Finally figured it out - OpenWeb UI with your own, custom RAG back-end

I posted about this in both the n8n and OpenWebUI forums a day or two ago and I'm posting an update - NOT because I'm selling anything or trying to build subscribers or whatever. So this "repost" is because I genuine think there was enough discussion to indicate an interest.

It's a bit of a read because it's pretty much a diary entry. Read the last section for the answer on how to use OpenWebUI's RAG system - whenever you want - and switch over to full documents - whenever you want - and hand off any uploaded documents to Google for OCR (of PDFs) or to N8N (or any other system) for your own RAG logic - whenever you want:
