Questions
What does it need to run?
An n8n account, plus your own Google Docs, Supabase and WhatsApp accounts, and a key for Gemini. You connect your own accounts after importing it; none are included.
What starts it?
It starts on an incoming WhatsApp message.
Does it use AI?
Yes. It calls Gemini. Model calls are billed by the provider, not by n8n.
How long does it take to set up?
Plan an afternoon. 13 steps is enough that you should read each one before running it.
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.
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 13 steps before you point it at anything that matters.
