NirnAI
What NirnAI is
NirnAI is a web-based assessment and hiring platform for evaluating candidates across roles and domains. It can generate role-specific questions from a job description using Claude, GPT, or Gemini, then combine multiple choice, coding, video, and open-ended questions. Coding challenges provide syntax highlighting, IntelliSense, and automated test validation across nine programming languages. Hiring teams can create workflows with visual stages, pass/fail thresholds, candidate routing, and a Kanban pipeline. Google Calendar and Microsoft Outlook integrations can generate Google Meet and Teams links. Candidates take assessments in a browser without downloads or installations. Proctoring can track browser events, detect faces, send suspicious activity alerts, and optionally record screens; candidates are informed about monitoring, retention periods can be configured, and deletion can be requested. NirnAI describes organization data isolation, SSO, role-based access, and audit trails, and calls itself GDPR and SOC 2 ready. Each plan has a 14-day trial with full features and no credit card required.
