Atlan measures whether the retrieval index is fresh. Knowledge Company measures whether the claim is still true.

Comparison

A data catalog and metadata platform, with a published rubric for scoring knowledge base freshness in AI retrieval systems.

Data catalog / metadata

Last verified Sep 1, 2026

In short

Atlan scopes freshness to the retrieval index — whether documents in the vector store are current. Knowledge Company scopes it to the claim — whether the sentence is still true, wherever it is published.

## The four coordinates

Every company in this landscape can be located by four questions. Applied consistently, the apparent crowding resolves into something much narrower.

Coordinate

Knowledge Company

Atlan

Ground truth

- **Knowledge Company** - A maintained claim record with substantiation
- **Atlan** - Retrieval indexes

What fires it

- **Knowledge Company** - A fact changes
- **Atlan** - Pipeline and index change

What it writes to

- **Knowledge Company** - Every surface the claim appears on
- **Atlan** - Nothing — catalogs only

Who buys it

- **Knowledge Company** - Risk, compliance and marketing operations
- **Atlan** - Data platform lead

## What they do

Atlan is a data catalog and metadata platform. It has published a four-dimension rubric for knowledge base freshness covering content age, embedding lag, stale retrieval rate and coverage drift.

As a framework for evaluating whether an AI retrieval pipeline is current, the rubric is sound and worth reading.

## How we differ

Atlan scopes freshness to the retrieval index: are the documents in the vector store current, and is the pipeline keeping up?

Knowledge Company scopes it to the claim: is the sentence still true, wherever it happens to be published? A rubric that measures whether the pipeline is fresh says nothing about whether the pricing page contradicts the help centre. Both documents can be perfectly indexed and still disagree.

## Which one you want

Your question is whether your AI retrieval pipeline is ingesting current documents.

Your question is whether the statements inside those documents are still correct.
