Built at Built with Opus 4.6: a Claude Code hackathon · Feb 10, 2026

ClassBuild turns a topic description into a complete, multimedia course in minutes — structured syllabus, research with validated citations, interactive readings, practice quizzes, in-class assessments, discussion prompts, activities, narrated audio, slide decks, and AI infographics. Every output is shaped by five evidence-based learning principles: retrieval practice, interleaving, dual coding, concrete examples, and spacing. Opus 4.6 powers a five-stage pipeline — curriculum design, learning principle mapping, research synthesis, content generation, and assessment — where each stage feeds into the next. The science isn't applied as a finishing pass; it shapes the course from the first step. Runs entirely in the browser, no backend. Any subject-matter expert can produce pedagogically sound materials for any topic, any audience.
