Get Daily Calendar Summaries via SMS with Google Calendar, Twilio and Claude AI

Description

This free n8n automation helps anyone—from busy parents to entrepreneurs—get a daily SMS summary of their calendar events. It’s a personal assistant that gives you a heads up of what your day will look like.

Great for: starting your day cognizant of the day's events, or for the neurodivergent.

Example use case:
Parent receives a text summarizing the Family Calendar events at 5AM. Its a reminder of a child's doctor appointment at 1PM and soccer practice at 430PM. The AI then ends the message on an uplifting note.

Good to Know
Requires user to buy a Twilio phone number to send SMS from. Each message, at the time of writing, is $0.083 CAD.
Requires basic knowledge of Google Cloud Console for the activation of Google Calendar API

How it Works
Every morning at 7AM, your workflow checks Google Calendar for the day’s events.
It formats your schedule into a friendly, easy-to-read summary using your favorite AI model (any LLM works—Anthropic, OpenAI, Gemini, etc).
That summary is texted directly to your phone via Twilio as a personal daily reminder.

How to Use
Copy this n8n workflow into your own instance.
Hook up your Google Calendar and Twilio accounts. You can choose the specific calendar in the Calendar node.
Choose or swap in any AI model you prefer to personalize your summaries. I find Claude sounds the most natural.

Enjoy your daily, cheerful calendar digest by SMS at 7AM!

Requirements
A Google Cloud account (to activate the Calendar API and get credentials—see Google documentation).

Any LLM API account (optional, but recommended for polite/friendly summaries).
