Questions

What does it need to run?

An n8n account, plus your own Google Cloud Storage and Telegram accounts, and a key for DeepSeek and Gemini. 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 DeepSeek and Gemini. Model calls are billed by the provider, not by n8n.

How long does it take to set up?

Take your time. At 60 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 60 steps before you point it at anything that matters.
