LearnBuilder is AI-powered e-learning authoring software built for instructional designers who care about whether learners actually retain and apply what they learn — not just whether courses get completed. Three AI agents handle production work: the Creator Agent generates course outlines and lesson content from your objectives and uploaded documents; the Tutor Agent provides personalized, on-demand support grounded in your course content (not generic AI); and the Assessment Agent grades open-ended responses and essays with individual feedback — making meaningful assessment scalable. AI Dialogue scenarios are genuinely adaptive: instead of pre-written branching, the AI plays a character and responds to what the learner actually says. The block editor offers full creative flexibility, including interactive slides with a trigger-action system, custom code blocks, hotspot images, and the ability to embed existing SCORM packages directly. LearnBuilder stores courses as open JSON — no proprietary lock-in — and exports to SCORM 1.2, SCORM 2004, and xAPI. Hosting is GDPR-compliant with the option to use European AI providers. Paid plans include unlimited learners, real-time multi-author collaboration, and monthly billing with no annual commitment required.
