Stop trusting one AI. Important work needs a team.
One AI can be confidently wrong — and you’re left crafting prompts, hoping nothing slipped. Decidi hands your work to a council of frontier models that do it, challenge each other, and sign it off — ready to send, ship or sign.
A single AI answer will sound extremely confident when it’s wrong.
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.
We audit your work against 250 known AI failure modes — each layer crosses off 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
Type the call you’re weighing — or paste a brief and attach screenshots, decks or documents.
Auto-recommend a council for your decision, or hand-pick from 86 expert minds.
Choose how hard they should challenge it. Watch each mind think and rebut, live.
An impartial moderator delivers one decisive recommendation, with risks and next steps.
Not a chat log — a deliverable you can act on
Every council ends in a verdict you can act on — and Build it out produces the finished file itself: documents, real Word, Excel and PDF files, even images and 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. a council
- 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.
Never put your name on it untested
Before you file it, publish it, or ship it — let an independent council tear it apart, catch what one AI would hallucinate, and hand you the fixes. Pick your profession.
Find the hole in your argument before opposing counsel does.
Run the pre-mortem before reality runs it for you.
Kill the deal on paper before you wire the money.
Bulletproof the recommendation before the steering committee sees it.
Find the claim that gets you screenshotted before it ships.
Pressure-test the bet before engineering builds the wrong thing.
Survive the design crit before it’s in front of real users.
Get the staff-engineer code review before you open the PR.
Find the weak line before the client circles it in red.
Start from a proven brief
51 battle-tested debate briefs — each tells the council what to evaluate and what to deliver.
An exhaustive UX teardown of your app before you launch it.
A visual and UI teardown of your app — hierarchy, type, polish, dark mode.
Decide what to build next quarter and what to deliberately not build.
Design pricing, tiers and the value metric that scales with what you deliver.
Pressure-test a startup idea before you commit a year of your life.
Get your deck shredded the way a real partner meeting would.
Pressure-test a system design before you commit to it.
Align your money with your goals, time horizon and risk appetite.
Surface the clauses in an agreement that could hurt you later.
Real models. Shown openly.
Three levels, each a genuine mix of frontier models — never one model wearing different hats.
Fast, low-cost models — a lively first pass.
Proven pro models — the everyday default.
The newest, most capable models — for when being wrong is expensive.
Each mind in a council is assigned a different live model, round-robin across providers.
Every contribution is labelled with the model that produced it.
Cost is computed from real token usage with a transparent markup — shown before and during.
If a model is briefly unavailable, the council notes it and continues — never fakes a reply.

Common questions
What is an AI council?
An AI council is a panel of multiple frontier AI models — GPT, Claude, Gemini and Grok — plus expert personas that review your work together: they debate it, challenge each other, and a Final QA audit reviews the result. You get one cross-checked verdict instead of a single model’s opinion.
What is Decidi?
Decidi is a decision room where you submit important work — a contract, a pitch, code, a launch plan or a big decision — and a council of AI models debates it, then returns a clear, audited verdict plus a downloadable deliverable. It’s built for the moments when being right matters more than being fast.
How is Decidi different from ChatGPT?
ChatGPT is one excellent model answering on its own. Decidi runs several independent frontier models that challenge each other, adds a Devil’s Advocate, and reviews the verdict with a separate Final QA audit — so you see where the models agree and disagree and catch the blind spot a single model would miss. Use ChatGPT to create; use Decidi to review and decide.
Is Decidi free to try?
Yes. You get 3,000 free welcome credits to run a real council — no card required. After that it’s pay-as-you-go credits or an optional monthly plan, and credits never expire.
