The steps in the order they run, from what starts it.

- 1 **Start Manual Ingestion** Manual trigger *Starts it*
- 2 **Generate Embeddings Ollama** Embeddings Ollama *Model*
- 3 **Split Text for Processing** Text Splitter Recursive Character Text Splitter *Model*

## How it's built

- **Starts on:** An event in a connected app
- **Steps:** 6
- **Size:** Small: readable in one sitting
- **Connects to:** Supabase vectors
- **Model:** None. This is plumbing, not judgement
- **Retrieval:** Answers are drawn from documents you supply, not from the model alone

## Questions

What does it need to run?

An n8n account, plus your own Supabase vectors account. 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?

No. Every step is fixed logic or a call to a service, so it does the same thing every time.

How long does it take to set up?

Not long. At 6 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 6 steps before you point it at anything that matters.

## Run it in n8n

- **Create your n8n account** Free to start. n8n is where the workflow runs. [Create an n8n account ↗](https://millionrounds.com/n8n)
