What It Does

Submit any question through a web form. Three AI models independently analyze it, then a neutral moderator synthesizes their perspectives into one actionable recommendation. You get the full transcript showing each AI's reasoning plus the final consensus.

Use cases: Business strategy decisions, technical architecture choices, marketing direction, career advice, product pivots — any question where multiple perspectives lead to better answers.

How It Works

A 4-step pipeline from question to consensus recommendation.

Full transcript

Claude (Anthropic)

  • Sonnet 4 model
  • Nuanced reasoning
  • Risk-aware analysis
  • ~$0.015 per query

GPT-4o (OpenAI)

  • Broad knowledge base
  • Structured responses
  • Also serves as moderator
  • ~$0.02 per query

Gemini Flash (Google)

  • Fast inference
  • Multi-modal capable
  • Alternative perspective
  • ~$0.001 per query

Key insight: Each AI responds independently — they don't see each other's answers. The moderator then finds common ground, highlights disagreements, and produces a balanced recommendation.

n8n Workflow Architecture

The complete workflow runs in n8n with parallel API calls and a synthesis step.

Workflow Nodes

Form Trigger

n8n-provided web form collects the user's question. Generates a public URL anyone can access.

Parallel API Calls

Three HTTP request nodes fire simultaneously — Claude API, OpenAI API, and Gemini API — each with the same question.

Response Merge

All three responses are collected and formatted into a structured prompt for the moderator.

Moderator Synthesis

GPT-4o receives all three perspectives and produces a consensus recommendation with areas of agreement and disagreement.

Format Output

A Code node formats the full transcript — each AI's response + the final recommendation — into clean HTML for display.

Credential Setup

  • Anthropic: HTTP Header Auth — header x-api-key with your API key
  • OpenAI: HTTP Header Auth — header Authorization with Bearer YOUR_KEY
  • Gemini: HTTP Query Auth — parameter key with your API key

Setup Guide

Get the AI Board of Directors running in under 10 minutes.

Prerequisites

  • An n8n instance (cloud or self-hosted)
  • Anthropic API key — console.anthropic.com
  • OpenAI API key — platform.openai.com
  • Google AI API key — aistudio.google.com

Step-by-Step

Import Workflow

Upload AI-Board-Simple.json to your n8n instance via Workflows → Add Workflow → Import from File.

Create Credentials

In n8n Settings → Credentials, create 3 new credentials (HTTP Header Auth for Anthropic + OpenAI, HTTP Query Auth for Gemini).

Link to Nodes

Open each API node in the workflow and select the corresponding credential you just created.

Activate

Toggle the workflow Active, copy the Form Trigger URL, and open it in your browser.

Tip: Test with a simple question first — "What's the best programming language for beginners?" — to verify all three APIs respond correctly.

Customization Ideas

Extend the board with additional rounds, models, and capabilities.

Multi-Round Debate

Duplicate Round 1 nodes so AIs can respond to each other's initial takes. Creates richer, more nuanced discussions.

Specialized Boards

Create topic-specific boards with tailored system prompts — Marketing Board, Tech Board, Finance Board — each with domain expertise.

More Models

Add DeepSeek, Llama, Mistral, or any model with an API. More perspectives = richer synthesis.

Other Extensions

  • Memory: Add a database to track previous discussions and reference them
  • Voting: Include a consensus score (0-100%) showing how aligned the AIs were
  • Translation: Add a translation step for multi-language support
  • Persistence: Save discussions to Google Sheets or Postgres for later review
  • Webhook mode: Replace the form with a webhook for programmatic access from your own frontend

Common Issues

  • "Invalid API Key" errors: Verify credentials match the exact format (Header Auth for Anthropic/OpenAI, Query Auth for Gemini)
  • Responses look malformed: Check the "Format Output" Code node — Gemini's response structure may differ from expectations
  • Workflow times out: Increase n8n's execution timeout in Settings, or reduce max_tokens in each API call
  • Form URL not working: Make sure the workflow is toggled Active (top-right toggle in n8n)

Security Notes

  • Never commit API keys to git — use n8n's built-in credential system
  • The form URL is public by default — add authentication if deploying externally
  • Consider rate limiting to prevent abuse if sharing the URL widely
