reliably catch its own mistakes. Running several independent models that challenge each other surfaces disagreement and error that one model alone would miss.
What happens when the AI models disagree?
Disagreement is the point. Decidi shows you exactly where the models diverge, then the moderator weighs the arguments and gives a reasoned verdict — and the Final QA audit flags anything still unresolved for your sign-off, rather than papering over it.
What makes a Decidi deliverable “decision-ready”?
Every verdict is held to a fixed standard before the Final QA signs it off: it leads with the answer and a confidence level, grounds each conclusion in your specifics with the working shown, names the load-bearing assumptions, surfaces the strongest dissent, ranks the risks by severity, says what not to do, and ends with a “verify before you rely on this” list. It never fabricates a citation, statute or number — unknowns are flagged, not guessed. And if a decision genuinely cannot be made responsibly without more input or a professional, the team says so rather than faking certainty.
Can Decidi produce the finished file, not just feedback?
Yes. “Build it out” takes the design the team agreed on and produces the actual finished artifact — every item in full, ready to download. That can be a document, dataset, web page, code or content; a real Word (.docx), Excel (.xlsx) or PDF file; or even an image or a short video. You can also attach what you’re working from — Word, Excel, PowerPoint, PDF or an image — and it reads it first. You get the work, not a description of it.
Is Decidi a replacement for professional advice?
No. Decidi makes AI output trustworthy enough to act on and catches problems before you ship, but it is not legal, financial or other regulated professional advice. For decisions that genuinely require a licensed professional, it tells you so.
