Index and update web knowledge base with Jina and Gemini

Started by someone submitting a form, and works across Supabase vectors and n8n data table. It puts Gemini behind a retrieval step, so answers are drawn from documents you supply rather than from the model alone. 20 steps, 3 branches, 2 loops or waits: a working afternoon to understand properly.

Questions

What does it need to run?

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

What starts it?

It starts on someone submitting a form.

Does it use AI?

Yes. It calls Gemini. Its answers draw on documents you give it, not on the model alone. Model calls are billed by the provider, not by n8n.

How long does it take to set up?

Plan an afternoon. 20 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.

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 20 steps before you point it at anything that matters.
