Constructor Learn is built for organizations that teach, grade, and examine in one platform. Instructors grade with rubrics and a gradebook with grade weights, run graded text, audio, and video discussions, and hold video classes inside Learn. Exams come from Constructor Assess and are proctored through Constructor Proctor, an AI tutor guides each learner step by step with questions, and content comes in through LTI 1.3, SCORM, and H5P.
Kallidus does several things better for employers that run mandatory training. Learn is built around compliance: group rules add people to groups and assign courses automatically, accreditations expire and renew with reminders to learners and managers, and Power BI reports show completions and gaps, with scheduled data exports to SFTP. It adds an off-the-shelf library of more than 250 scenario-based courses, Pathways, an AI skills suite, connectors for HR systems such as Workday and ADP, and Perform for performance management from the same vendor. Learn is hosted on Microsoft Azure in the UK, and its privacy policy cites ISO 27001.
Both offer AI course recommendations, learning paths, recertification, skills tracking, reports, an API, single sign-on, and offline mobile access. Choose Kallidus for compliance-led employee training with a ready-made course library, and Constructor Learn if you want rubrics, a gradebook, built-in video classes, and proctored exams in the same platform.
