Learnosity is an assessment infrastructure platform exposing a full suite of APIs that cover every stage of the assessment lifecycle — authoring, delivery, scoring, and reporting. It offers 50+ question types out of the box, AI-powered essay scoring and written feedback via Feedback Aide, and is built to scale to 4M+ concurrent users per day with 24B+ questions delivered annually. Security and compliance are production-ready: ISO 27001 certified, and compliant with GDPR, FERPA, and COPPA. Accessibility meets WCAG 2.2 AA. Integration is designed for speed — teams typically move from proof of concept to production in weeks. Pricing is custom, based on usage and monthly active users.
