Active quizzing
Claude quizzes you interactively, not just summarises. You actually retain what you study.
Structured notes
Concepts, commands, and quiz questions saved automatically — with Mermaid diagrams where helpful.
NotebookLM helps you look things up. TextbookRobin helps you actually learn — it quizzes you, tracks your progress chapter by chapter, and saves structured notes automatically.
