## Questions

What does it need to run?

An n8n account, plus your own Airtable account, and a key for Gemini and OpenAI. You connect your own accounts after importing it; none are included.

What starts it?

It starts on another system calling it.

Does it use AI?

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

How long does it take to set up?

Take your time. At 51 steps it is large: read it before trusting it with anything live.

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 51 steps before you point it at anything that matters.
