Ask every AI at once. Get one answer you can trust.
Quorum submits your question, in parallel, to OpenAI, Claude, Gemini, Grok, and Perplexity — using your own API keys — then cross-checks every answer into one consolidated, cited report.
- Your own API keys
- No account, no backend
- Runs survive restarts
/// The problem
Research-grade answers, one model at a time.
The best answers come from cross-checking several strong models — but doing that by hand means five prompts, five tabs, and no idea what any of it cost.
No cross-check
Ask one model and you get one view; the disagreements that reveal the truth stay hidden.
Cost is a mystery
Fire off a deep-research run and you find out what it cost only after the bill arrives.
Everything wants a backend
Most multi-model tools route your questions and keys through their servers — a trust problem for real work.
/// What Quorum does
Five research-grade AIs, one cited report.
Parallel answers, adjudicated into consensus, with every cent visible — straight from your Mac.
One question, five AIs
OpenAI, Claude, Gemini, Grok, and Perplexity answer in parallel — including their deep-research modes.
Consensus & conflicts
Agreement is measured, disputes are adjudicated with reasoning, and single-source claims are flagged.
Every cent visible
An estimate before, live spend during, and exact totals after — with per-run caps you set.
Your keys, zero cloud
No account and no backend; questions go straight from your Mac to the providers using your own API keys.
Runs survive restarts
Deep-research jobs continue in the menu bar and resume after you relaunch.
Cited, consolidated report
Every answer is cross-checked into one report you can actually rely on.

/// FAQ
Good questions.
Whose API keys does it use?
Your own. Quorum has no account and no backend — your questions go straight from your Mac to OpenAI, Claude, Gemini, Grok, and Perplexity using the keys you provide, and you pay those providers directly for usage.
Can I control what it spends?
Yes. You see an estimate before a run, live spend during, and exact totals after — plus per-run caps so a deep-research job can't surprise you.
Is it a subscription?
No. The app is a free download with three full runs included, then a single $19.99 one-time unlock on the Mac App Store — never a subscription.
