Request an FVR Score for a competitor tool
FVR (False-Verify Rate) is the rate at which a citation-checking tool wrongly marks a bad citation as “verified.” We publish our own FVR against a held-out eval set every week. Ask us to run the same eval against another vendor’s product and we’ll review the request and publish a score if we can get access to test it.
We only publish an FVR score once we’ve actually run the vendor’s product against our held-out citation eval set. Requests are reviewed manually, not auto-published — this keeps the database honest rather than a flood of unverified claims.
