## Questions

What does it need to run?

An n8n account, plus your own Google Calendar, Google Sheets and Twilio accounts, and a key for OpenAI. You connect your own accounts after importing it; none are included.

What starts it?

Nothing starts it automatically. You run it by hand.

Does it use AI?

Yes. It calls OpenAI. Model calls are billed by the provider, not by n8n.

How long does it take to set up?

Not long. At 4 steps it can be read in one sitting and changed without fear.

How do I import it?

Copy the workflow, open a new workflow in n8n and paste. The steps appear on the canvas, ready for your own accounts.

**Before you run it**

Nothing here has been tested by us. It is somebody's working automation, read and described from its own steps. Treat the connections it wants as a list of accounts it will touch, and read the 4 steps before you point it at anything that matters.
