AI-Powered Calendar & Meeting Digest with Gmail and GPT-4o/Claude - Daily Brief

Description

🛠 How It Works

The Daily Calendar Brief is an automated n8n workflow designed to prep you each morning with a rich, executive-style email summary of your day. It pulls data from your calendar, email, and external contact sources to deliver a contextualized, prioritized briefing.

Runs every weekday morning at 7:00 AM using a schedule node.

Calendar Parsing

Grabs all Google Calendar events for the day and extracts details like:
• Event title, time, and duration
• Full attendee list
• Meeting description

Attendee Intelligence

Filters for external attendees and:
• Scrapes recent email threads with them
• Uses Hunter and LinkedIn to enrich attendee info with roles, bios, locations, and recent activity

Brief Assembly

Combines:
• Event metadata
• Attendee research
• Recent conversations
