This n8n workflow automates the entire audio-to-report pipeline. It monitors a Google Drive folder for new audio recordings, transcribes them using OpenAI’s Whisper model, summarizes the content into structured reports, and saves both JSON and Markdown versions back to Google Drive. It can optionally notify users via Gmail and Telegram with links to the generated reports, making it a perfect “human-in-the-loop” transcription and reporting solution.
