Turn a book into an interactive course you can run locally in a browser. This Claude skill uses the source material to build beginner-friendly lessons, then adds ways to practise and check what you have learned. It accepts EPUB, PDF, HTML, DOCX, Markdown, and plain text.

• Short lessons with step-by-step explanations, worked examples, diagrams, and animated walkthroughs.
• Interactive quizzes with hints and explanations, chapter tests, and flashcards.
• Programming exercises with starter code, examples, and unit tests. Learners write code in their editor, run the tests from the course page, and see whether their solution passes.
• Progress tracking for lessons, quiz answers, and exercises, saved locally so learners can pick up where they left off.

For coding exercises, the skill checks that the tests fail on the starter code and pass on a reference solution before packaging the course. When a book does not call for code, the course can use other practice activities, such as self-check exercises.

A Go programming course: an animated code walkthrough, a quiz, flashcards, and an exercise whose unit tests run from the page.

A math course: formulas written in LaTeX render in lesson text, tables, quizzes, and flashcards.

This repository is a Claude Code plugin marketplace. In Claude Code, add the marketplace and install the plugin:

/plugin marketplace add sebastianhaba/book-to-course-skill
/plugin install book-to-course@book-to-course

Then attach a book and ask Claude to turn it into a course, for example: "Turn this book into an interactive course."

To update to the latest version later, run /plugin marketplace update book-to-course.

These screenshots show a course generated from a Go programming book:

1. Give the skill a book or document and ask it to create a course. You can specify the course language and scope.
2. The skill extracts the source, plans lessons by chapter, and builds the course as a folder of local web files.
3. Open the generated course with start.sh (macOS/Linux) or start.bat (Windows). The local server saves progress to progress/progress.json and lets the Run tests button execute the exercise's test command on your computer.

Starting the course this way requires Python 3. Programming exercises also require the relevant language and test tools, such as Go for a Go course. You can open index.html directly without the server; quizzes and lessons still work, while progress stays in the browser and code tests must be run in a terminal.

The skill and its supporting scripts, templates, and references are in book-to-course/. Generated courses are self-contained folders that can be packaged and shared.
