Mentingo is an open-source learning management system where employees practice real workplace conversations with an AI mentor instead of only clicking through slides. The voice and chat mentor plays a customer, candidate, or colleague in role-play scenarios, asks follow-up questions, and returns scored feedback on how the conversation actually went. You can generate a course draft from your own documents, presentations, and procedures, then edit the structure and lessons instead of starting from a blank page. Learners work through a course catalog and distraction-free lessons, while quizzes, scenario questions, and long-form answers check understanding beyond simple recall. Compliance and safety courses can expire on a schedule, with automatic re-enrolment, reminders, and certificate validity tracking keeping renewals from slipping. Administrators organize people by departments, branches, and teams, inherit course access from group membership, and follow engagement and completion analytics per learner, group, and course. A knowledge base, company blog, announcements, and FAQ keep supporting material beside the training itself. Multiple organizations can share one deployment with separate domains and branding, and courses can be exported as SCORM packages for other tools. Integrations include Microsoft 365, Google Workspace, and Slack sign-in, plus an MCP endpoint for AI assistants.
