Don't trust one AI with an important decision.

Quorum asks multiple AI models at once, compares their answers, and gives you a clear verdict: what they agree on, where they disagree, and what you should verify.

Ask once. Hear from the whole committee.

Real questions, the way Quorum answers them.

Which bank would offer me the best mortgage rate in Austin?
GPT-5.5 agrees

Likely a local credit union — UFCU or Amplify routinely beat the big banks by 0.3–0.5%. Get quotes from at least three lenders.

Claude Opus 4.8 agrees

Rates move daily — compare UFCU, Frost Bank, and one online lender. Judge the full APR with fees, not the headline rate.

Gemini 3.5 adds nuance

Searched current listings: Austin credit unions average ~0.4% under national banks today, but online lenders can match them with faster closing.

⚖️ Committee Ruling Confidence: High

Start with Austin credit unions (UFCU, Amplify) — all three members agree they beat national banks. Compare at least three full-APR quotes.

Dissent: [Gemini] notes online lenders can match credit-union rates with faster closing. Verify: posted rates the day you lock.

Which 3-row SUV under $40k is the most reliable for a family of five?
GPT-5.5 agrees

Kia Telluride for space and value, or a lightly used Toyota Highlander if long-term reliability is the top priority.

Claude Opus 4.8 agrees

Reliability data puts the Highlander and Honda Pilot on top; the Telluride wins on space per dollar and warranty length.

Grok 4.3 disagrees

Telluride, no contest — best third row in class. But budget for insurance: it runs noticeably higher than Toyota's.

⚖️ Committee Ruling Confidence: High

Shortlist the Kia Telluride and Toyota Highlander. Telluride if space and warranty matter most; Highlander (new or 2-year used) for the strongest reliability record.

Dissent: [Grok] would skip the Toyota entirely. Watch out: [Grok] flags higher insurance premiums on the Telluride — get a quote before deciding.

Is $165k base fair for a senior engineer offer in Denver?
GPT-5.5 adds nuance

Slightly below market — Denver senior medians run $170–185k. There's room to negotiate base or equity.

Claude Opus 4.8 agrees

Fair but not great. Total comp matters more than base — ask about bonus and equity before countering on salary alone.

Gemini 3.5 agrees

Current salary data shows $160–190k for senior engineers in Denver. $165k is in range but below the midpoint.

⚖️ Committee Ruling Confidence: Medium-High

In range, but below midpoint — negotiate. All members agree a $10–15k counter is reasonable; ask for the full comp breakdown first.

Consensus: counter with data, not ultimatums. Verify: the equity vesting schedule before comparing offers.

🤯

You compare them manually?

Every AI has blind spots.
You deserve the full picture.

One model hallucinates. Another misses the tradeoff. A third sounds confident while being dead wrong.

When it matters, you end up juggling tabs, copy-pasting prompts, and deciding who to trust with zero structure.

Quorum replaces the tab dance with a committee.

Three ways to read the room

Choose how your committee reaches its verdict.

GPT

Gemini

CONSENSUS

All models answer independently. The aggregator tallies their positions and delivers a majority ruling. Fast, cheap, one round.

Best for: quick decisions

Get a fast poll of the room. Perfect for factual questions, sanity checks, and "should I do X?" moments.

Round 1 → Round 2 → Revised positions
REVISED

Models answer, then read each other's positions and revise. Watch opinions converge — or sharpen. Multi-round, higher quality, ~2x cost.

Best for: complex decisions

Strategy calls, architecture reviews, nuanced tradeoffs. Let the committee actually debate before ruling.

QUALIFIED

All models answer in parallel. The aggregator picks the most qualified, well-evidenced response as the ruling and uses the rest to verify its correctness.

Best for: expert questions

Technical, medical, legal — when you want the best answer validated by peers, not a majority vote.

Why BYOK beats subscriptions

Most people use 5-7 prompts/day. With Quorum querying 3-4 models per prompt, here's what that actually costs with your own API keys:

Budget models

~$2/mo

Gemini Flash + Groq + Haiku

Mid-tier models

~$8/mo

Sonnet 4.6 + GPT-5.4 + Grok 4.1

Premium flagships

~$22/mo

Opus 4.8 + GPT-5.5 + Grok 4.3

Compare that to subscriptions:

ChatGPT Plus$20/mo - 1 provider Claude Pro$20/mo - 1 provider Gemini Advanced$20/mo - 1 provider Grok Premium$30/mo - 1 provider All four combined$90/mo

With Quorum + BYOK you get all providers in one app for a fraction of the cost — and you only pay for what you use.

Questions? Answered.

Yes — app.aiquorum.app is the free browser version with the full committee experience. All three agreement modes, role assignment, web search, and extended thinking work exactly as they do in the native app. Conversations are saved in your browser's local storage. The native iOS & macOS app adds iCloud sync, native notifications, and Keychain key storage for $14.99 one-time.
API keys let you connect directly to AI providers (OpenAI, Anthropic, Google, etc.). Each provider has a free or pay-as-you-go developer console where you generate a key in seconds. Quorum stores them securely in your device's Keychain — we never see or transmit them.
For typical use (5-7 prompts/day across 3-4 models), expect $2-$8/month with mid-tier models. That's a fraction of what a single $20/mo subscription costs — and you get access to every provider simultaneously. You only pay for tokens you actually use.
No. Quorum is a one-time $14.99 purchase. No subscription, no usage fees from us, no upsells. You pay the AI providers directly for the tokens you consume — that's the only ongoing cost, and it's typically under $10/month.
OpenAI (GPT-5.5, GPT-5.4), Anthropic (Claude Opus 4.8, Sonnet 4.6, Haiku 4.5), Google Gemini (3.5 Flash, 3.1 Pro), Groq (GPT-OSS, Llama, Qwen), and xAI (Grok 4.3). We add new models as they ship — no app update required for most additions.
Democratic: all models answer once, aggregator tallies consensus. Fast and cheap. Deliberative: multi-round — models read each other's answers and revise. Higher quality, ~2x cost. Evidence-Based: aggregator picks the most qualified response and uses others to verify it. Best for expert questions.
Never. Your prompts go directly from your device to each AI provider's API. Quorum has no server, no analytics on your content, and no way to read your conversations. History syncs via your personal iCloud account only.
Yes — Quorum is a universal app. Buy once, use on all your Apple devices. Conversations sync across devices via iCloud automatically.
