SourceForge Software Services today launched CognitiveIQ, a three-engine online assessment platform built for students, career counsellors and corporate L&D in India. The platform combines an IQ test, a 150-item Psychometric battery (OCEAN + RIASEC) and a General Knowledge test in a single, editorial-toned candidate experience.
The product is built on Next.js 16, Drizzle on self-hosted PostgreSQL 18 with pgvector, and uses Anthropic Claude Sonnet 4.6 for both question generation and the three-paragraph result narrative every candidate receives. The question bank — approximately 5,000 IQ items and 5,000 GK items — is deduplicated using a pgvector ivfflat similarity index, and every served question is logged to a per-user history table so no candidate ever sees the same question twice across retakes.
Certificates are 16-character IDs in the format CIQ-XXXX-XXXX-XXXXX, drawn from a 29-character no-ambiguity alphabet that excludes 0, O, 1, I, L, U and V. Each certificate is rendered as a PDF using @react-pdf/renderer, stored privately in S3, and carries a QR code that resolves to a public, rate-limited verification page where recruiters can confirm authenticity without a login.
Payment is via Razorpay with UPI as the dominant method; coupons, free-mode windows and bundle pricing for cohort deployments are supported out of the box. Photo identity verification, where enabled, runs every uploaded face image through AWS Rekognition for face-count and content moderation before embedding it into the certificate.
CognitiveIQ is available as a public SaaS at cognitiveiq.in, as a branded deployment with custom certificate templates for institutional customers, and as an on-prem deployment for university IT departments. The AWS deployment runbook in the repository takes a fresh AWS account to a working URL in 90 minutes.
