AIQuorum

One AI model can be confidently wrong. AIQuorum asks several at once and makes them reconcile. Pose a question and AIQuorum sends it, in parallel, to a panel of leading AI models. A model you pick acts as the leader: it breaks every answer down into individual claims and reconciles them over a few rounds. What comes back is a single answer the panel converged on - plus a convergence score, and the specific points they disagreed on surfaced instead of buried. HOW IT WORKS - Ask in parallel - your prompt goes to several models at once, across OpenAI, Anthropic, Google, and fast open-model hosts. - Reconcile - a leader model decomposes each answer into claims and reconciles them round by round, so agreement is earned, not assumed. - See convergence - read one reconciled answer with a convergence score, and inspect the claims that didn't line up. TWO CONSENSUS MODES - Single judge - a leader model judges and reconciles each round. - Claim-commit voting - claims commit by panel quorum and stay committed (inspired by RAFT). BRING YOUR OWN KEYS Use your own provider API keys. They're stored securely in your device's keychain and used only to call the providers you choose - never sent to us. Mix and match models, run more than one model from the same vendor, and pin whichever one leads. PRIVATE BY DESIGN AIQuorum is a pure client - there's no account and no AIQuorum server. - No analytics, no telemetry, no ad SDKs. - Prompts go straight from your device to the providers you configured. - Chat history is saved locally and stays on your device. Delete any conversation anytime. YOU'RE IN CONTROL Choose which models sit on the panel, which one leads, how many rounds run, and the convergence threshold. Multi-turn chat with local history and Markdown-rendered answers. Supported providers: OpenAI, OpenRouter, Anthropic (Claude), Google (Gemini), and OpenAI-compatible hosts including Groq, Fireworks, and Cerebras - with free open models available. Note: AIQuorum requires your own API keys from the providers you want to use. Provider usage is billed by those providers per their own pricing.
