What This Workflow Does

This automation solves the problem of calendar overload by delivering concise, AI-powered summaries of your daily schedule directly to your phone via SMS. Instead of constantly checking multiple calendar apps or missing important events buried in notifications, you get one clear message each morning (or at your preferred time) with all key events formatted for easy reading.

The workflow connects Google Calendar with Twilio SMS and Claude AI to transform raw calendar data into human-friendly summaries. It identifies key details like meeting locations, participants, and video call links, then presents them in a natural language format that's optimized for quick mobile reading.

How It Works

1. Scheduled Trigger

The workflow activates daily at your specified time (default is 7 AM) through n8n's scheduler. This ensures you receive your summary at the optimal moment for planning your day.

2. Calendar Data Retrieval

The system connects to your Google Calendar via OAuth and retrieves all events scheduled for the current day. It filters out declined events and optional appointments based on your preferences.

3. AI Processing

Claude AI analyzes the calendar data, identifying patterns and priorities. It transforms the raw event list into a conversational summary that highlights:

  • Time blocks with back-to-back meetings
  • Important vs. optional events
  • Travel time between locations
  • Video call access details

4. SMS Delivery

Twilio sends the polished summary to your designated phone number. The message is optimized for SMS length constraints while maintaining all critical information.

Who This Is For

This workflow benefits anyone with a busy schedule who wants to stay organized without app overload:

  • Executives and entrepreneurs managing packed meeting calendars

  • Anyone who prefers SMS over app notifications for critical reminders

Frequently Asked Questions

Common questions about calendar automation and SMS notifications

SMS calendar summaries provide instant visibility of your schedule without needing to open apps. They help busy professionals stay organized by delivering key event details directly to their phones. This reduces context switching and ensures you never miss important meetings or deadlines.

For example, a sales director might receive a morning SMS showing all client calls, internal standups, and deadline reminders formatted clearly. The AI prioritizes urgent meetings and even suggests optimal travel routes between locations when physical meetings are scheduled.

  • Eliminates app-switching to check schedules
  • Provides at-a-glance visibility of time commitments
  • Reduces cognitive load of managing multiple calendars

AI like Claude transforms raw calendar data into natural language summaries that are easier to digest. Instead of just listing events, it can highlight priorities, estimate travel times between locations, and even suggest preparation tasks based on meeting topics.

  • Converts data into actionable insights
  • Adapts phrasing based on event importance

  • Business systems for data enrichment

Unlike generic apps, this solution offers complete customization of content, timing, and delivery. You control exactly what information appears and how it's phrased. It also works across all your calendars without requiring new app installations.
