Stage 0: Ready

Why Synod?

Single-model agents hallucinate. Synod debates until the wrong idea dies.

🎯

Single AI hallucinates

Multiple models catch each other's mistakes

🧠

Context resets every session

Memory that learns your codebase and preferences over time

♾️

Token limits run out

Intelligent retrieval injects only what's relevant

Can't trust AI suggestions

Every answer survives adversarial peer review

Pay for intelligence, not repetition.

Smart retrieval injects only relevant memories. Consensus detection skips unnecessary debates. You save tokens while getting better answers.

How It Works

Four stages of orchestrated intelligence that produce battle-tested code

01

Classification

Free pre-debate analysis determines complexity, domains, and optimal debate strategy.

02

Proposals

Multiple SOTA models (Claude, GPT, Gemini, Grok, DeepSeek, GLM) independently propose solutions in parallel.

03

Adversarial Critique

Smart dynamic rounds - models attack each other's code until consensus or critical issues are resolved. Exits early when safe.

04

Synthesis

The "Pope" verifies consensus isn't collective blindness, then combines the best ideas into a hybrid solution.

Why pick a model when you can orchestrate all of them?

Not consensus — synthesis.

Frequently Asked Questions

Everything you need to know about Synod

Synod is an AI coding agent that uses multiple AI models (Claude, GPT, Gemini, Grok, DeepSeek, GLM) in a debate format. Models propose solutions independently, then critique each other's work to catch bugs and hallucinations. A "Pope" model synthesizes the best ideas into a final, battle-tested answer.
Single AI tools give you one model's best guess. Synod orchestrates multiple models that challenge each other, so errors get caught before they reach you. It also has infinite semantic memory that persists across sessions, learning your codebase and preferences over time.
BYOK means you use your own API keys from providers like OpenAI, Anthropic, Google, etc. Your keys are encrypted and used directly. We never see your queries or code. This gives you full control over costs and ensures your data flows directly to the AI providers.
Your code and queries are never stored - period. They pass through to AI providers and are immediately discarded. We only save synthesized insights (like "prefers TypeScript" or "uses React hooks") to power your memory. Your original code and conversations never touch our database. All data is encrypted at rest.
Synod supports 6 AI providers with direct API access: Anthropic (Claude), OpenAI (GPT), Google (Gemini), xAI (Grok), DeepSeek, and Zhipu (GLM). For enterprise deployments, you can also connect through Azure or AWS Bedrock.
Unlike tools that reset every session, Synod maintains persistent memory that learns and adapts. After each debate, we extract synthesized insights - never your actual code or queries. For example, "uses functional components" or "prefers async/await over promises". These insights are stored securely with semantic embeddings for retrieval. When you ask a question, only relevant memories are injected, saving tokens while preserving context.
Yes! The Synod CLI is fully open source under the MIT license. You can inspect the code, contribute, or self-host. The cloud service adds convenience features like key management, memory persistence, and usage analytics.
Synod has a generous free tier with 10 debates/day using your own API keys (BYOK). Pro ($19/mo) includes unlimited debates, up to 6 models, infinite memory, skill learning, memory visualization, and enhanced debate depth. Team ($49/mo for 5 seats) adds shared team memory where your team learns from each other, cross-project insights, admin dashboard, and SSO.
