Automated FAQ generator from WhatsApp groups using GPT-4 and Google Docs

What’s up guys, I’m Luís 🙋🏻‍♂️

If you manage learning programs, communities, or customer groups on WhatsApp, this workflow will save your life. It’s your AI-powered FAQ engine.

This workflow captures group conversations (via Google Sheets), identifies the most common doubts and recurring questions, and automatically builds a structured FAQ document with suggested answers.

⚠️ Important note To use this workflow, you must already have all WhatsApp conversations saved into a Google Sheet. If you don’t have this yet, check out my other workflow that does exactly that: [Workflow to Summary Group WhatsApp](https://n8n.io/workflows/7141-workflow-to-summary-group-whatsapp/).

✅ What this workflow does
