# Knowledge Base

> Ground agent answers in your own documents and data

A **knowledge base** stores your documents as embeddings so an agent can
retrieve relevant context and ground its answers in your data
(retrieval-augmented generation).

## Creating a knowledge base

Give it a name and description, and optionally tune how strict the retrieval
matching should be — stricter settings favor precision, looser settings
retrieve more broadly related content.

## Adding sources

A **source** is one unit of content inside a knowledge base — plain text, an
uploaded file, a URL, Google Drive doc, or API-fed content. You can upload
files directly (PDF, DOCX, TXT, MD, CSV, HTML, JSON — up to 50MB) or add a
source by URL.

## Ingestion

Adding a source doesn't make it searchable by itself — it must be **ingested**
(chunked and embedded) first. You can re-ingest a single source or every
active source in the knowledge base at once.

## Attaching to an agent

Link a knowledge base to an agent when creating or updating it to enable
retrieval-augmented responses grounded in that knowledge base.

  Keep each source focused on one topic — a single 200-page manual retrieves
  worse than the same content split into a handful of topic-scoped sources.
