Self-Hosted AI Knowledge Bot in n8n — Index new documents
Every time a question arrives via webhook from your site chat, this workflow hands it to Claude, which chunks and embeds the document into your vector store. You get your knowledge base kept up to date automatically without lifting a finger.

Frequently asked questions
Does this need n8n Cloud or can I self-host?
Either works. The workflow is a standard n8n export, so you can run it on n8n Cloud or on your own self-hosted instance — you only connect your own app credentials.
How do I import the workflow into n8n?
Download the JSON, then in n8n open a new workflow, choose ⋯ → Import from file, and select it. Every trigger, node and connection appears on the canvas; you just add your credentials and activate it.
How much does the AI part cost to run?
Pennies. Each run sends a small amount of text to the model, so most teams spend a few dollars a month even at hundreds of runs. You set the model and can cap volume in n8n, so costs never surprise you.
