## Questions

What does it need to run?

An n8n account, and a key for a language model. You connect your own accounts after importing it; none are included.

What starts it?

It starts on an event in a connected app.

Does it use AI?

Yes. It calls a language model. 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.
