What is an AI knowledge base (RAG)?

A knowledge base, in the context of an AI chatbot, is the collection of business content the bot is allowed to answer from: crawled web pages, pasted articles and FAQ pairs, split into chunks and indexed as embeddings. At reply time the most relevant chunks are retrieved and given to the model as context, a pattern called retrieval-augmented generation (RAG).

Knowledge base (RAG)

A knowledge base, in the context of an AI chatbot, is the collection of business content the bot is allowed to answer from: crawled web pages, pasted articles and FAQ pairs, split into chunks and indexed as embeddings.

Why it matters

Without a knowledge base a language model answers from general training and invents specifics; with one, answers cite your prices, hours and policies. The quality of the base decides the quality of the bot: stale pages give stale answers, and a thin base makes the model guess. Scoping bases per widget or channel keeps a support bot from quoting the sales page.

In VGraple CRM

Sources are added under the chat widget or channel settings as URLs to crawl, pasted text or FAQ pairs; content is chunked at about 512 tokens with overlap, embedded, and re-indexed when a source changes. The five most relevant chunks are passed to the model. The knowledge base guide covers what to include and how to test.

Frequently asked questions

Can I upload PDFs?
Not directly today. Paste the document's text as an article; URL crawling and FAQ pairs are the other source types.
How often is a crawled URL refreshed?
On demand from the source's re-crawl action; set a reminder when pages change.
Is my knowledge base shared with other customers?
No. Each workspace's base is isolated and used only for its own bots.
