Automate Your Lectures: Multilingual Transcriptions & AI Summaries

Transform your educational content delivery with this comprehensive n8n automation that converts lecture recordings into multilingual transcriptions, AI-powered summaries, and personalized WhatsApp delivery – all without manual intervention.

What this workflow does

This end-to-end automation streamlines your entire lecture processing pipeline. Simply upload a recording to Google Drive, and the workflow automatically transcribes content in Arabic, English, or Urdu using AssemblyAI's multilingual capabilities. GPT-4o-mini then generates structured AI summaries, while a human-in-the-loop review system via Google Docs and Gmail ensures quality control before final distribution.

The workflow creates branded PDF summaries and delivers them personally to every registered attendee through WHAPI's WhatsApp integration. Smart conditional branching handles sessions with or without pre-lecture context notes, while configurable approval logic and anti-spam delays protect your delivery reputation. A built-in longitudinal attendance tracker provides valuable funnel analysis data for optimizing your lecture series performance.
