FairAttest — FACT CertifiedFairAttest
FACT Certified · FACT standard

Independent certification for AI accuracy

FairAttest is a certification authority, not a leaderboard or a consultancy. We test a specific production build of an AI system against controlled synthetic cases where every fact is known in advance, grade each output claim-by-claim, and publish a versioned, procurement-ready attestation.

FairAttest — FACT Certified

What we certify

Controlled ground truth

Synthetic cases with every correct fact and every planted trap known in advance — so fabrication and omission can actually be measured.

Claim-by-claim grading

An AI judge scores every assertion against the source. Consequential findings go to a human reviewer. The human ruling always wins.

A published attestation

A versioned public trust page under FACT (Fabrication, Accuracy & Completeness Testing) — comparable across vendors, tied to a named production build.

How a run works

  1. 1

    Issue cases

    We serve controlled synthetic cases one at a time, with clocks that make special handling impractical.

  2. 2

    Collect outputs

    Your production AI processes each case. We never invoke a tuned benchmark build — we grade what customers get.

  3. 3

    Grade & review

    Every claim is grounded against the source. Low-confidence and high-severity findings go to a reviewer.

  4. 4

    Publish

    A FACT tier is awarded against public thresholds and signed onto a public trust page.
