Reading a textbook alone is the slowest way to learn from it. This free, open-source Claude skill, past 1,400 GitHub stars, turns a textbook PDF into narrated web lessons: the formulas and diagrams change step by step as the voice explains them, and every chapter ends with quick checks and practice that grade your math, not just the exact string.
Here's what you get, how to set it up in Claude Code, and the catch.
What it does for you
- Narrated lessons: each chapter is explained out loud while the formulas, diagrams and scenes change on the words.
- Quick checks and chapter practice that grade the math, so 2(x + 1) counts when the answer key says 2x + 2.
- A player with pause, step back and forth, speed, captions and keyboard shortcuts. Your progress is saved per book.
- Every chapter can also export to a 1080p MP4 with subtitles, to watch on your phone.
- See finished examples on the live shelf: Elementary Algebra (68 chapters), Linear Algebra (40), Elementary Physics (9).
