End-to-end AI blog research and writer with Gemini

Started by a clock, and works across Supabase. It hands the judgement calls to Gemini and Groq. 42 steps, 2 branches, 4 loops or waits: large, and worth reading before you trust it with anything live.

Questions

What does it need to run?

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

What starts it?

It starts on a clock.

Does it use AI?

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

How long does it take to set up?

Take your time. At 42 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 42 steps before you point it at anything that matters.
