4. Service Description and Nature of the AI System

What Smart Sifty Does: Smart Sifty is an AI-assisted scoring system that processes Job Descriptions and candidate CVs and produces structured analytical output (category-level scores, an overall match score, and written observations) to support recruiter judgment.
What Smart Sifty Does Not Do: Smart Sifty does not make hiring decisions. It does not contact candidates, does not reject candidates, does not progress candidates, and does not take any action on candidates without explicit human initiation by the Client.
Decision-Support Nature: Scoring Output is informational and intended to support human decision-making. It is not a binding recommendation, not a hiring decision, and not a substitute for the recruiter's professional judgment.
Underlying Models: Smart Sifty operates Aurora and Meridian as product profiles configured on top of third-party foundation models (currently provided by xAI Corp. and Anthropic via AWS Bedrock respectively). Neither model is trained, fine-tuned, customised or modified by CORTX AI LIMITED in respect of its weights.
Inference Region: All foundation model inference is performed in EU regions, supporting EU/UK data residency requirements for personal data processing.

6.2 Meaningful Human Review

Before any hiring, screening, rejection, progression or candidate-contact decision is taken in relation to a Candidate, a qualified human decision-maker on your side must perform meaningful review of the Candidate's record, including the original CV and the Scoring Output. This obligation applies whether you access the Service through the web application or via the API.

6.3 No Automated Decision-Making

You agree not to deploy the Service in any workflow that automates rejection, progression, contacting, interviewing or hiring of Candidates without meaningful human review. The Service is not designed to and must not be used to make solely-automated decisions within the meaning of GDPR Article 22.
