Pricing
A fixed price per debate, known before it starts
Host it yourself for free, or use our cloud version, with the cost of the AI models included. Each debate has a fixed price, charged once, when it starts.
Pay for each debate
Available nowBuy credits in packs from €10, and each debate is paid from them. Credits alone are for one person; to work as a team, choose the Team or Agency plan. The interview is included in the debate's price: if you stop after it, you pay nothing, unless it ran unusually long.
Express
€3 per debate
A quick opinion
- A few questions and one short round
- A clear recommendation in minutes
Standard
€7 per debate
Compare solutions, challenge your idea or audit a document
- Two to four AIs and an independent arbiter
- The full decision report
Deep
€15 per debate
For high-stakes decisions: compare, challenge or audit in more depth
- The models reason more deeply, with more web searches
- On a monthly plan, uses 2 of your included debates
With a Premium model (Claude Fable 5.1, GPT-6 Astra), a debate costs twice as much: €6, €14 or €30.
Got new answers from your client? The arbiter updates its recommendation with them, without a new debate. A recommendation update costs €1, paid from your credits, never from your plan's included debates. If it fails, you pay nothing.

Cost
What a debate costs, and why it never costs more
Every debate has a running cost: AI providers charge for the text their models read and write. In the cloud, you pay the debate's fixed price and never more: we stop the models before they cost more than that price covers. Self-hosted, the app shows the cost of each role as it runs and stops at the limit you set.
FAQ
Questions and answers
How much does Quorumind cost?
With the hosted version, each debate has a fixed price, AI models included, shown before it starts: €3 for Express, €7 for Standard (compare solutions, challenge an idea or audit a document) and €15 for Deep. A debate with a Premium model costs twice as much. Credit packs start at €10. Monthly plans include a number of debates every month, Express, Standard or Deep: a Deep debate uses 2 of them, and a Premium debate twice as many. Solo costs €49 a month for 6 debates and one person, Team €199 for 25 debates and up to 5 people, Agency €499 for 60 debates and any number of people. Self-hosted, you pay your AI provider directly for what your debates use, under a cap you set, or nothing with models running on your own machine.
Which AI models can I use?
With the hosted version: Claude Opus, Sonnet and Haiku, GPT-6.1, Gemini and Mistral models, included in the price, and as a Premium option the most powerful ones, Claude Fable 5.1 and GPT-6 Astra, which double the price of a debate. They are reached through OpenRouter: you need no account with these companies. Self-hosted, the providers you connect with your own accounts, and local models through Ollama. You choose the model for each role: interviewer, debaters, devil's advocate and arbiter, and you can mix models from different companies.
Is Quorumind free, and can I host it myself?
The self-hosted version is free and open source, under the AGPL v3: you install it on your own server with Docker and pay your AI provider directly for what your debates use, or nothing with models running on your own machine. The cloud version is paid. Either buy prepaid credits and pay a fixed price for each debate, for one person, or choose a monthly plan with debates included: Solo for one person, Team or Agency for a whole team.
How do I cancel a plan?
A plan renews every month until it is cancelled. An owner or an admin of the workspace cancels it at any time from the Billing page, through the “Invoices and payment methods” link, which opens Stripe's customer portal. The cancellation takes effect at the end of the month you have paid for, and the plan stays usable until then; that month is not refunded. Credits, for their part, never expire.
