How to install Book to Course in Claude Code

What it does

Reading a long book and remembering it are two different things. This plugin takes a book or long document and turns it into a small course that runs in your web browser, on your own computer.

A course can have short lessons with examples and diagrams, quizzes with hints, chapter tests and flashcards. Your progress is saved locally, so you can stop and continue later. For programming books it can also add coding exercises with automatic tests.

It accepts EPUB, PDF, HTML, DOCX, Markdown and plain text files. Two extra skills can pack the finished course as an offline Android app or a Linux desktop app, but those need extra developer tools.

Example prompts

"Turn this book into an interactive course"
"Make the course for complete beginners and add flashcards for each chapter"
"Add a short quiz at the end of every chapter"
"Make an APK of this course for my tablet"

How to install

$ /plugin marketplace add sebastianhaba/book-to-course-skill

$ /plugin install book-to-course@book-to-course

How to use it

Attach a book file and ask: Turn this book into an interactive course.

Check it works

Type /plugin in Claude Code and check that book-to-course is installed. To update later, the README gives /plugin marketplace update book-to-course.

Common problems

The plugin commands do not appear — the plugin loads when Claude Code starts — run /plugin to check it is installed and enabled, then restart Claude Code.
The course stops in the middle of a long book — very long files do not fit in one session — give it one part or a few chapters at a time.

What to watch out for

Reads the whole book or document you give it
Writes a course folder with web pages and scripts to your computer
Optional phone and Linux app packaging downloads large extra tools (JDK, Android SDK, Electron)
Only share courses made from material you have the rights to
