Description
Gmail → AI Summary → Notion + Audio Digest
This n8n workflow turns incoming Gmail emails into structured AI summaries and optional audio digests, automatically delivered to Notion and Google Drive.
It is designed to reduce email overload by transforming raw messages into concise, readable, and listenable content.
What this workflow does
On a scheduled basis, the workflow:
Retrieves Gmail messages (all subjects or filtered)
Marks processed emails as read to avoid duplicates
Extracts and normalizes the email body
Uses OpenAI to generate a clean, structured summary
From the summary, the workflow branches into two outputs:
Text summary
The final AI-generated summary is appended as a block in Notion
Ideal for daily logs, knowledge bases, or team dashboards
Audio transcript (optional)
The summary text is converted into speech using a TTS model
The audio file is uploaded to Google Drive
A shareable link is generated
The audio reference is added back into Notion
