# Knowledge Base — Private cited retrieval for Fleet agents

> Canonical page: https://knowledgebase.sassmaker.com/

Knowledge Base is the shared retrieval layer behind approved Fleet products and
agents. It searches private, specialized corpora by exact terms or meaning,
ranks the evidence, and returns answers tied to a file, page, and excerpt.

Current consumers include Karte, Research Papers, and Starboard. This is
maintained internal infrastructure, not a public document-chat product or a
self-serve RAG service.

## What it does

- Limits each consumer to its approved project and domain.
- Supports lexical, semantic, and hybrid retrieval over controlled sources.
- Returns ranked citations, provenance, confidence, and trace data.
- Keeps operator workspaces, indexed material, and retrieval access private.

## Operating rule

Knowledge Base already serves real Fleet consumers. Change it for a concrete
consumer need, a retrieval regression, or a new corpus—not to expand the
infrastructure for its own sake.

## Product boundaries

This public landing contains product documentation only. It does not expose
indexed documents, search history, operator settings, private dashboard routes,
or retrieval access. There is no public signup, checkout, or permanent pricing
promise.

The operator workspace is separately protected at https://search.sassmaker.com.

## Website analytics

The public landing uses PostHog for a page-view event and Microsoft Clarity for
session replay and heatmaps. The Access-protected operator workspace also loads
Clarity, but its entire application root is explicitly masked before collection
so private corpus content is not uploaded.
