DozenTwelve / Papermorph

A Skill that turns PDFs into animated interactive web books. 
You've seen Opus 5.5 one-shot videos.
This Skill takes it further: books you can explore, listen to, and interact with.

 Use the Skill 
 Watch the full 75-second demo with narration 
 [code] 
The Skill starts by asking: it finds your PDF, says what the book is, suggests a chapter to try and an animation tier, and offers options at every step, so you can just pick the recommended one. Your choices are saved in `style.json`, the style every later chapter is made against.
**Today:** Built with Opus 5.5, and tested with other models (see Models). No image models, multilingual support, or BGM yet.
## Roadmap
- [x] **Math books:** formulas and diagrams that change step by step, with quizzes. Two books on the shelf.
- [ ] **Physics books:** illustrated scenes, acting characters and camera work. Chapters 9–12 are on the shelf; chapter 12 was made by the new Skill.
- [x] **Picture books:** short films of paper puppets from a story, a joke or a fairy tale; sets drawn in code or painted by an image model. *Little Red Riding Hood* and *Joke Collection* are on the shelf.
- [ ] **Humanities documentaries:** history and social science titles.
Along the way, the bookshelf grows and new Skills are released.
## Get started
Install in your project directory:
 [code] 
In Claude Code with Opus 5.5, run:
 [code] 
It looks for the PDF in your project, then asks the rest. Diagrams that change (tier 1) suit maths and other abstract topics; illustrated scenes (tier 2) suit physics and stories. For a picture book, bring a story instead of a PDF. Documentaries are coming.
Before you review a chapter, `scripts/lint.py` catches broken names, missing audio and stale narration in under a second.
## Player and engine
Every book plays in the same player: speed control (` `), click anywhere on a step to jump there, captions, keyboard shortcuts, and progress saved per book.
The player engine lives in `engine/`, apart from the Skill, so a fix reaches every book without touching the Skill. Fork it if you like, and point the Skill at your fork:
 [code] 
## Export to video
Any chapter can be rendered to MP4 (1080p) with an `.srt` for YouTube or Bilibili:
 [code] 
Frames come straight from the lesson clock, so the video matches the page. Quizzes stay in the interactive version; the video ends by pointing there.
## Models
The Skill is not tied to one model. Books on the shelf show the results:
- **Opus 5.5:** most of the books, including the physics chapters.
- **GPT-6.1-Sol:** runs the Skill well. See *Elementary Mathematics*, chapters 4–20.
- **Sonnet 5.5:** works, with some rough edges. See *Elementary Mathematics*, chapters 21–22.
## Official alternative
Claude now offers official animated explainers (Claude Motion, in beta), which overlap with much of what this Skill does. For token efficiency, the official tool may be the better choice.
I will still finish Papermorph along its roadmap. B
