Overview
Papermorph is a skill that has your agent make narrated, animated web books. From a textbook PDF it makes chapter lessons where diagrams and formulas move with the narration, with quick checks and practice; from a story it makes paper-puppet picture books; from a book or idea it makes short documentaries and upright clips for a phone feed. Each book is a folder of static web pages, and chapters can also be exported as MP4 video. It suits teachers, schools, publishers and studios that make learning material.
It makes whole books in one consistent style, with graded quizzes and saved progress, as plain web pages you own rather than one-off videos.

Good to know
You have a textbook chapter and want a narrated lesson students can pause, replay and practise with. Papermorph plans the chapter, voices the script and animates the diagrams to the narration as a static web page.
Limits
- It needs uv, ffmpeg and Playwright's browsers installed first. The maker reports about 10 to 18 US dollars of model usage for one illustrated physics chapter.
- Narration uses Edge TTS online or Kokoro locally for free; painted scenes, ElevenLabs voices and clips made from a still image are paid steps that need an API key.
