§ The result
XOR leads Mercor by 7 points.
XOR scores 30 and Mercor 23 under rubric v1.0 — a 7-point gap inside the Screening cohort. XOR leads 5 of the 7 criteria, including Data Governance Disclosure, while Mercor leads 2, including Article 11 Technical Documentation. Data Governance Disclosure is both the widest raw gap and the heaviest weighted swing — Mercor 22, XOR 42 — and at a 15% weight it carries 41% of the weighted advantage XOR holds across the 5 criteria on that side of the table.
Vendor profile
Mercor
Mercor is an AI talent platform that runs automated 20-minute AI video interviews and semantic resume/profile matching to vet, score, and place candidates and expert contractors, and offers an enterprise applicant-screening product that scores employers' applicant pools against role rubrics with pass/fail recommendations.
Vendor profile
XOR
XOR is a text-first conversational-AI recruiting platform that pre-screens and scores high-volume and hourly candidates with recruiter-defined knockout/scoring questions over SMS, WhatsApp, and Messenger, then auto-schedules interviews on the recruiter's calendar.
§ The record
Mercor and XOR are both filed under Screening AI. They record no secondary category in common.
Both are in scope of EU AI Act, NYC LL 144, Colorado AI Act and Illinois HB 3773. Only Mercor is in scope of Mobley v. Workday.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -6.7 — the difference between the two totals before either is rounded. Shares are of 8.0 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -7 beside that -6.7.

§ Evidence
Cited sources and documented absences, criterion by criterion.
An absence is a finding, not a blank: the reviewer looked for a named artefact and recorded that it is not located. Where a source sits is a fact about hosting only.
