§ The result
Paradox leads XOR by 11 points.
Paradox sits 11 points above XOR under rubric v1.0 — 41 against 30 — with Paradox filed under Scheduling and XOR under Screening. Paradox leads 5 of the 7 criteria, including Bias Audit Transparency, while XOR leads 1, including Customer Documentation, and 1 is level. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Paradox 50, XOR 18 — and at an 18% weight it carries 49% of the weighted advantage Paradox holds across the 5 criteria on that side of the table.
Vendor profile
Paradox
Conversational AI ("Olivia") that screens, schedules, and engages candidates over chat and SMS, often deployed on top of an existing ATS.
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
Paradox is filed under Scheduling AI, XOR 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.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +11.4 — the difference between the two totals before either is rounded. Shares are of 11.9 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +11 beside that +11.4.

§ 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.

Paradox has 10 evidence rows across 7 of 7 criteria — 8 with a source URL, 2 documented absences; XOR has 18 evidence rows across 7 of 7 criteria — 11 with a source URL, 7 documented absences; some documentation or audit rows for Paradox sit on a domain separate from the vendor's own site.
Provenance
The scores above are documented by 28 evidence rows on file for these two vendors: 10 for Paradox, across 2 distinct source domains, and 18 for XOR, across 1 distinct source domain.
