Frequently asked questions

What is RAG?

Retrieval-augmented generation searches your own documents for the passages relevant to a question, then passes those passages to a model so it answers from your material instead of guessing from training data.

Where does my document index live?

In NodeTool's own vector store (sqlite-vec), on your machine by default. Nothing has to leave your computer — embeddings and retrieval can run entirely on local models.

How do I run RAG in NodeTool?

Open the Chat With Your Documents template below, index a folder of files into a collection, and connect the query and agent nodes — no separate vector database to stand up.
