Suprmind, Quorum AI Alternative

Most of it. Both platforms run structured multi-model deliberation with critique and synthesis — Quorum AI ships seven academically named methods (Standard, Oxford, Advocate, Socratic, Delphi, Brainstorm, Tradeoff) and Suprmind ships six modes (Sequential, Super Mind, Debate, Red Team, First Principles, Research Symphony). The patterns overlap closely: Quorum AI’s Standard maps to Super Mind, Oxford maps to Debate, Advocate maps to Red Team. Quorum AI’s Delphi (anonymous rounds for anti-anchoring) and Tradeoff (weighted multi-criteria scoring) are methods Suprmind doesn’t ship as named modes. Suprmind’s Sequential, First Principles, and Research Symphony cover ground Quorum AI doesn’t.

Both ship formal debate as a first-class capability. Quorum AI’s Oxford method runs structured proposition and opposition with rebuttals between models. Suprmind’s Debate mode supports three formats (Oxford, Parliamentary, Lincoln-Douglas), preserves minority opinions in the transcript, and produces an auditable record of the argumentation. Same intent, different implementations: Quorum AI focuses on the academic Oxford pattern as the canonical debate; Suprmind exposes three named formats and adds DCI tracking that quantifies disagreement across the rounds.

Quorum AI is a hosted web platform with managed API keys on paid tiers; conversation history retention is around 30 days on the free Observer tier and unlimited on Member ($9) and Delegate ($19). The open-source quorum-cli stores sessions locally under ~/.quorum/ for users who self-host. Suprmind is a managed platform with EU and Switzerland data residency by default — application in Germany, primary database in Switzerland, with DPA and MSA available on request. Different storage architectures, with both supporting persistent project containers (Quorum AI: Dossiers; Suprmind: Projects).

Quorum AI’s Voice Registry has up to 10 voices: 6 Commons models (GPT-5 Nano and Mini, Claude Haiku 4.5 and Sonnet 4.5, Gemini 3 Flash, Grok 4.1 Fast) on Member, plus 4 Inner Circle flagships (GPT-5.2, Claude Opus 4.5, Gemini 3 Pro, Grok 4) on Delegate. Suprmind runs five frontier models together on Pro and above (GPT, Claude, Gemini, Grok, Perplexity Sonar) with managed allocation included; Enterprise adds BYOK across all five providers with dedicated workspaces. Quorum AI gives you tier-gated breadth across mid and flagship variants; Suprmind always gives you all five frontier flagships in every conversation on Pro+.

Yes at the entry point. Quorum AI’s Observer tier is genuinely free (15 discussions / month, BYOK only) with no credit card. Member is $9 / month for 30 discussions and the Commons six-voice pool; Delegate is $19 / month for 100 discussions and all 10 voices including Inner Circle flagships. Suprmind starts at $4 / month (Spark) for the parallel-comparison pattern with managed hosting, $45 / month (Pro) for the full mode set plus the Decision Intelligence Layer (DCI, Adjudicator, DVE) and Master Document Generator. For light deliberation usage on a strict budget, Quorum AI Member or Delegate is the cheaper option. For decision work that produces deliverables, Suprmind Pro is the closer comparison.

Yes. The method patterns map directly: Standard → Super Mind, Oxford → Debate, Advocate → Red Team, Dossiers → Projects, confidence labels → DCI tracking. Suprmind adds Sequential mode (chain-of-models where each reads prior responses), First Principles, Research Symphony (Enterprise), Decision Validation Engine, Adjudicator, and a Master Document Generator with 25+ professional templates exporting to PDF and DOCX. Two methods that don’t have direct named equivalents on Suprmind are Quorum AI’s Delphi (anonymous rounds) and Tradeoff (weighted multi-criteria scoring) — both can be approximated with Super Mind plus prompt structure, but the named methods remain Quorum AI’s.

Sequential mode (each model reads prior responses and adds its own layer), Red Team mode with four explicit attack vectors (Technical Feasibility, Logical Consistency, Practical Implementation, Mitigation Synthesis), First Principles mode (strip assumptions and rebuild), and Research Symphony (Enterprise). Plus a Decision Validation Engine producing GO / NO-GO / GO-WITH-CONDITIONS verdicts with FMEA-style risk register, an Adjudicator writing independent decision briefs, DCI (Disagreement/Correction Index) tracking the full conversation, a Master Document Generator with 25+ professional templates exporting to PDF and DOCX, Smart Visualizations auto-embedded in exports, project workspaces with an auto-extracted Knowledge Graph (Pro+), Master Project for cross-workspace queries (Frontier+), and voice input / output.

Yes — they can fit different jobs. Quorum AI’s Delphi (anonymous estimation) and Tradeoff (weighted multi-criteria scoring) are useful when you want academically named deliberation methods for a specific decision pattern, especially at the $9 / month Member or $19 / month Delegate price point. Suprmind fits when the work product is a deliverable or the decision has consequences: structured deliberation modes (Sequential, Red Team, First Principles), decision validation, and document export in 25+ professional formats. A founder might use Quorum AI’s Delphi for early-stage forecasting questions and Suprmind for the synthesis and deliverable that goes to investors.
