The agents do the work. Their rivals check it.
Decidi is free AI chat that escalates. When the call actually matters, a Multi-Agent Team of specialist minds takes the work and rival frontier models argue the answer out — then a separate audit signs off one verdict and names what still needs checking. Drift and invention don’t survive the room.
Four rival minds.
One verdict.
Your Multi-Agent Team is OpenAI, Anthropic, Google and xAI — four rival labs on the same piece of work. They review it, debate it, cross-check each other for the blind spot one model would miss, and return a verified verdict you can act on.
See how a run works
One model can be confidently wrong
Its training goes stale, its memory misremembers, its bias flatters — and it tells you with total confidence, right when your case, your raise or your name is on the line. The team cross-checks it against rival models and the source of truth, and catches what one AI would have let you walk into. Illustrative examples — the reasoning is real and checkable.
Drop it in. The right team takes it.
One tool per job — the minds already seated, your file in, the finished version back. Included with Plus.
Ask one model to check its own answer and you get that answer again, rephrased.
You don’t know what it missed, which assumption it skipped, or where its maker’s training left a blind spot. Decidi runs competing models from different labs against each other — so where one vendor is weak or biased, the others catch it. Independent minds, no single point of failure — before you commit.
“ChatGPT can make mistakes. Check important info.”
“Gemini can make mistakes, so double-check it”
“Claude can make mistakes. Please double-check responses.”
“Grok can make mistakes.”
Every lab prints the same warning under its own answers — then leaves the checking to you. Decidi is the check. See what they all admit →
We hold the work to the failure modes we catalogue in the AI Risk Library — each layer clears the ones in its remit, and anything that slips through is flagged to you, never shipped silently. An illustrative model of the process, not a measured catch rate.
Four steps to work you can trust
Free, and no account. Ask anything, paste your work, attach the contract or the deck.
When the stakes are real, Decidi names the specialists worth bringing in — from 86 expert minds — and shows what it draws on your plan before anything runs.
GPT, Claude, Gemini and Grok take the question from different sides. A model cannot wave through its own reasoning when three rivals are reading it.
A separate Final QA audit reviews the answer before you see it, then names exactly what you still need to verify.
Not a chat log — a deliverable you can act on
Every run ends in a verdict you can act on. Build it out then produces the thing itself — a designed document, a real Word, Excel or PDF file, an image or a short video.
Not yet — you’re about two weeks out. The product itself is strong, but the first-run experience won’t convert paid users. Launching now would spend scarce attention on a leaky funnel — clear the fixes below first (and open a private beta in the meantime).
- New users hit an empty state, not the value — high churn on day one.
- Pricing isn’t legible; “credits” read as friction at checkout.
- No trust/security page yet — enterprise and cautious buyers bounce.
- P0 — Redesign the empty/first-run state to show value immediately.
- P1 — Translate pricing into “what one decision costs”.
- P1 — Add a Security & Privacy page before paid launch.
- P2 — Instrument onboarding funnel; run 10 user tests.
“Two weeks of runway isn’t free. If the beta validates retention, launch on schedule and fix onboarding in-flight rather than slipping the date.”
One model vs. the team
- You ask one AI.
- It gives one confident answer.
- You don’t know what it missed.
- You paste into another model and compare by hand.
- You still have to decide alone.
- Multiple models respond — in their own voices.
- Expert minds challenge the assumptions.
- Risks and blind spots are surfaced.
- Trade-offs are ranked, dissent is shown.
- A moderator hands you one decision memo.

Common questions
What is a Multi-Agent Team?
A Multi-Agent Team is several independent frontier models — GPT, Claude, Gemini and Grok — each carrying a specialist persona, working the same question and reading each other’s reasoning. They disagree in the open, then a separate Final QA audit reviews the result. You get one cross-checked verdict instead of one model’s opinion. If you arrived looking for the Decidi council, this is it, under its plainer name.
What is Decidi?
Decidi is an 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 — Decidi puts a team of named specialist minds on it, has rival models argue it out, and returns one audited verdict with the open questions named.
How is Decidi different from ChatGPT or Claude?
ChatGPT and Claude are single models answering alone, and a model asked to check its own work tends to restate it rather than challenge it — a second opinion from the same mind is not a second opinion. Decidi starts as ordinary chat, then puts the important calls to rival models from different labs, so disagreement surfaces instead of staying hidden, and a separate audit signs the answer off.
How does Decidi stop AI hallucination and drift?
Three ways, and none of them is asking a model to grade itself. Rival models from different labs review the same work, so one model’s invention has to get past three others. Live web research grounds facts that change. And a proprietary Final QA audit reviews the verdict before you see it, then hands you a short “verify this” list — because the honest answer is that you should still check the load-bearing claims.
Is Decidi free?
Yes — chat is free and needs no account: 20 messages a day as a guest, 75 with a free account, plus one consultation with a named specialist on the house. Beyond that it is a monthly plan, counted in full runs rather than credits. Plus ($19 a month) gives you unlimited chat, unlimited specialist minds, panels and 15 full runs a month; Pro ($49) adds working teams, Deep depth and 50 runs a month. Cancel at any time.
