AI-powered calendar & meeting digest with Gmail and GPT-4o/Claude - daily brief

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. 1. Daily Trigger Runs every weekday morning at 7:00 AM using a schedule node. 2. Calendar Parsing Grabs all Google Calendar events for the day and extracts details like: • Event title, time, and duration • Full attendee list • Meeting description 3. 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 4. Brief Assembly Combines: • Event metadata • Attendee research • Recent conversations 5. Email Delivery Renders the Markdown as HTML and sends a polished email to your inbox with: • Meeting timeline & attendees • Key takeaways & extra context • Conflicts & FYIs Setup Steps Prerequisites • n8n instance (self-hosted or cloud) • Google Calendar and Gmail OAuth credentials • OpenRouter key (for GPT-4o or Claude 3.7) Configuration 1.
