In short

Bluefish extracts and verifies claims about your brand across ChatGPT, Google AI, Claude, Perplexity and Amazon Rufus, and its Brand Vault publishes your first-party content to model providers as a source of truth. Knowledge Company reconciles that corpus for internal contradictions before anything is declared canonical.

## 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

Bluefish

Ground truth

- **Knowledge Company** - A maintained claim record with substantiation
- **Bluefish** - Ingested first-party content

What fires it

- **Knowledge Company** - A fact changes
- **Bluefish** - Continuous monitoring

What it writes to

- **Knowledge Company** - Every surface the claim appears on
- **Bluefish** - Outbound to model providers

Who buys it

- **Knowledge Company** - Risk, compliance and marketing operations
- **Bluefish** - Brand / CMO

## What they do

Bluefish extracts and verifies every factual claim made about a brand across ChatGPT, Google AI, Claude, Perplexity and Amazon Rufus. Mismatches are traced to the exact response, scored by severity, and filterable by product line and audience.

Brand Vault ingests first-party content as a continuously updated source of truth and shares it with model providers. Bluefish reports 97% cross-engine consistency for brands using it.

## How we differ

Brand Vault takes the corpus you already have and publishes it to model providers as truth. That is a strong distribution mechanism, and it is only as good as the corpus underneath it.

Most corpora contain contradictions — a pricing page and a help centre article that disagree, a datasheet that predates a policy change. Knowledge Company resolves those contradictions first and establishes which version is canonical, so what gets broadcast is a reconciled record rather than an averaged one.

## Which one you want

You want faster distribution of your existing content to model providers, and you are confident that content is already internally consistent.

You want the contradictions inside your own corpus found and resolved before any of it is published as authoritative.
