Description
AI Meeting Intelligence System
> Zoom + n8n + GPT-4o + Supabase RAG
This n8n workflow automates Zoom meeting intelligence by capturing recordings via webhook, transcribing audio using OpenAI Whisper, analyzing it with GPT-4o and storing structured insights in Supabase vector database. It detects summaries, decisions, action items and contradictions, then sends an email report to stakeholders.
Quick Implementation Steps
- Import workflow json in your n8n account
- Connect Zoom webhook for recording events
- Configure OpenAI API (Whisper + GPT-4o)
- Set up Supabase
meeting_memoriestable with vector support - Add embeddings credentials in n8n
- Activate workflow and test with a Zoom recording
What It Does
This workflow automatically processes Zoom meeting recordings and converts them into structured intelligence. It extracts transcript text, analyzes it using GPT-4o and generates structured insights like decisions, summaries and action items.
It also compares new meetings with historical data using Supabase vector search to detect contradictions or repeated decisions.
Finally, it stores everything in a semantic memory database and sends a clean email report to stakeholders.
Who Itβs For
- Product Managers
- Engineering Teams
- Startup Founders
- Project Managers
- AI Automation Engineers
- Remote teams using Zoom
Requirements to Use This Workflow
- n8n account (cloud or self-hosted)
- Zoom account with webhook access
- OpenAI API key (Whisper + GPT-4o)
- Supabase project with vector enabled
- Gmail OAuth credentials
- Public webhook URL
How It Works & Setup Guide
1. Zoom Ingestion Layer
Zoom webhook captures meeting recording events and sends metadata like recording URL and meeting title to n8n.
2. Data Extraction Layer
The workflow extracts recording URL and metadata using a set node.
3. Audio Processing Layer
Audio is downloaded from Zoom cloud and sent to OpenAI Whisper for transcription into text.
4. Transcript Normalization Layer
The raw transcript is cleaned and formatted into a structured format for AI processing.
5. AI Intelligence Layer (GPT-4o)
GPT-4o analyzes the transcript and extracts:
- Summary
- Decision
- Action items
- Contradiction report
Structured output parser ensures valid JSON format.
6. Deduplication Layer
A hash is generated from the transcript and checked in Supabase:
- If duplicate exists β stop workflow
- If not β continue processing
7. RAG Memory Layer
Embeddings are created and stored in Supabase vector DB. Past meetings are retrieved to compare decisions and detect contradictions.
8. Notification Layer
Final structured output is stored and emailed to stakeholders with insights.
How To Customize Nodes
- Modify GPT prompt for domain-specific intelligence
- Extend metadata with project/client IDs
- Replace Gmail with Slack or Teams integration
- Add Jira task creation for action items
- Customize Supabase schema for multi-team support
Add-ons
- Slack real-time meeting alerts
- Jira auto task creation
- Dashboard using Supabase + Next.js
- Multi-language transcription support
- Speaker identification using Whisper timestamps
Use Case Examples
- Automated meeting minutes generation
- Engineering decision tracking system
- Product requirement documentation automation
- Client meeting summaries
- Compliance audit trail generation
More use cases can be built depending on customization.
Troubleshooting Guide
| Issue | Possible Cause | Solution |
|---|---|---|
| No transcript generated | Invalid Zoom recording URL | Check webhook payload |
| Duplicate not detected | Incorrect Supabase query path | Fix metadata filter |
| Empty AI response | Weak prompt structure | Improve prompt clarity |
| Email not sent | Gmail auth expired | Reconnect Gmail OAuth |
| Supabase returns empty | Wrong filter syntax | Validate JSON column query |
